Atmospheric Factors Affecting Climate-elijah

Atmospheric Factors Affecting Climate
By:Elijah

    Introduction

The atmosphere is a very unique part of our planet. Our planets atmosphere is the thing that gives our planet extra warmth. The atmosphere has many layers to protect the planet from many things as well. without the atmosphere the planet would be unable to support life. In all the atmosphere is a very important resource.

    Basic Makeup of the Atmosphere

There are many different layers of the atmosphere, each having special qualities. The first layer is the troposphere, this is the layer where all living thing are and where weather occurs. Next is the stratosphere in this layer is the home place of ozone witch protects us from harmful U. V. rays. Third is the Mesosphere, this layer protects the planet from meteoroids. Finely is the Thermosphere, in this layer it is the warmest and where space shuttles fly. 


There are many gases that are used to make up our air that are in large amounts and some in the smallest. The most
abundant gas in our air is called nitrogen. The most important gas in our air is oxygen. Without oxygen our planet could not harbor life. the very last gas in our air can be summed up as other gases because all together they only make up 1% of our air. Some of the gases include Argon, Carbon dioxide, Neon, and Helium which reside in only trace amounts.



      Earth can keep itself warm by using many different methods. First the planet uses green House gasses to warm itself and keep warmth in. Second it could relief only on the suns rays with our atmosphere to bounce theme around in the  planet. In all there are many ways to heat the planet.



Threats to Earth

There are many threats to the earth like green house gases. Green house gasses destroy ozone and heat the planet more than usual.

 


The green house effect

    the green house effect is when heat gets radiated back and forth.

 

There are three major types of green house gasses. First is London type green house gasses. Next is photochemical green house gasses. Finally is acid rain which is a very dangerous type of smog. Green house gasses have a warming effect on the planet. they lock more heat in our atmosphere. We should care because the earth can become very harmful to people.

 

Ozone

    Ozone is the combination of three air atoms. ozone helps us by deflecting dangerous U.V. rays away from us. Ozone can hurt us to when inhaled. so ozone is very important.

 

Ozone depletion is very threatening to the planet. the ozone layor is an important layor in the stratosphere. ozone thining occurs in the poles the reson this is is thought to be because of green house gasses.

 

    In all ozone must be repaired and green house gasses should be slowed or attempted to be stoped.
