Water Cycle and Carbon Cycle Test Practice

Front

What is the water cycle?

Back

The water cycle, also known as the hydrologic cycle, is the continuous movement of water on, above, and below the surface of the Earth. It involves processes such as evaporation, condensation, precipitation, and infiltration.

Front

What is the main source of energy for the water cycle?

Back

The Sun is the main source of energy for the water cycle, driving the processes of evaporation and transpiration.

Front

What is evaporation in the water cycle?

Back

Evaporation is the process by which water changes from a liquid to a gas (water vapor) due to heat from the Sun.

Front

What is condensation in the water cycle?

Back

Condensation is the process by which water vapor cools and changes back into liquid water, forming clouds.

Front

What is precipitation in the water cycle?

Back

Precipitation is any form of water, such as rain, snow, sleet, or hail, that falls from clouds to the Earth's surface.

Front

What role do humans play in the water cycle?

Back

Humans impact the water cycle through activities such as urbanization, deforestation, and pollution, which can alter natural water flow and quality.

Front

What is the carbon cycle?

Back

The carbon cycle is the process by which carbon atoms are recycled through the Earth's ecosystems, involving processes such as photosynthesis, respiration, decomposition, and combustion.

Front

How do plants contribute to the carbon cycle?

Back

Plants absorb carbon dioxide from the atmosphere during photosynthesis, converting it into glucose and releasing oxygen.

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, which is influenced by the carbon cycle.

Front

What are greenhouse gases?

Back

Greenhouse gases are gases that trap heat in the atmosphere, including carbon dioxide (CO2), methane (CH4), and nitrous oxide (N2O).
