7.6 - 3 Human Activities and Global Climate Change

Front

What is the main cause of global warming?

Back

The main cause of global warming is the increase in greenhouse gases, such as carbon dioxide, in the atmosphere due to human activities like burning fossil fuels and deforestation.

Front

Define carbon footprint.

Back

A carbon footprint is a measure of how much carbon dioxide and other greenhouse gases are emitted by an activity, industry, community, or individual.

Front

What are greenhouse gases?

Back

Greenhouse gases are gases in the Earth's atmosphere that trap heat, including carbon dioxide, methane, and nitrous oxide.

Front

What is climate change?

Back

Climate change refers to long-term changes in temperature, precipitation, and other atmospheric conditions on Earth.

Front

How does deforestation contribute to climate change?

Back

Deforestation contributes to climate change by reducing the number of trees that can absorb carbon dioxide, leading to higher levels of greenhouse gases in the atmosphere.

Front

What is the difference between weather and climate?

Back

Weather refers to short-term atmospheric conditions, while climate refers to long-term patterns and averages of weather in a particular area.

Front

What role do fossil fuels play in climate change?

Back

Fossil fuels, such as coal, oil, and natural gas, release large amounts of carbon dioxide when burned, contributing significantly to climate change.

Front

What is the greenhouse effect?

Back

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

Front

What are some effects of global warming?

Back

Effects of global warming include rising sea levels, more extreme weather events, and changes in ecosystems and wildlife.

Front

What is the significance of the Paris Agreement?

Back

The Paris Agreement is an international treaty aimed at limiting global warming to below 2 degrees Celsius by reducing greenhouse gas emissions.
