Ch 7 - Water Cycle and Weather

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 again through evaporation, condensation, and precipitation.

Front

What drives the water cycle?

Back

The sun is the primary energy source that drives the water cycle by providing heat that causes evaporation.

Front

What is evaporation?

Back

Evaporation is the process where liquid water turns into water vapor and enters the atmosphere.

Front

What is condensation?

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 that falls from clouds to the Earth's surface, including rain, snow, sleet, and hail.

Front

What is wind?

Back

Wind is the movement of air caused by differences in air pressure, and it plays a key role in moving weather systems.

Front

What is fog?

Back

Fog is a type of cloud that forms at ground level, consisting of tiny water droplets suspended in the air.

Front

What are clouds?

Back

Clouds are visible masses of condensed water vapor floating in the atmosphere, formed by condensation.

Front

What is the difference between rain and snow?

Back

Rain is liquid water droplets that fall when temperatures are above freezing, while snow is frozen water crystals that fall when temperatures are below freezing.

Front

What is sleet?

Back

Sleet is a form of precipitation that consists of small ice pellets, formed when raindrops freeze before reaching the ground.
