Human Impact on Climate (NEW)

Front

What are greenhouse gases?

Back

Greenhouse gases are gases in Earth's atmosphere that trap heat, contributing to the greenhouse effect. Examples include carbon dioxide (CO2), methane (CH4), and nitrous oxide (N2O).

Front

How do greenhouse gases affect Earth's temperature?

Back

Greenhouse gases trap heat in the atmosphere, which warms the planet, leading to global warming.

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 fossil fuels?

Back

Fossil fuels are natural resources formed from the remains of ancient plants and animals, including coal, oil, and natural gas.

Front

What is the difference between renewable and non-renewable resources?

Back

Renewable resources can be replenished naturally over time (e.g., solar energy, wind), while non-renewable resources exist in finite amounts and cannot be replaced (e.g., fossil fuels).

Front

What is the impact of human activities on climate change?

Back

Human activities, such as burning fossil fuels and deforestation, increase greenhouse gas emissions, leading to climate change.

Front

What are some effects of climate change on ecosystems?

Back

Climate change can lead to habitat loss, altered species distributions, and increased extinction rates among plants and animals.

Front

How does deforestation contribute to climate change?

Back

Deforestation reduces the number of trees that can absorb CO2, increasing the concentration of greenhouse gases in the atmosphere.

Front

What is the role of the ocean in climate regulation?

Back

Oceans absorb a significant amount of CO2 and heat, helping to regulate Earth's climate, but they can also become warmer and more acidic due to climate change.

Front

What is the greenhouse effect?

Back

The greenhouse effect is the process by which certain gases in Earth's atmosphere trap heat, keeping the planet warm enough to support life.
