Video notes: Carbon cycle, fossil fuels, and greenhouse gases

Vocabulary flashcards covering the main concepts from the video notes on carbon cycle, human impact, fossil fuels, and greenhouse gases.

Main human CO2-emitting activities

Burning fossil fuels for electricity, heating, and transport.

The carbon cycle with human impact

The carbon cycle plus human impact—the portion students need to learn.

Fossil fuel reserves

Natural deposits of carbon-based fuels (coal, oil, natural gas).

Main CO2-emitting activities (cement and slash-and-burn)

Burning fossil fuels, cement production, and slash-and-burn agriculture emit CO2.

Burning timber releases carbon dioxide

Burning timber releases CO2 into the atmosphere when used in buildings and furniture.

Carbon versus CO2 (notes claim)

Notes state 'Carbon, not as CO2'.

Timber burning and global warming claim (notes)

Notes claim that burning timber does not contribute to global warming.

CO2 and plant growth claim (notes)

Notes claim the more CO2, the better plants thrive.
