Which of the following is a way humans can impact the water cycle?

• deforestation

• combustion of fossil fuels

• paving new roads

• all of the above

This phase of the water cycle occurs when water that has infiltrated the soil gets absorbed by a plant's roots, and will be released back into the atmosphere through its leaves.

• evapotranspiration

• transpiration

• evaporation

• runoff

Runoff is closely tied to what other stage of the water cycle?

• condensation

• evaporation

• precipitation

• none of the above

Carbon takes millions of years to recycle itself in which carbon cycle?

• geological

• biological

Cutting down large forests (deforestation) can result in:

• little to no changes

• more homes for animals

• less plants to absorb carbon dioxide, a greenhouse gas
