2. What makes the air move?
When the air becomes warm, it
rises.
What will happen to the air in the
surrounding?
It will move towards the place
where warm air is rising
3. Which warms up faster – the land
or water?
The land heats up faster than
water.
Which cools down faster – the
land or water?
Land lose heat faster the water in
the sea.
10. Low Pressure Area
Low Pressure Area is a place
where warm air is rising.
High Pressure Area
High Pressure Area is a place
where cool air is sinking.
11. What are the two types of
monsoons?
1. Northeast Monsoon (Amihan):
From October to March amihan
comes from the northeast and moves
towards the south.
It passes over the Pacific Ocean
before it reaches the Philippines,
bringing rain to the eastern part of the
Philippines.
12. What are the two types of
monsoons?
2. Southwest Monsoon (Habagat):
From July to September habagat
comes from the southwest and
moves towards the north.
It passes over the Indian Ocean
and South China Sea before it arrives
in the country, bringing rain to the
western portion of the Philippines.
14. What is Intertropical Convergence
Zone?
It is a place where winds in the
tropics meet, rise and form
clouds, resulting in
thunderstorms during certain
times of the year.
15.
16. As warm air over equatorial
areas rises, the air in the
surroundings will move in. Air
from north of the equator and
south of the equator will then
meet or converge at the place
where warm air is rising.
18. 1. What happens when air is heated?
a. It rises.
b. It stays in place.
c. It spreads in all directions.
d. It moves toward a lower
elevation.
19. 2. Which warms up faster, land or
water?
a. Land
b. Water
c. Both warm up at the same rate.
d. Rate of warming varies;
depends on weather conditions.
20. 3. What happens to the surrounding
air as warm air rises?
a. Moves in all directions
b. Moves to a higher altitude
c. Moves away from the rising air
d. Moves toward the place where
warm air rises
21. 4. In what direction do winds blow?
a. From the northeast to the
southwest
b. From the southwest to the
northeast
c. From low pressure areas to high
pressure areas
d. From high-pressure areas to low-
pressure areas
22. 5. Which of the following does NOT
describe the amihan?
a. Brings lots of rain
b. Brings cold weather
c. Comes around July to
September
d. Comes from the northeast and
moves southward
23. 6. What is FALSE about ITCZ?
a. It results in thunderstorms.
b. It occurs in countries near the
equator.
c. It occurs in the Philippines all
year round.
d. It is a place where winds in the
tropics meet, rise, and form clouds.
24. Draw arrows to show the direction of
wind during a sea breeze.
25. Draw arrows to show the direction of
wind during a land breeze.
Editor's Notes
The air pressure is not the same everywhere
In places where warm air is rising, the air pressure is low.
Are there any questions about air pressure?
Now we can discuss about monsoons…
Why do they bring rains? Both the amihan and habagat bring rain to the Philippines. This is because the winds pass over bodies of water which supply a lot of moisture. The amihan passes over the Pacific Ocean before it reaches the Philippines, bringing rain to the eastern part of the Philippines. The habagat passes over the Indian Ocean and South China Sea (West Philippine Sea) before it arrives in our country, bringing rain to the western portion of the country.
Why does the wind move from north to south? Because there is a low-pressure area in the south (near Australia) at that time.
The northeast monsoon or amihan is cold because it comes from
cold areas, such as Siberia and Mongolia, in the Asian continent.
What happens when air is heated?
a. It rises.
b. It stays in place.
c. It spreads in all directions.
d. It moves toward a lower elevation.
15. Which warms up faster, land or water?
a. Land
b. Water
c. Both warm up at the same rate.
d. Rate of warming varies; depends on weather conditions.
As warm air over equatorial areas rises, the air in the surroundings
will move in. Air from north of the equator and south of the equator will then
meet or converge at the place where warm air is rising.
