|Can you tell me why the atmosphere is important?
|Question Date: 2014-07-26|
The atmosphere is important for many reasons! One
reason is that the earth's atmosphere acts as an
insulating layer that protects the earth's surface
from the intense light and heat of the sun. The
atmosphere protects us from UV and other short
wavelength light that would otherwise do a lot of
damage to the DNA of living organisms. Without the
atmosphere, it would get really hot in the day
time, and extremely cold at night!
The atmosphere is also important because it
contains oxygen, which we and other living
organisms breathe. It also acts as a medium of
transport for various chemicals, including, but
not limited to, water (in the form of rain, snow,
steam, etc), carbon dioxide and oxygen (for
cycling of these chemicals between plants and
animals), and nitrogen (which helps plants grow).
There are also other biogeochemical cycles
(cycling of different chemicals) between the land
masses, the oceans, and the atmosphere that are
important for the various kinds of ecosystems
around the world!
These are only a few of the examples of why the
atmosphere is important, but I hope this helps you
see why it is important to protect our atmosphere!
The atmosphere is important for many reasons.
Before we talk about why it is important we should
define what the atmosphere is. The atmosphere is
the layer of air that surrounds a planet. Earth
has an atmosphere that is just right for humans,
animals, and plants to live in. The gases in the
atmosphere act like a blanket keeping our planet
warm plus the atmosphere contains oxygen something
we (humans and animals) all need to breathe.
Many planets in our solar system have a
atmosphere. Venus for example has such a thick
atmosphere most of the sun's energy gets trapped
making the surface of Venus 864 degrees
Fahrenheit! That is hotter than an oven! Mars also
has an atmosphere but it is too thin making the
surface of Mars -80 degrees Fahrenheit! Plus the
atmospheres of Venus and Mars do not contain the
oxygen we all need to breathe.
Our atmosphere allows just enough of the sun's
energy back into space so that we do not get to
hot like Venus or too cold like Mars. If Earth had
no atmosphere, apart from having no air to
breathe, the surface of the Earth would be 0
These are just two of the reasons why are
atmosphere is important. The atmosphere contains
the warmth we all need to survive, the oxygen we
all breathe, and carries the rain we all need.
Without our atmosphere life as we know it would
cease to exist.
The atmosphere is the air that we breathe, and
contains all our weather. Life on Earth could not
exist without it.
Thank you for your question! Earth's atmosphere
is not empty. It is mostly gas, which we call
"air," and it is held in place because of Earth's
gravity. Some of the gas is oxygen. Many living
things, including humans, need oxygen to breathe.
The gases in the atmosphere also protect us from
harmful solar rays, but not completely, which is
why we often wear sunscreen. The gases trap heat,
which the earth naturally produces. Without an
atmosphere, the surface of the earth would be
very, very cold. The atmosphere also burns up
meteors entering from outer space. The moon does
not have an atmosphere, and so it is constantly
hit with large meteors. These are just some of the
reasons that the atmosphere is important.
