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…)

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.

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.

18. 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.

20. 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?

21. 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.

22. 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.
