Layers of the Atmosphere & Water Cycle

Front

What are the layers of the atmosphere in order from closest to farthest from Earth's surface?

Back

Troposphere, Stratosphere, Mesosphere, Thermosphere, Exosphere

Front

What is formed when water vapor condenses?

Back

Clouds

Front

What role does the Sun play in the water cycle?

Back

The Sun provides the energy for evaporation and transpiration, making the water cycle possible.

Front

What is the ionosphere?

Back

A region of the thermosphere that contains a high concentration of ions and free electrons, important for radio communication.

Front

What two gases make up 99% of Earth's atmosphere?

Back

Nitrogen and Oxygen.

Front

What is the primary function of the Troposphere?

Back

It is where weather occurs and where most of the Earth's air is found.

Front

What is the Stratosphere known for?

Back

It contains the ozone layer, which absorbs and scatters ultraviolet solar radiation.

Front

What happens during evaporation in the water cycle?

Back

Water changes from a liquid to a gas (water vapor) due to heat from the Sun.

Front

What is precipitation in the water cycle?

Back

Any form of water, liquid or solid, that falls from clouds and reaches the ground, such as rain, snow, sleet, or hail.

Front

How does transpiration contribute to the water cycle?

Back

It is the process by which water is absorbed by plants and then released as water vapor into the atmosphere.
