Question

1. choose the best answer. how does the sun affect the water cycle? it makes the water disappear. it stops the water from moving. it causes evaporation and precipitation. it speeds up the water’s movement.

Explanation:

To determine how the sun affects the water cycle, we analyze each option:

• "It makes the water disappear" is incorrect because water in the cycle is transformed, not lost.
• "It stops the water from moving" is wrong as the sun drives the cycle, promoting movement.
• "It causes evaporation and precipitation" is accurate. The sun's heat causes evaporation (liquid to gas), and the subsequent cooling (related to solar energy driving atmospheric processes) leads to condensation and precipitation (gas to liquid/solid falling as rain, snow, etc.).
• "It speeds up the water’s movement" is a vague description. The sun's main role is initiating evaporation (a key part of the cycle) and driving the processes that lead to precipitation, not just a general "speeding up" of movement. The most precise and correct description is that it causes evaporation and precipitation.

Answer:

It causes evaporation and precipitation.
