Flashcard Review: Atmospheric Layers & The Water Cycle

Front

What is evaporation?

Back

Evaporation is the process by which water changes from a liquid to a gas, usually due to heat from the sun.

Front

What is the main energy source that causes evaporation?

Back

The sun is the main energy source that causes evaporation.

Front

Which layer of the atmosphere contains ozone molecules?

Back

The stratosphere contains ozone molecules that absorb ultraviolet radiation.

Front

What is the role of ozone in the atmosphere?

Back

Ozone absorbs harmful ultraviolet radiation from the sun, protecting living organisms on Earth.

Front

What form of energy causes water to change from a liquid to a gas?

Back

Heat is the form of energy that causes water to change from a liquid to a gas.

Front

Where is temperature typically the coldest on a mountain?

Back

Temperature is typically the coldest at the topmost part of the mountain.

Front

What is Earth's main source of heat and light?

Back

The sun is Earth's main source of heat and light.

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 evaporation, condensation, and precipitation.

Front

What is condensation?

Back

Condensation is the process by which water vapor in the air 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 clouds to the Earth's surface.
