Science 7 - LAND and SEA BREEZE and its Characteristics

Science 7 Lesson. land and sea breeze

1. DECODE ME!

2. My challenge for you is to solve the mystery and find out what is the reason why we have different weather disturbances in our country. Solve the mystery word by guessing the hidden words of the number codes. (Coding example 1=A, B=2…) DECODE ME!

6. INTERACTIONS IN THE ATMOSPHERE: The Sea And Land Breeze, The ITCZ And The Philippine Monsoons

7. MELCs Account for the occurrence of land and sea breezes, monsoons, and intertropical convergence zone. (S7ES-IVf-7)

8. THE SEA AND LAND BREEZE

9. SEA BREEZE At day time, the land surface heats up faster than the water. Therefore, the air above the land surface becomes warmer than the air above the water or the body of water. As this warm air over the land rises, the cold air over the body of water flows over the land surface to replace the rising warm air. This moving air or wind that blows from the body of water onto the land is called a sea breeze.

10. SEA BREEZE

11. LAND BREEZE Land breeze, on the other hand occurs during nighttime . Land surface cools down faster than the water surface. The air above the water stays warmer than the air over the land. The warm air over the water rises and the colder air above the land flows onto the water to replace the warm rising air. This flow of air from the land onto the water is called a land breeze.

12. LAND BREEZE

13. THE SEA AND LAND BREEZE SEA BREEZE Occurs during hot, summer days LAND BREEZE At day time, the land surface heats up faster than the water. Occurs during nighttime Land surface cools down faster than the water surface. The air above the land surface becomes warmer than the air above the water or the body of water The air above the water stays warmer than the air over the land.

The warm air over the water rises and the colder air above the land flows onto the water to replace the warm rising air.

17. Illustrating Land Breeze and Sea Breeze Direction : Using the diagram below, draw the movement of wind using arrows to show land breeze and sea breeze then give a brief explanation about it.

18. Illustrating Land Breeze and Sea Breeze

19. Explaining Sea and Land Breeze Answer the questions carefully. This will help you in finding clues to solve the mysteries of sea and land breeze and how both can make the wind transfer from one place to another. 1. What is the sea breeze? 2. What is Land breeze? 3. What is the relationship of the sea and land breeze to the temperature of an area?

20. Sea Breeze Directions: Arrange the following in chronological order to show the correct process of land and sea breeze. Number it from 1-4. _____ During the day, the land surface heats up faster than the water surface. _____ The air above the land is warmer than the air above the ocean. Now, recall that warmer air is lighter than cooler air. _____ As a result, warm air rises. _____ As the warm air over the land is rising, the cooler air over the ocean goes over the land surface to replace the rising warm air.

21. Land Breeze Directions: Arrange the following in chronological order to show the correct process of land and sea breeze. Number it from 1-4. _____ The cool breeze from the land is called a land breeze. _____ The air on the water becomes warmer, less dense and begins to rise. _____ Cold and denser air over the land begins to transfer to the water surface to replace the warmer rising air. _____ The air on land quickly cools while the air on the water keeps its warmth.
