Key Concepts

Greenhouse Effect

The greenhouse effect is a natural process wherein certain gases in the Earth's atmosphere trap heat from the sun. This trapped heat warms the planet's surface, making it capable of sustaining life. When the concentration of these gases increases, it can lead to an enhanced greenhouse effect, which contributes to global warming and climate change.

Greenhouse Gases

Greenhouse gases are components of the atmosphere, such as carbon dioxide, methane, and water vapor, that have the ability to absorb and emit infrared radiation. Their presence regulates Earth's temperature by trapping heat, but an excess of these gases from human activities can intensify the greenhouse effect and disrupt the climate balance.

Infrared Radiation

Infrared radiation is a type of electromagnetic radiation that is emitted naturally by the Earth's surface as it absorbs solar energy. This form of radiation is absorbed by greenhouse gases, which then re-emit the energy, keeping the lower atmosphere warmer than it would be otherwise. This mechanism is central to understanding how energy is retained in the Earth’s atmospheric system.
