200

What is the term for a change of matter from a liquid to a gas

Evaporation

200

How does water move from the earth’s surface to the atmosphere

evaporation

200

This human activity accelerates the release of carbon dioxide by clearing forests and burning trees

Deforestation

400

how does sulfur cycle through Earth's systems

(1 example)

volcanic activity, absorption, and decomposition.

500

What are isotopes

Atoms with the same protons but different neutrons

500

This process by bacteria converts ammonia into nitrates, making nitrogen available to plants

Nitrification

500
