1. SCIENCE 5 QUARTER 4 WEEK 3 DAY 1 Factors Affecting Weather

2. Review: Enumerate the different agent of soil erosion. 1. 2. 3. 4. 5

3. Observe the short clip video below:

4. What can you say about the picture? Have you experienced that kind of scenario? Which agency is responsible in studying the weather in the Philippines?

5. The Philippine Atmospheric Geophysical and Astronomical Services and Administration (PAGASA) is the agency that is responsible for studying the weather of the country. With technology like satellites and radar PAGASA can accurately predict the weather system. PAGASA forecast weather system daily weather bulletins and rainfall forecast

6. Weather is the condition of the atmosphere for a short period. It has different factors; when these factors change and affect the condition of the atmosphere, weather disturbances may occur.

7. Directions: Arrange the following jumbled words to identify the factors that affect the weather. Write your answers in your science notebook. 1. PAMRTEUETER 2. DHIYUITM 3. DNWI 4. CNPTOIRIEPAIT 5. CLSUNDOIES 6. CPMSHAEORIT ESREPRUS

8. Answer: 1. TEMPERATURE 2. HUMIDITY 3. WIND 4. PRECIPITATION 5. CLOUDINESS 6. ATMOSPHERIC PRESSURE

9. Factors affecting the weather. 1. Temperature : Temperature is a measure of the average kinetic energy of molecules in the air. It affects weather by influencing air density, which in turn affects air pressure and wind patterns. Higher temperatures generally lead to warmer weather, while lower temperatures result in colder weather.

10. 2. Humidity: Humidity is the amount of water vapor present in the air. High humidity levels can make the air feel hotter than it actually is because it reduces the body's ability to cool itself through sweating. Humidity also plays a role in the formation of clouds and precipitation.

11. 3. Wind : Wind is the movement of air across the Earth's surface. It plays a crucial role in weather patterns by transporting heat and moisture around the globe. Wind direction and speed can influence temperature, precipitation, and cloud formation.

12. 4. Precipitation : Precipitation refers to any form of water, liquid or solid, that falls from the atmosphere to the Earth's surface. It includes rain, snow, sleet, and hail. Precipitation is a key component of the water cycle and is closely linked to temperature and humidity.

13. 5. Cloudiness : Cloudiness refers to the amount and type of clouds present in the sky. Clouds can affect weather by reflecting sunlight, which can cool the Earth's surface, or by trapping heat, which can warm the atmosphere. Clouds also play a role in the formation of precipitation.

14. 6. Atmospheric Pressure : Atmospheric pressure is the force exerted by the weight of the air above a given point on the Earth's surface. It affects weather by influencing the movement of air masses. High-pressure systems are associated with fair weather, while low-pressure systems are associated with unsettled weather and precipitation.

15. True or False. Write True if the statements is correct and False if not. 1. Warmer air holds more moisture than colder air, which is why humidity levels tend to be higher in warmer weather. 2. Humidity is the main factor that determines how hot or cold we feel, rather than the actual air temperature.

16. 3. Wind is caused by the uneven heating of the Earth's surface by the sun, and it can transport heat and moisture. 4. Precipitation occurs when clouds become too heavy with moisture and the water droplets or ice crystals fall to the ground. 5. Clouds always indicate that precipitation is imminent.

17. Answer Key: 1. True 2. False 3. True 4. True 5. False

26. SCIENCE 5 QUARTER 4 WEEK 3 DAY 2 Different Weather System in the Philippines

27. Review: What are the different factors affecting Weather?

28. Look at the picture: What can you say about it?

29. The Philippines experience different weather conditions. Let’s find out!

30. Different Weather System in the Philippines Cyclones

31. Cyclone a system of winds rotating inward to an area of low atmospheric pressure, with a counterclockwise (northern hemisphere) or clockwise (southern hemisphere) circulation Cyclones are born over bodies of water and die over landmasses.

32. Cyclones are categorized based on wind speed;  Tropical Depression: 61 kph  Tropical storm: 62 – 82 kph  Severe tropical storm: 89 – 117 kph  Typhoon: 118 kph  Super typhoon: 200 kph

33. Breezes are the winds which blow onto the shore from the sea during daytime and away from the shore during nighttime.

34. Two Types of Breezes Sea Breezes are winds that blow inward toward land from the ocean. It occurs during the day when the air over the land is warm and has a lower pressure and the air over the water is cool and has a higher pressure

35. Land Breezes At night, the air over the water is warmer than the air over the land, since land loses heat quickly while water takes much longer to cool down. As a result, the pressures over the land and water are the reverse of what they are during the day; the pressure over the land is high, while the pressure over the water is low.

36. Monsoon is a seasonal change in the direction of the prevailing, or strongest, winds of a region. Monsoons cause wet and dry seasons throughout much of the tropics.

