Greenhouse gases

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

The greenhouse effect is the process by which greenhouse gases trap heat from the Sun in the Earth's atmosphere, keeping the planet warm.

Global warming refers to the long-term increase in Earth's average surface temperature due to human activities, primarily the emission of greenhouse gases.

1. Increase in Earth's temperatures 2. Increase in ocean temperatures 3. Rise in sea levels.

False. Some radiation is reflected back into space.

Sunlight warms the Earth's surface, which is essential for life.

Greenhouse gases warm the surface of the Earth and help it stay at a comfortable, warm average temperature.

Carbon dioxide is a greenhouse gas produced by burning fossil fuels, deforestation, and respiration.

Methane is a potent greenhouse gas that is released during the production and transport of coal, oil, and natural gas, as well as from livestock and other agricultural practices.

Nitrous oxide is a greenhouse gas that comes from agricultural and industrial activities, as well as during combustion of fossil fuels and solid waste.
