Water 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 clouds.

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 is runoff?

Back

Runoff is the flow of water, usually from rain, that moves across the ground and returns to bodies of water like rivers, lakes, and oceans.

Front

What is infiltration?

Back

Infiltration is the process by which water on the ground surface enters the soil.

Front

What percentage of Earth's water is freshwater?

Back

Only about 3% of all water on Earth is freshwater.

Front

Why is it important to conserve water?

Back

Conserving water is important because it helps protect our environment, ensures a sustainable supply for future generations, and reduces the energy needed for water treatment and distribution.

Front

What is the difference between renewable and non-renewable water resources?

Back

Renewable water resources are those that are replenished naturally, like rivers and lakes, while non-renewable resources are those that do not replenish on a human timescale, like groundwater in certain aquifers.

Front

What is the role of plants in the water cycle?

Back

Plants play a role in the water cycle through a process called transpiration, where they release water vapor into the atmosphere.
