ATMOSPHERE
we have been ko cocooned and product was a colorless ,odorless and tasteless blanket of gases that is known as atmosphere display blanket around is about 700 km the gravitational force of the earth holds it together the atmosphere consists of several layer.
COMPOSITION
MS wire has some fixed component it contains 78% Nitrogen 21% Oxygen and 0.9% argon the other gases are carbon dioxide hilium hydrogen and Ozone etc.
water vapour particles of smoke Pollen dust and emissions from factories and vehicles are under constituent of the atmosphere.
STRUCTURE
the atmosphere has several let the basic on which the distinction between the layers have been made a temperature changes chemical composition movement and density it is the densest near the surface of the earth and slowly things out as it go higher 99% of the total mass of the atmosphere is said to be live within 30 km of the Earth surface it is not possible to try fixed boundary line and define where it ends.
be considered atmosphere stretch to about 1000 km above the surface of the earth.
TROPOSPHERE
this is the lowest layer of the atmosphere its thickness rise from 8 km above the poles of 18 km over the equator.the temperature decrease by 1 Degree Celsius for every 165 m.
the word troposphere is derived from the Greek term propose meaning turning on mixing.it contains 75% of the atmospheric gases and large amounts of water vapour and dust.the topic is bare act like a blanket protection the Earth from becoming too hot during the day and too cold at night.this is the densest layer and the nearest to the surface of the Earth which is the warmest.about 80% of the total mass of the atmosphere is said to be contained in the layer.dad observed the sun heats and radiates its back to the atmosphere all weather phenomena like water vapour cloud formation rhinestone take place in this layer.the topo pass is the thin layer between the troposphere and stratosphere.
STRATOSPHERE
this layer state to 50 km of the Earth surface phenomena occur here.there is little water vapour and condition or not turbulent this is the safest zone for flying jet aircraft it has the maximum presentation of ozone and hence this layer is known as ozonosphere.
it is all it protects us from the harmful ultraviolet rays of the sun leading to an increase in the temperature in this year at about 50 km the temperature decrease again this part of store space called storo pauseand from here I start the next layer of the atmosphere.
MESOSPHERE
this layer stage between 50 to 80 km above the Earth's surface the temperature decreases with increasing altitude and deep down to -100 ⁰ degree Celsius the John has the lowest temperature in the atmosphere.
the density of air is very thing me jo pass mark the in the major square and the beginning of thermosphere.this layer usually slow the metorate and burns them.
THERMOSPHERE
the temperature in this layer rise to around 1500 degree Celsius it extends from 80 km to more than 600 km above the Earth this layer contains electrically charged particles card and these particles reflects radio waves back to the surface of the earth enabling long distance Radio Communication.
EXOSPHERE
it is an outermost layer of the atmosphere which merge with the outer space the gravitational pull here is very big the density is very low as only traces of gases are found here.
IMPORTANCE OF THE ATMOSPHERE
every component of The Invisible blanket plays an important role-
1-it provide us with nitrogen which is required to keep password fertile it helps in the growth of Living Organism.
2-it gives us air for breathing
3-plants use carbon dioxide for photosynthesis.
4-the Ozone in the atmosphere protect the earth from the harmful effect of the ultraviolet and infrared rays of the Sun.
5-it helps to maintain the heat balance by absorbing and disturbing the heat during daytime and not allowing the heat to escape at night.
6-it helps in circulation of water vapour and formation of cloud and rain.
7-it protects the Earth from meteorites.
8-it is very useful for communication
9-it is composed of various gases which are essential for life to survive.
atmospheric pollution is increasing day by day it is leading to various health problems.global warming is causing a hole in the ozone layer.we need to be alert to this problem and files based on protecting the atmosphere.
WIND
bending moment 8 ka this is something that all of us can feel if anyone is a please all gentle Wind blowing do not you like to go and play outside.
Darshan hits of some places more than other and this lead to a difference in air pressure.high temperature match time smakes the air creating an area of low pressure code make the air Singh trust increasing the pressure.
code make the air Sink increasing the pressure from an area of high pressure to low pressure zone.
this moment is called wind.
the wind current is stronger if the difference in pressure is higher.
due to the rotation of the earth will get deployed to the right in the Northern hemisphere and it the left the southern hemisphere.
BIOSPHERE
the base region Limited and define Geography area bare land water and air meet and Where are living in dwell.
for life to exist it is essential for all the three rims lithosphere Hydrosphere And Atmosphere to come together.
in other words there is a combination of the three square life forms and interact with each other at which the environment.this is what make our planet so special in the solar system.
for instance human belong to the animal kingdom but largely depend on the plant Kingdom for their food this is an example of interependence.
unfortunately human beings are responsible for disturbing the balance which has been preserved By Nature for millions of years over population has increased the demand for living space to forest been cut down to build house
similarly in order to bring more area under construction for agricultural Industries homes for other plant and animal species has been destroyed.
