Question

1. the sun affects the water cycle by:

____a. making clouds in the sky.
____b. cooling down water in oceans.
____c. providing heat that turns water into vapor.
____d. stopping the process of transpiration in
plants.

1. what is a front?

____a. a large body of air that stays in one pla
____b. the boundary between two different ai
masses
____c. a body of air that has the same
temperature and humidity
____d. a layer of warm air above cold air

Explanation:

Question 8

• Option A: Clouds form from water vapor condensation, not the Sun directly making clouds. Eliminate A.
• Option B: The Sun heats ocean water, not cools it. Eliminate B.
• Option C: The Sun's heat causes evaporation (water to vapor), a key part of the water cycle. This is correct.
• Option D: The Sun’s energy drives transpiration (plants releasing water vapor), it doesn't stop it. Eliminate D.

• Option A: A large body of air with uniform properties is an air mass, not a front. Eliminate A.
• Option B: A front is the boundary between two different air masses (with different temp/humidity). This matches the definition.
• Option C: This describes an air mass, not a front. Eliminate C.
• Option D: A temperature inversion (warm air over cold) is not a front. Eliminate D.

Answer:

C. Providing heat that turns water into vapor.
