1.What is the phenomena called Greenhouse effect?

There are some gases that are emitted by our vehicles, factories etc. mostly Carbon dioxide, forms a layer in atmosphere that traps the heat emitted by earth surface and slowly making the climate warmer. This is called the Greenhouse effect.

Due to Greenhouse effect the temperature of earth will raise and some of the countries will become too hot to live and this extra raise in temperature can also cause glaciers to start melting that result in flooding in low-lying countries this whole phenomenon of raise in temperature due to Greenhouse effect is also known as global warming.

A warmer Earth may lead to changes in rainfall patterns, a rise in sea level, and a wide range of impacts on plants, wildlife, and humans.
