water cycle and atmosphere

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 causes water to change its state (solid, liquid, gas)?

Back

Temperature causes water to change its state. For example, heating water turns it into steam (gas), while cooling it can turn it into ice (solid).

Front

What is the main energy source that drives the water cycle?

Back

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

Front

What are clouds formed from?

Back

Clouds are formed when water vapor in the air cools and condenses into tiny water droplets.

Front

What layer of the atmosphere do the Northern Lights occur in?

Back

The Northern Lights occur in the thermosphere.

Front

What comes after the stratosphere in the layers of the atmosphere?

Back

The mesosphere comes after the stratosphere.

Front

What is evaporation?

Back

Evaporation is the process where liquid water turns into water vapor (gas) due to heat.

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

Front

What is the troposphere?

Back

The troposphere is the lowest layer of the atmosphere where weather occurs and where we live.
