5.8B The Water Cycle Review

Front

What is the water cycle?

Back

The water cycle is the continuous process by which water moves from the Earth's surface to the atmosphere and back, involving processes like evaporation, condensation, and precipitation.

Front

What is evaporation?

Back

Evaporation is the process by which water changes from a liquid to a gas, usually due to heat from the sun.

Front

What is condensation?

Back

Condensation is the process by which water vapor in the air cools and changes back into liquid water, forming droplets.

Front

What is precipitation?

Back

Precipitation is any form of water that falls from the atmosphere to the Earth's surface, including rain, snow, sleet, and hail.

Front

What role does the sun play in the water cycle?

Back

The sun provides thermal energy that causes water to evaporate from oceans, lakes, and rivers, initiating the water cycle.

Front

What is runoff?

Back

Runoff is the flow of water, from rain or melting snow, that moves over the ground and returns to bodies of water like rivers and oceans.

Front

How does temperature affect evaporation?

Back

Higher temperatures increase the rate of evaporation because heat provides energy for water molecules to escape into the air.

Front

What is the difference between weather and climate?

Back

Weather refers to short-term atmospheric conditions, while climate is the long-term average of weather patterns in a specific area.

Front

What is the significance of the water cycle for ecosystems?

Back

The water cycle is essential for replenishing freshwater sources, supporting plant and animal life, and maintaining ecological balance.

Front

What is transpiration?

Back

Transpiration is the process by which plants release water vapor into the air from their leaves, contributing to the water cycle.
