How Landforms and Bodies of Water Affect Typhoons within the PAR

What is the Philippine Area of Responsibility (PAR)?

• A land-based area in the Philippines

• The region monitored by PAGASA for tropical cyclones

• An area where typhoons cannot enter

• A restricted zone for air traffic

How does the Pacific Ocean affect typhoon formation near the Philippines?

• It cools down typhoons, reducing their intensity

• It provides the warm, moist air that fuels typhoon formation

• It prevents typhoons from forming due to its calm waters

• It has no effect on typhoons

What temperature does the ocean need to be for a typhoon to form?

• Above 26°C

• Below 20°C

• Exactly 24°C

• Any temperature

Which landform can slow down a typhoon as it passes over the Philippines?

• Valley

• Plateau

• Mountain

• Plain

What effect do mountain ranges have on typhoons?

• They increase the typhoon's strength

• They slow down and weaken typhoons

• They cause typhoons to move faster

• They have no impact on typhoons

What is the rain shadow effect in relation to typhoons?

• Rain falls more intensely on the leeward side of mountains

• Rain falls only over bodies of water

• The windward side of mountains receives more rain, while the leeward side remains drier

• All areas receive equal rainfall during typhoons

What usually happens to a typhoon when it hits land?

• It gains strength

• It weakens due to lack of moisture

• It maintains its strength

• It splits into multiple storms

Why are coastal areas in the Philippines heavily affected by typhoons?

• Coastal areas are more elevated

• Typhoons always weaken before reaching coasts

• They are the first to be hit and experience strong winds and storm surges

• They are not affected as much as inland areas

Which of the following helps fuel and intensify typhoons near the Philippines?

• Cold winds from the mountains

• Warm ocean waters

• Cooler air from inland areas

• Deserts

How do valleys influence typhoons that pass over them?

• They block the typhoon entirely

• They slow down the typhoon's movement

• They allow winds and rainfall to pass through more intensely

• They reduce rainfall from typhoons
