Question

1. which of the following plays a key role in moving water from high elevations to lower areas? a. groundwater b. runoff c. condensation d. evaporation

Explanation:

• Groundwater: It is water present beneath the Earth's surface in soil pore spaces and fractures of rock formations. It does not play a key role in moving water from high elevations to lower areas.
• Runoff: Runoff is the flow of water that occurs when excess water from rain, snowmelt, or other sources flows over the Earth's surface. It moves water from higher elevations (like mountains or hills) to lower elevations (like rivers, lakes, or oceans).
• Condensation: It is the process by which water vapor in the air is changed into liquid water. It is part of the water cycle but not directly involved in moving water from high to low elevations.
• Evaporation: It is the process by which water changes from a liquid to a gas or vapor. It is also part of the water cycle but not responsible for moving water from high to low elevations.

Answer:

B. Runoff
