The document discusses atmospheric phenomena such as breezes, monsoons, and the intertropical convergence zone. It explains that breezes are winds that blow over short distances and are caused by the unequal heating of the Earth's surface. Monsoons are seasonal wind systems characterized by reversal of wind directions. The Philippines experiences the northeast monsoon from October to March and the southwest monsoon from July to September. The monsoons affect farming in the Philippines both positively, through providing water for irrigation, and negatively, through potential flooding.

4. Warm Air
Surrounding Air
From the illustration, answer the following guide questions:
Q1: Is the movement of
warm air upward?
Answer: YES

5. Warm Air
Surrounding Air
From the illustration, answer the following guide questions:
Q2: Why is it that the
warm air rises?
Answer: Warm air
rises because it is less
dense than cold air
from its surrounding.

6. Warm Air
Surrounding Air
From the illustration, answer the following guide questions:
Q3: How will you describe
the movement of
surrounding air?
Answer: The
surrounding air move
towards where the
warm air is rising.

7. Warm Air
Surrounding Air
From the illustration, answer the following guide questions:
Q4: Compare the direction of
movements between
surrounding air and warm air.
Answer: The surrounding
air move downward
(sinking) while warm air
move upward (rising).

8. The air moves
upward or rises
when heated.

9. When air is heated, its
molecules gain enough energy
to move around faster and
spread out. When a mass of air
takes up more space, it
becomes less dense than the
surrounding air molecules.
Hence, warm air rises above
the cold and denser air below
it.

10. • The rising warm air
creates a low pressure
which pulls in cool air to
replace the rising air.
• Low pressure is
associated with rising air
as air particles leave the
surface. As the cool air
descends, it creates a
high pressure at the
surface. Air that moves
from places of high
pressure to low pressure
make WINDS.

Q2: Why is there a difference between the movement of air during
daytime and nighttime?
Answer: There is a difference in the direction of the movement of air
because of the unequal temperature of air in our surroundings.

Q3: What do you call these movements of air in pictures A and B?
Answer: The movement of air in the pictures are called breezes.

18. -a wind that blows over a short distance.
-caused by the UNEQUAL heating of Earth’s
surface within a small region.
Example:
1.Sea breeze
2. Land breeze

20. During the day, the land heats up faster than the water in
the sea.

21. During the night, the land and sea will both cool
down. But the land will lose heat faster than the
water in the sea.

22. • Wind system that is characterized by seasonal reversal of
direction.
• Sea and land breezes over a large region that change
direction with seasons.
• Characterized by a dramatic seasonal change in the
direction of the prevailing winds over a large area. This
change in the direction of the prevailing winds brings about
changes in the amount of rainfall and leads to the distinct
wet and dry seasons.

23. Study and analyze the
following maps in figure 10
and 11. It show the air
pressure and directions of
winds in different parts of
the world. The letter L
indicates the areas with low
pressure, H for with high
pressure areas and
arrowheads indicate for the
direction of wind.

Answer:
Northeast monsoon

28. Q4: In what direction do air of
different pressures move?
Why do you think so?
Q5: From what direction do
the winds blow near the
Philippines in July?
Q6: What type of monsoon
does the country (Philippines)
experience in July? Image retrieved from: H6oA6.jpg (700×332) (imgur.com)

29. Q4: In what direction do air of different pressures move? Why do you think so?
Answer: Air always move
from high to low
pressure area, because if
the temperature of air is
high it will rise thus
creating the area low in
pressure, then cold air
from high-pressure area
will move towards the
low-pressure area to
replace the rising air.

34. The agency responsible for assessing and forecasting weather, flood, and other conditions
that are essentials for the safety of the people.

35. Appears as a band of
clouds consisting of
showers, with occasional
thunderstorms, that
encircles the globe near
the equator.

36. The place where winds in
the tropics meet or converge.
The equator is warmer than
the North and South poles, the
cooler air is drawn towards the
equator to replace the rising warm
air. Vapor pressure condenses as
air rises and cools in the ITCZ,
forming clouds and rain. This is
where monsoon rainfall occurs.

39. YOUR TURN!
How the monsoons affect the Filipino farmers.
Give some monsoons’advantages and disadvantages
in farming.
Disadvantage of monsoon:
1. Rain water creates flood situation
everywhere and hence that kills thousands of
people and animals.
2. Excess rainfall forces migration of the
people living in the area closer to the river
catchment.
3. Also rain water causes excessive load on
our drainage system.

40. YOUR TURN!

Give some monsoons’advantages and disadvantages
in farming.
Advantage of monsoon:
1. Seasonal monsoon rains can also
provide freshwater for drinking and
crop irrigation.
2. Brings lower temperatures.
3. Allows plants to grow, eventually
fills streams, rivers, lakes, and ponds,
and rain adds humidity to the air.
