The water cycle& Fresh water (HW#7)

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 stages like evaporation, condensation, precipitation, and runoff.

Front

What is evaporation?

Back

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

Front

What is condensation?

Back

Condensation is the process by which water vapor cools and changes back into liquid water, forming droplets, such as dew on grass.

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 runoff?

Back

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

Front

What percentage of Earth's water is fresh water?

Back

Approximately 3% of Earth's water is fresh water.

Front

What role do plants play in the water cycle?

Back

Plants absorb water from the soil and release water vapor into the atmosphere through a process called transpiration.

Front

What is groundwater?

Back

Groundwater is water that is stored underground in soil and rock layers, and it can flow into rivers and lakes.

Front

How does the sun influence the water cycle?

Back

The sun provides the energy needed for evaporation, driving the water cycle by turning liquid water into vapor.

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.
