Question

1. gravity affects the water cycle by:

____a. starting the evaporation of water.
____b. helping water vapor go up in the air.
____c. stopping clouds from forming in the sky.
____d. bringing rain and snow down to the
ground.

1. are these true or false statements?

write t or f.
____ warm air is less dense and rises.
____ ocean currents affect regional climates.
____ warm water brings cooler temps.
____ the ocean helps regulate earths
temperature.
____ the majority of earths freshwater is easily
accessible.

Explanation:

Question 17

• Option A: Evaporation is caused by heat (like from the sun), not gravity. So A is incorrect.
• Option B: Gravity pulls things down, while water vapor rising is due to its low density (warmer, less dense air). Gravity doesn't help vapor go up. So B is incorrect.
• Option C: Clouds form when water vapor condenses; gravity doesn't stop cloud formation. So C is incorrect.
• Option D: Rain and snow (precipitation) fall to the ground because of gravity. This matches how gravity affects the water cycle. So D is correct.

Warm air expands, so its density decreases. Less dense air rises (e.g., hot air balloons work on this principle). So this is true.

Ocean currents (like the Gulf Stream) can warm or cool regions. For example, the Gulf Stream keeps Western Europe warmer. So this is true.

Answer:

D. Bringing rain and snow down to the ground.
