Chapter 14: Climate and 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 activities, primarily the emission of greenhouse gases.

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

What is Deforestation?

Back

Deforestation is the clearing or thinning of forests by humans, which contributes to increased carbon dioxide levels in the atmosphere.

Front

What role do aerosols play in climate?

Back

Aerosols can cool the climate by reflecting sunlight away from the Earth's surface.

Front

What is the Theory of Continental Drift?

Back

The Theory of Continental Drift states that continents were once part of a single landmass (Pangaea) and have since drifted apart.

Front

What are temperate zones?

Back

Temperate zones are regions of Earth with moderate temperatures, typically found between the tropics and polar regions.

Front

What is the impact of burning fossil fuels on climate?

Back

Burning fossil fuels releases large amounts of greenhouse gases, contributing to global warming.

Front

What are renewable energy sources?

Back

Renewable energy sources are energy sources that are replenished naturally, such as solar, wind, and hydroelectric power.

Front

What is energy efficiency?

Back

Energy efficiency refers to using less energy to provide the same service or achieve the same outcome.

Front

What is the greenhouse effect?

Back

The greenhouse effect is the process by which greenhouse gases trap heat in the atmosphere, keeping the Earth warm.
