Question 1:

What is the primary source of water vapor for the Earth's water cycle?

Explanation: The primary source of water vapor for the Earth's water cycle is evaporation, where water changes from a liquid state to a gaseous state.

Question 2:

Which process involves the release of water vapor from plants into the atmosphere?

Explanation: The process that involves the release of water vapor from plants into the atmosphere is transpiration. It is a crucial part of the water cycle and contributes to the overall movement of water.

Question 3:

Which of the following factors does NOT affect the rate of evaporation?

Explanation: Atmospheric pressure does not directly affect the rate of evaporation. However, temperature, humidity, and wind speed are important factors that influence the rate of evaporation.

Question 4:

What happens to water vapor as it rises in the atmosphere?

Explanation: As water vapor rises in the atmosphere, it cools and condenses into clouds. This process is responsible for the formation of clouds and eventually leads to precipitation.

Question 5:

Which process involves the conversion of ice directly into water vapor?

Explanation: The process that involves the conversion of ice directly into water vapor is called sublimation. It occurs when the temperature and pressure conditions are suitable for skipping the liquid phase.
