Greenhouse gases absorb radiation from the EARTH and reradiate back toward the EARTHwhich help to maintain a normal temperature range in the Earth.
Explanation:
Greenhouse gases are gases that are capable to of absorbing infrared radiations that are emitted from the Earth's surface and reradiating back to the Earth which contributed to the greenhouse effects. Examples of greenhouse gases are carbondioxide, methane and water vapour. Others are ozones, flourinated gases, nitrous oxides e.t.c.
The green house gases has lead to climate changes in the Earth by trapping heat, the contribute to respiratory diseases by smog and air pollution. Greenhouse gases concentrations are high during warm seasons and low during cold seasons.
