Chapter 21: Climate Review

Front

What is the greenhouse effect?

Back

The greenhouse effect is a natural warming of both Earth's lower atmosphere and Earth's surface caused when heat is trapped in the atmosphere by certain gases.

Front

What gases contribute to the greenhouse effect?

Back

Greenhouse gases include carbon dioxide (CO2), methane (CH4), nitrous oxide (N2O), and water vapor.

Front

What is the relationship between carbon dioxide levels and global temperatures?

Back

As carbon dioxide levels increase, global atmospheric temperatures also increase.

Front

What is a humid tropical climate characterized by?

Back

Humid tropical climates are characterized by the absence of winters.

Front

Which natural processes affect climate?

Back

Natural processes that affect climate include solar activity, volcanic eruptions, and ocean circulation.

Front

What is the impact of human activities on greenhouse gas levels?

Back

Human activities, such as burning fossil fuels and deforestation, increase greenhouse gas levels in the atmosphere.

Front

What is the significance of the term 'climate change'?

Back

Climate change refers to significant changes in global temperatures and weather patterns over time, primarily due to human activities.

Front

How do volcanic eruptions affect climate?

Back

Volcanic eruptions can affect climate by releasing ash and gases into the atmosphere, which can cool the Earth temporarily.

Front

What is the role of ocean circulation in climate?

Back

Ocean circulation helps distribute heat around the planet, influencing climate patterns.

Front

What is the difference between weather and climate?

Back

Weather refers to short-term atmospheric conditions, while climate refers to long-term average weather patterns in a region.