37. Two types of Monsoons; Northeast Monsoon - In the Philippines, we called Hanging Amihan . - It brings cooler air from October to February Southwest Monsoon - In the Philippines, we called as Hanging Habagat - It causes rain and storm from May to September

38. Intertropical Convergence Zone (ITCZ) - is the group of clouds that bring weak to moderate rains and few thunderstorms - it forms due to the clashing winds from the Northern and Southern Hemisphere - moves north in the Northern Hemisphere during summer and south during the cold season - is responsible for the wet and dry season in the countries near the equator like the Philippines

39. Effects of the Weather System in the Philippines  Flooding  Landslide  The distraction of humans living  Affects human’s health

46. Review! DIRECTIONS: Read the questions carefully. Choose your answer in the box and write it in the space provided.

47. ________1. It is a tropical cyclone that has a wind speed of 62 – 82 kph ________ 2. It is the group of clouds that bring weak to moderate rains and few thunderstorms. ________ 3.It is a wind that blows inward toward land from the ocean. ________ 4. It is causes rain and storm in May to September ________ 5. It is a seasonal change in the direction of the prevailing, or strongest, winds of a region.

48. Look at the logo below; What is the meaning of PAGASA? What are their responsibilities?

49. The Philippines is located in a region prone to various weather disturbances due to its geographical location.

50. A weather disturbance is a term used to describe a change in atmospheric conditions or weather patterns. Weather Disturbances are also referred to as natural disasters , as they are capable of wreaking havoc on roads, power lines, and buildings.

51. Different Weather Disturbances Depression The first stage of a tropical weather event is called a tropical depression. Meteorologists sometimes refer to these formations as a tropical wave, disturbance, feature, system, or disturbance.

52. Tropical depressions are cyclones with winds that gust at 38 miles per hour (33 knots) or less. While cyclones aren't as strong as tropical storms or hurricanes, they can bring significant amounts of rain, thunderstorms, and devastating floods.

53. A depression exists when there is a low- pressure area over a large enough area to be plotted on the weather map. The low pressure near the ocean surface draws in warm, moist air which feeds more thunderstorms.

54. The wind swirls slowly around the low -pressure area at first. As the pressure becomes even lower, warmer moist air is drawn in, and winds blow faster.

55. Storm Meteorologists upgrade a tropical depression to a tropical storm when the cyclone's circulation ismore organized and has sustained wind speeds of 39 to 73 miles per hour (34 to 63 knots).

56. Tropical storms produce large amounts of rain and can cause enough wind and wave activity todamage boats and erode beaches. A tropical storm may occur in any of Earth’s ocean basins in which tropical cyclones are found (North Atlantic, northeast Pacific, central Pacific, northwest and southwest

57. The size and structure of tropical storms are similar to those of the more intense and mature tropical cyclones; they possess horizontal dimensions of about 160 km (100 miles) and winds that are highest at the surface but decrease with altitude. The winds typically attain their maximum intensity at approximately 30–50km (20–30 miles) away from the center of the circulation, but the distinct eyewall that is a characteristic of mature tropical cyclones is usually absent.

58. Typhoon or Hurricane When a storm system has sustained winds of over 74 miles per hour (64 knots), a spiral arrangement of thunderstorms with a low- pressure center is considered a hurricane, or a typhoon. Meteorologists generally use the term “hurricane” for storms in the Atlantic Ocean and the word “typhoon” for those in the Pacific Ocean. Hurricanes are the most dangerous and devastating type of tropical system.

59. A typhoon forms when winds blow into areas of the ocean where the water is warm. These winds collect moisture and rise, while colder air moves in below. This creates pressure, which causes the winds to move very quickly. The winds rotate, or spin, around a center called an eye. The more warm air and moisture there is, the more intense the winds

60. PAGASA Weather Disturbances Symbols

61. Here are the things we need to do for us to be safe in different weather disturbances.  Listen to weather updates and advisories.  Check your house’s condition and make necessary repairs.  Keep your first aid kit in an area where you can easily get it in case of an emergency.

62.  Have enough emergency supplies such as food, water, and clothes for at least 3 days or 1 week.  Have a contact system in place to reach family and friends  Evacuate immediately once asked by the authorities to do so.

64. _____ 2. The first aid kit must be placed in an accessible area in your house. _____ 3. Do not evacuate immediately if you are being told by the rescue team to evacuate. _____ 4. Essential supplies like food and water must not be prepare during a typhoon.

65. _____ 5. Save contacts with your family and friends so that you can access them easily during a typhoon.

66. Directions: During calamities or different weather disturbances coming we need to know the nearest evacuation center so that we can easily evacuate if we are being told so. For your activity, draw a map from your house going to the nearest evacuation center in your community. In this way, it is not difficult anymore for you and your family to evacuate.

