Climate Change Flashcard Remediation

Front

What is climate change?

Back

Climate change refers to significant changes in global temperatures and weather patterns over time. While climate change is a natural phenomenon, human activities, especially the burning of fossil fuels, have accelerated these changes.

Front

What is the greenhouse effect?

Back

The greenhouse effect is the process by which certain gases in the Earth's atmosphere trap heat, preventing it from escaping back into space, thus warming the planet.

Front

What are greenhouse gases?

Back

Greenhouse gases are gases that contribute to the greenhouse effect by absorbing infrared radiation. Key examples include carbon dioxide (CO2), methane (CH4), and nitrous oxide (N2O).

Front

How do human activities contribute to climate change?

Back

Human activities, such as burning fossil fuels, deforestation, and industrial processes, increase the concentration of greenhouse gases in the atmosphere, leading to enhanced greenhouse effect and global warming.

Front

What is the role of carbon dioxide in climate change?

Back

Carbon dioxide is a major greenhouse gas that traps heat in the atmosphere. Its levels have increased significantly due to human activities, contributing to global warming.

Front

What is the impact of deforestation on climate change?

Back

Deforestation reduces the number of trees that can absorb CO2, increasing the concentration of greenhouse gases in the atmosphere and contributing to climate change.

Front

What is global warming?

Back

Global warming refers to the long-term increase in Earth's average surface temperature due to human-induced emissions of greenhouse gases.

Front

What are some effects of climate change?

Back

Effects of climate change include rising sea levels, more extreme weather events, loss of biodiversity, and changes in agricultural productivity.

Front

What is the significance of the Keeling Curve?

Back

The Keeling Curve is a graph that shows the increase of carbon dioxide in the atmosphere over time, illustrating the impact of human activities on climate change.

Front

What is the difference between weather and climate?

Back

Weather refers to short-term atmospheric conditions in a specific place at a specific time, while climate refers to the long-term average of weather patterns in a region.
