Carbon Cycle Review

What is the greenhouse effect?

• The warming of Earth's atmosphere and surface because of greenhouse gases such as carbon dioxide absorbing energy from the sun

• Flow of carbon from the atmosphere to the lithosphere

• The atmosphere turning green because of too much carbon dioxide

• Colder temperatures as carbon dioxide reflects sun's rays

What is carbon?

• A type of atom found in all living things

• Process by which plants use sun's energy to make glucose

• Any part of the land, sea, and atmosphere containing living organisms

• A gas in the atmosphere

What is the Keeling curve?

• A graph showing the continuous change in concentrations of atmospheric carbon dioxide

• A type of baseball pitch

• The long-term carbon cycle, such as burial and cementation

• The flow of carbon from the hydrosphere to the biosphere
