4. Take a look outside your window, is it rainy or sunny? is it cloudy or hot? When you look out the window, you’re seeing what the weather is today.

5. The weather condition is affected by the different elements that change the atmosphere. It refers to the clouds, wind, temperature, pressure, humidity, precipitation, sunshine, and visibility . Climate and weather are different concepts, though they are related.

6. Climate , on the other hand, is more than just warm or cool days. Climate describes the typical weather conditions in an entire region for a very long time.

7. The following are elements of the atmosphere that might affect weather and climate:

8. 1. Air temperature is the measure on how hot or cold the air is. At high temperature, the molecules in the air move faster and water evaporates faster.

9. 2. Air pressure is the measure on how heavy the air is over a unit of area. With higher air pressure, the weight of air above us becomes heavier. This indicates fair weather. With lower pressure, the air molecules moves toward the atmosphere, this signal a stormy weather.

10. 3. Amount and type of precipitation forms of droplets of water (drizzle, shower, downpour) or solidified water (snow, ice and hail).It is the condensation of water vapor and its deposition on the earth’s surface

11. 4. Wind speed and direction. Wind is the uneven distribution of temperature and pressure in the atmosphere. Air moves from an area of high pressure to that of a low pressure. Wind that blows over bodies of water are cooler and moist , while wind that travels over landmasses is warmer and dry.

12. 5. Types of cloud. With very warm air temperature, water vapor condenses to form clouds. The more evaporation takes place, the more saturated the clouds will become and form rain clouds.

13. 6. The amount of water vapor in the air is known as humidity. Dry air has low humidity, while moist air has high humidity
