4. Due to the Earth’s rotation, tropical cyclones in the northern hemisphere rotate in opposite directions as to the

cyclones in the southern hemisphere. Tropical cyclones in the north rotate ______.

A. Clockwise B. Horizontally C. Counterclockwise D. Vertically

5. The following statements explain why the Philippines is frequently visited by tropical cyclones, EXCEPT:

A. Philippines is beside the Pacific Ocean C. Philippines is very close to the equator

B. Philippines is made up of thousands of islands D. Philippines has a tropical climate

6. “Tropical cyclones entering the Philippine Area of Responsibility (PAR) are called typhoons.” This statement is:

A. True, because the local term for a tropical cyclone in our country is typhoon.

B. True, because tropical cyclones entering the PAR are already considered as typhoons.

C. False, because a tropical cyclone entering the PAR is categorized according to its maximum sustained

winds.

D. False, because all tropical cyclones in our country are super typhoons due to their strength.

7. Which of the following is the correct sequence of events of tropical cyclone formation?

I. Warm ocean water heats up the air above it and warm air rises.

II. Heat makes the air rise even more and the air in the surroundings keep coming in. The air starts to spin.

III. Water vapor in the rising water condenses and heat is given off.

IV. The rising warm air results in a low-pressure area and the air in the surroundings move towards it.

A. I, II, III, IV B. IV, III, II, I C. I, IV, III, II D. I, III, II, IV

8. What happens to a typhoon if it moves over land?

A. It gains strength and its winds become more violent.

B. It loses strength and weakens.

C. It maintains the maximum sustained winds of planets.
D. Landforms had no effect on typhoons

9. The following are probable reasons for a sudden change in the direction of a typhoon within the PAR,

EXCEPT:

A. A low- pressure area is near the country

B. A high- pressure area is near the country

C. It is guided by the bodies of water within the country

D. The presence of land formations such as mountain ranges at its path

10. Which of the following statements about air pressure is correct?

A. Air pressure is dependent on the density of the air. C. Air pressure increases with elevation.

B. Air pressure is independent of the density of air. D. Air pressure is greatly affected by gravity.

11. The following conditions favor typhoon formation EXCEPT:

A. Warm waters in the tropical regions of the oceans C. Landforms

B. Presence of a low-pressure area D. Coriolis effect

12. A cyclone is a storm formed over which body of water?

A. Pacific Ocean B. Atlantic Ocean C. Indian Ocean D. Mediterranean Sea

13. Which of these effects generally occurs as the result of a warm air mass and a cooler air mass converging at

Earth’s surface?

A. The sky becomes clear. C. Cloud formation decreases.

B. Winds die down. D. Stormy weather patterns develop.

14. A phenomenon referred to by the trapping of heat energy from the sun, causing the earth’s temperature to

rise

A. global warming B. greenhouse effect C. Coriolis effect D. ozone depletion

15. Measures the amount of moisture in the air

A. barometer B. anemometer C. rain gauge D. hygrometer
