Earths water cycle

Front

What is the water cycle?

Back

The water cycle is the continuous process by which water moves through the environment, including evaporation, condensation, precipitation, and collection.

Front

Why are oceans a major part of the water cycle?

Back

Because they are large bodies of salt water that fresh water can be evaporated from.

Front

What is evaporation?

Back

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

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 happens during precipitation?

Back

Precipitation occurs when water droplets in clouds combine and fall to the ground as rain, snow, sleet, or hail.

Front

What is an aquifer?

Back

An aquifer is a geological formation that can store and transmit groundwater, providing a source of freshwater.

Front

What is salinity?

Back

Salinity is the measure of the amount of salt dissolved in water, typically expressed in parts per thousand.

Front

Where would you find the lowest salinity in the ocean?

Back

In areas near melting glaciers.

Front

What effect does melting polar ice caps have on sea levels?

Back

Melting polar ice caps cause sea levels to rise.

Front

What is the role of the sun in the water cycle?

Back

The sun provides the energy needed for evaporation, driving the water cycle.
