Water Distribution and Cycle

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, such as rain, snow, sleet, or hail, that falls from the atmosphere to the Earth's surface.

Front

What is surface runoff?

Back

Surface runoff is the flow of water that occurs when excess rainwater, meltwater, or other sources flow over the Earth's surface.

Front

What percentage of Earth's water is found in the oceans?

Back

About 97% of Earth's water is found in the oceans.

Front

What is groundwater?

Back

Groundwater is water that is stored underground in soil and rock layers, and it is a significant source of fresh water.

Front

How does precipitation contribute to groundwater?

Back

Precipitation seeps through pores and cracks in the ground, replenishing groundwater supplies.

Front

What is the most abundant source of freshwater on Earth?

Back

Lakes are the most abundant supply of liquid surface water that is not salty.

Front

What role does sunlight play in the water cycle?

Back

Sunlight provides the energy needed for evaporation to occur, driving the water cycle.
