Light,Climate Change, Greenhouse effect Flashcard

Front

What is the significance of studying carbon isotopes in climate change?

Back

Carbon isotopes can track how much carbon in the atmosphere comes from fossil fuels.

Front

What role do plants play in the carbon cycle?

Back

Plants absorb CO2 from the atmosphere during photosynthesis.

Front

When did the global temperature start to increase significantly?

Back

Around 1970.

Front

Which type of electromagnetic radiation has the longest wavelength?

Back

Radio waves.

Front

What causes small fluctuations in yearly carbon dioxide levels?

Back

Seasonal changes in photosynthesis rates by plants.

Front

Define the greenhouse effect.

Back

The greenhouse effect is the warming of the Earth's surface due to the trapping of heat by greenhouse gases in the atmosphere.

Front

What are greenhouse gases?

Back

Greenhouse gases are gases that trap heat in the atmosphere, including carbon dioxide (CO2), methane (CH4), and nitrous oxide (N2O).

Front

How does deforestation impact the carbon cycle?

Back

Deforestation increases CO2 levels in the atmosphere by reducing the number of trees that can absorb CO2.

Front

What is the carbon cycle?

Back

The carbon cycle is the process by which carbon is exchanged between the Earth's atmosphere, land, and oceans.

Front

What is the primary source of carbon emissions from human activities?

Back

Fossil fuel combustion.
