Water Cycle

Front

What is evaporation?

Back

Evaporation is the process where liquid water turns into water vapor (gas) on Earth's surface, primarily due to heat from the Sun.

Front

How does the Sun's energy affect evaporation?

Back

The Sun's energy speeds up water molecules, causing them to break their bonds and escape into the air as vapor.

Front

What is transpiration?

Back

Transpiration is the process by which water vapor leaves a plant and enters the atmosphere.

Front

Define biosphere.

Back

The biosphere is the regions of Earth that contain all living things, including plants, animals, and microorganisms.

Front

What is the hydrosphere?

Back

The hydrosphere includes all the water on Earth, including oceans, rivers, lakes, and water vapor in the atmosphere.

Front

What role does condensation play 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

Explain the term 'water cycle'.

Back

The water cycle is the continuous movement of water on, above, and below the surface of the Earth, involving processes like evaporation, condensation, and precipitation.

Front

What is the significance of the Sun in the water cycle?

Back

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

Front

How does water return to the Earth's surface after evaporation?

Back

Water returns to the Earth's surface through precipitation, which occurs when condensed water vapor falls as rain or snow.
