cycles of matter

Front

What is condensation?

Back

Condensation is the process where water vapor in the air cools down and changes back into liquid water, forming dew or clouds.

Front

What is the nitrogen cycle?

Back

The nitrogen cycle is the process in which nitrogen is converted between its various chemical forms, allowing it to be used by living organisms.

Front

What is evaporation?

Back

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

Front

Why is nitrogen fixation important?

Back

Nitrogen fixation is important because atmospheric nitrogen is unusable by plants and animals, and it must be converted into a form they can use.

Front

How does carbon move through an ecosystem?

Back

Carbon moves through an ecosystem via food chains, where it is transferred from plants (like grass) to herbivores (like lions) when they eat them.

Front

What is the water cycle?

Back

The water cycle is the continuous movement of water on, above, and below the surface of the Earth, including processes like evaporation, condensation, and precipitation.

Front

What role do plants play in the carbon cycle?

Back

Plants absorb carbon dioxide from the atmosphere during photosynthesis, converting it into organic matter.

Front

What is precipitation?

Back

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

Front

What is the phosphorus cycle?

Back

The phosphorus cycle is the process by which phosphorus moves through the lithosphere, hydrosphere, and biosphere, essential for plant and animal growth.

Front

What is transpiration?

Back

Transpiration is the process by which water is absorbed by plant roots and then released as water vapor through pores in leaves.