67. A weather disturbance is a term used to describe a change in atmospheric conditions or weather patterns. • Tropical depressions are cyclones with winds that gust at 38 miles per hour (33 knots) or less.

68. • Tropical storm when the cyclone’s circulation is more organized and has sustained wind speeds of 39 to 73 miles per hour (34 to 63 knots). • Typhoon has sustained winds of over 74 miles per hour (64 knots),

71. SCIENCE 5 QUARTER 4 WEEK 3 DAY 4 Low-Pressure Area

72. DIRECTIONS: Identify the following statement if it is Tropical Depression, Tropical Storm, or Typhoon. _____________1. It has sustained winds of over 74 miles per hour (64 knots). _____________2. A cyclone with a wind that gust at 38 miles per hour (33 knots) or less

73. _____________3. It has sustained wind speeds of 39 to 73 miles per hour (34 to 63 knots). _____________4. It is the most dangerous and devastating type of tropical system. _____________5. A tropical cyclone that produces large amounts of rain, and can cause enough wind and wave activity to damage boats and erode beaches.

74. Observe the picture below: What is the meaning of L in the picture? Is there a possibility that LPA become a super typhoon?

75. As what the PAGASA forecaster always says that, they are not removing the possibilities that a Low-pressure Area can be a super Typhoon. And the residence should be ready in case it will land fall.

76. Low-Pressure Area (LPA) and High Pressure (HPA) This refers to the weight of the air that is pressing down on Earth. An abrupt change in the air pressure can trigger weather disturbances. Convection, or the rising of warm air and sinking of cold air, explains how a high-pressure area and a low pressure are formed.

77. When cold air sinks, it results in a high-pressure area. Since most of the air is pressing down, the air on the surface becomes dry. The formation of a high-pressure area indicates fair weather since fewer clouds are found in the sky.

78. Warm air rises, less air presses downward, resulting in the formation of a low-pressure area. As the air continuously rises, it will eventually cool, condense, and form clouds. The formation of a low-pressure area indicates the possibility of rain. There is a higher chance of rain when more clouds are formed. An LPA can result in weather disturbances, rains, and strong winds are brought about by low pressure.

79. How do tropical cyclones develop? In a cyclone, the cool air flows to take the place of the rising warm air. As a result, the air current spins. The wind spirals around to the center of the cyclone. This center is called the eye. It is surrounded by bands of clouds and winds. When a cyclone is formed over the tropics. It is called a tropical cyclone. Given that the Philippines is found in the tropics, we experience tropical cyclones.

80. Tropical cyclones that occur within the Philippine Area of Responsibility (PAR) develop in two areas. These areas are in the Pacific Ocean and the West Philippine Sea. A cyclone that originates from the West Philippine Sea moves in an east to northeast direction.

81. The eye is the calm area at the center of the typhoon where the winds are not moving and the clouds are very few. The eyewall is the part of the typhoon that surrounds the calm area. It brings the strongest winds and heaviest rains.

82. A tropical cyclone or typhoon develops when: 1. The air in the upper level of the atmosphere has high humidity to form clouds. 2. The surface temperature of ocean water is more than 26 degrees Celsius.

83. 3. Existing weather disturbance is away from the equator, enabling the Coriolis effect in the Northern Hemisphere to drive the wind to form a spiral pattern. The Coriolis effect makes things (like planes or currents of air) traveling long distances around the Earth appear to move at a curve as opposed to a straight line.

84. DIRECTIONS: Read and analyze each statement. Write the letter of the correct answer before the number. _____1. In _______ pressure systems, air rises in the sea surface. A. High B. Low C. Medium D. None

85. _____2. This pressure system has the potential to bring thunder, lightning, and heavy rain. A. High-pressure system B. Low-pressure system C. Warm front D. Cold front

86. _____3. Which of the following weather conditions is associated with low-pressure air? A. Cloudy, rainy weather B. Cold, sunny weather C. Hot, sunny weather D. The pressure of air does not affect the weather

87. _____4. Which map view best represents the movement of surface air in the Northern Hemisphere around a Low-Pressure system?

88. _____5. Where do tropical cyclones originate? From the low-pressure area in the land From the low-pressure area in the tropical ocean From a high-pressure area over the ocean From high-pressure area over the land

89. Why should we listen to the radio or watch the television for weather forecasts before heading out to do our outdoor activities while, according to PAGASA's weather forecast, a Low Pressure Area is developing inside the Philippine Area of Responsibility?

90. Low-Pressure Area-is an area where there is rising warm air. High-Pressure Area- is an area where there is sinking cool air. A cyclone is a weather disturbance characterized by a large whirling mass of air moving in a counter-clockwise direction. Typhoons are tropical cyclones that occur in Western Pacific and the South China Sea
