Water Cycle & Distribution of Water on Earth

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 happens during evaporation?

Back

Evaporation is the process where liquid water turns into water vapor due to heat from the sun.

Front

What is condensation in the water cycle?

Back

Condensation is the process where water vapor 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 the hydrosphere?

Back

The hydrosphere refers to all of Earth's water, including oceans, rivers, lakes, and water vapor in the atmosphere.

Front

Where does most evaporation occur on Earth?

Back

Most evaporation occurs from the oceans, which cover about 71% of the Earth's surface.

Front

What role do plants play in the water cycle?

Back

Plants contribute to the water cycle through transpiration, where they release water vapor into the atmosphere from their leaves.

Front

How does temperature affect evaporation rates?

Back

Higher temperatures increase evaporation rates 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 polar ice caps in the water cycle?

Back

The polar ice caps store a significant amount of Earth's freshwater and their melting can impact sea levels and global climate.
