Water Cycle & Greenhouse Effect

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 is evaporation?

Back

Evaporation is the process by which liquid water turns into water vapor, usually due to heat from the sun.

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

Front

What is runoff?

Back

Runoff is the flow of water, from rain or melting snow, that moves across the ground and returns to bodies of water.

Front

What are greenhouse gases?

Back

Greenhouse gases are gases in the Earth's atmosphere that trap heat, such as carbon dioxide, methane, and water vapor.

Front

What is the greenhouse effect?

Back

The greenhouse effect is the warming of the Earth's surface due to the trapping of heat by greenhouse gases in the atmosphere.

Front

Which human activity contributes most to carbon emissions?

Back

Burning fossil fuels contributes the most to carbon emissions globally.

Front

What is the second most abundant gas in the atmosphere?

Back

Oxygen is the second most abundant gas in the atmosphere, after nitrogen.

Front

True or False: All radiation from the Sun is absorbed by the Earth.

Back

False. Not all radiation from the Sun is absorbed; some is reflected back into space.
