what are greenhouse gases and why are they a problem?
gases that cool the earth and help plants grow
gases released from plants and trees that take all of oxygen
gases that clean the air and reduce pollution
gases released from burning fossil fuels that trap heat and cause warming

Explanation:

Greenhouse gases are mainly released from burning fossil fuels (like coal, oil, gas). They have the property of trapping heat in the Earth's atmosphere. This heat - trapping effect is similar to how a greenhouse works (hence the name). When there is an excessive amount of these gases (due to increased fossil fuel burning in modern times, for example, in power generation, transportation), it causes the Earth's average temperature to rise, leading to global warming. Global warming has various negative impacts such as melting ice caps, rising sea levels, more extreme weather events (like stronger hurricanes, more intense heatwaves and droughts in some areas).
