Greenhouse Effect

Front

What is the greenhouse effect?

Back

The greenhouse effect is the warming of the Earth's atmosphere caused by the trapping of heat by greenhouse gases, which prevents heat from escaping into space.

Front

What are greenhouse gases?

Back

Greenhouse gases are gases in the Earth's atmosphere that trap heat, including carbon dioxide (CO2), methane (CH4), nitrous oxide (N2O), and fluorinated gases.

Front

What human activities contribute to the greenhouse effect?

Back

Human activities such as burning fossil fuels, deforestation, and industrial processes contribute to the increase of greenhouse gases in the atmosphere.

Front

What is the role of carbon dioxide in the greenhouse effect?

Back

Carbon dioxide absorbs infrared radiation emitted from the Earth's surface, contributing to the greenhouse effect and warming the atmosphere.

Front

What are CFCs and their impact on the environment?

Back

Chlorofluorocarbons (CFCs) are man-made compounds that deplete the ozone layer and are potent greenhouse gases, contributing to global warming.

Front

How does deforestation affect the greenhouse effect?

Back

Deforestation reduces the number of trees that can absorb CO2, leading to higher concentrations of greenhouse gases in the atmosphere.

Front

What is the significance of the Keeling Curve?

Back

The Keeling Curve is a graph that shows the increase in atmospheric CO2 levels over time, indicating the impact of human activities on climate change.

Front

What are some natural sources of greenhouse gases?

Back

Natural sources of greenhouse gases include volcanic eruptions, wildfires, and respiration from plants and animals.

Front

What is the difference between climate change and the greenhouse effect?

Back

The greenhouse effect is a natural process that warms the Earth, while climate change refers to long-term changes in temperature and weather patterns, often exacerbated by human activities.

Front

What can individuals do to reduce greenhouse gas emissions?

Back

Individuals can reduce greenhouse gas emissions by using energy-efficient appliances, reducing car travel, recycling, and using renewable energy sources.
