Study Notes

Greenhouse Gases and Heat Trapping

Greenhouse gases play a crucial role in trapping heat in the atmosphere, creating a thermal blanket that warms the Earth's surface.

Characteristics of Greenhouse Gases

Greenhouse gases have a significant impact on climate due to their ability to absorb and re-emit infrared radiation, preventing heat from escaping into space.
Unlike the glass in a greenhouse, which traps heat through physical barriers, greenhouse gases trap heat through their molecular structure.

Molecular Structure of Greenhouse Gases

Greenhouse gas molecules have a unique characteristic that allows them to trap heat: they have three or more atoms, which enables them to vibrate and rotate when absorbing infrared radiation.

Heat Trapping Process

When a greenhouse gas molecule releases heat, it is re-emitted in all directions, some of which is directed back towards the Earth's surface, contributing to the warming effect.
