Greenhouse Effect and Global Warming Quiz

Study Notes

Greenhouse Gases and the Atmosphere

Greenhouse gases, such as carbon dioxide, methane, and water vapor, trap heat in the Earth's atmosphere, maintaining a habitable temperature.
The greenhouse effect is a natural process that warms the planet, allowing life to thrive.

Impact on Earth's Temperature

The greenhouse effect increases the Earth's average temperature by about 33°C, making it suitable for life.
Without the greenhouse effect, the planet's average temperature would be around -18°C, making it inhospitable.

Contributors to the Greenhouse Effect

Carbon dioxide (CO2) is the most abundant greenhouse gas, responsible for about 65% of the warming effect.
Methane (CH4) is the second-most potent greenhouse gas, with a global warming potential 28 times higher than CO2.
Water vapor (H2O) is the most abundant greenhouse gas in terms of volume, but its concentration is largely controlled by temperature.

Ozone Layer Function

The ozone layer (O3) protects the Earth's surface from harmful ultraviolet (UV) radiation, which can damage living organisms.
The ozone layer is essential for life on Earth, as it allows plants to undergo photosynthesis and supports the food chain.

Essential Gases for Life

Methane, carbon dioxide, and water vapor are essential for life on Earth, as they provide the necessary conditions for photosynthesis, respiration, and other biological processes.
These gases help regulate the Earth's temperature, allowing life to thrive in a narrow range of temperatures.
