The atmosphere is a big blanket of air around the Earth. It is very important to Biodiversity. This is mainly because it holds in air, which is gravely required for respiration among living beings.
Earth's atmosphere is important for several
reasons: it supports the exchange of life-
sustaining gases, filters sunlight, regulates
temperature and even plays a role in the water
cycle. The atmosphere contains five distinct
layers. Its first layer, the stratosphere, is closest
to Earth and serves as the activity spot for
weather production and cloud formation. It
contains an ozone layer, which prevents
dangerous sun rays from passing through clouds
and modifies temperature, letting life exist.
