Light,Climate Change, Greenhouse effect Flashcard

Front

What is visible light?

Back

Visible light is the portion of the electromagnetic spectrum that can be seen by the human eye, and it includes all the colors of the rainbow.

Front

Why are carbon isotopes important in climate change studies?

Back

Carbon isotopes help track how much carbon in the atmosphere comes from fossil fuels, providing insight into human contributions to climate change.

Front

What process adds carbon to the atmosphere?

Back

Fossil fuel combustion adds carbon to the atmosphere.

Front

What is a Positive Feedback Loop?

Back

A Positive Feedback Loop is a process where an initial change causes further changes that amplify the original effect, such as an ad getting more views leading to more exposure.

Front

What is a major reason for the increase in carbon dioxide levels?

Back

Burning fossil fuels is a major reason for the increase in carbon dioxide levels.

Front

What is 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, methane, and nitrous oxide.

Front

How does photosynthesis affect carbon dioxide levels?

Back

Photosynthesis reduces carbon dioxide levels by converting it into oxygen and glucose.

Front

What role do oceans play in carbon cycling?

Back

Oceans absorb carbon dioxide from the atmosphere, helping to regulate global carbon levels.

Front

What is climate change?

Back

Climate change refers to significant changes in global temperatures and weather patterns over time, largely driven by human activities.
