ATMOSPHERE OF THE EARTHThe Earth's atmosphere is more than just the air we breathe. It's also a buffer that keeps us from being peppered by meteorites, a screen against deadly radiation, and the reason radio waves can be bounced for long distances around the planet.

FIVE MAJOR LAYERS

TroposphereStratosphereMesosphereThermosphereExosphere

TROPOSPHERE

Thetroposphereis the lowest layer of Earth's atmosphere and site of all weather on Earth. Thetroposphereis bonded on the top by a layer of air called the tropopause, which separates thetropospherefrom the stratosphere, and on bottom by the surface of the Earth.

STRATOSPHERE

Thestratosphereis the second major layer ofEarth's atmosphere, just above thetroposphere, and below the mesosphere. It isstratifiedin temperature, with warmer layers higher up and cooler layers farther down. This is in contrast to the troposphere near the Earth's surface, which is cooler higher up and warmer farther down.

MESOSPHERE

Themesosphereis the layer of theEarth's atmospherethat is directly above thestratopauseand directly below themesopause. In the mesosphere temperature decreases as the altitude increases. The upper boundary of the mesosphere is the mesopause, which can be the coldest naturally occurring place on Earth with temperatures below 130K (226F; 143C).

THERMOSPHERE

Thethermosphereis the layer of the Earth's atmosphere directly above the mesosphere and directly below the exosphere. Within this layer, ultraviolet radiation causes photoionization/photodissociation of molecules present.

EXOSPHERE

The exosphere is the uppermost layer, where the atmosphere thins out and merges with interplanetary space. It is located directly above thethermosphere.

Relationship between Climatic Elements, Controls and Types

Elements of Climate:

Whether we have hot or cold seasons, lots of rain or very little is determined by how temperature, moisture, wind, and air pressure mix in Earth's atmosphere. Climate Controls

TheKppen Climate Classification Systemis the most widespread system used to classify the climates of places on our planet. The system was developed German climatologist and amateur botanist Wladimir Kppen (1846-1940) who divided the world's climates into several major categories based upon general temperature profile related to latitude.Classification or Types of Climatesby Koppen Classification
