The Layers of the Atmosphere

Thermosphere*The thermosphere is the fourth layer in the atmosphere.*The thermosphere is where the space shuttle orbits.*The thermosphere is the layer with the auroras fom the North and South Pole.*Height: Begins at 85 km above Earth*Within this layer, ultraviolet radiation causes ionization.

The Layers of the AtmosphereBy: Vipisha Pazhanivel

Troposphere* Lowest layer in the atmosphere.*Height: 7- 20 km above sea level*Nearly all of the water vapor and dust particles in the atmosphere are in the troposphere.*All clouds are found in the troposphere*Air is warmest at the bottom of the troposphere near ground level.

Mesosphere* The mesosphere is the third layer in the atmosphere.*Meteors burn up in the mesosphere.*As you get higher up in the mesosphere, the temperature gets colder.*Height: About 50 km above Earth's surface*Weather balloons cannot fly high enough to reach the mesosphere.

Exosphere* The exosphere is the last layer of the atmosphere which is above the thermosphere.*Air in the exosphere is extremely thin.*It is almost the same as the airless void of outer space.*It starts at an altitude of about 250-500 km, but its height depends on the amount of solar activity.

Stratosphere*The stratosphere is the second layer in the atmosphere.*Ozone is an unusual type of molecule mostly found in the stratosphere.*Many aircraft fly in the stratosphere.*Height: 12 kilometers*A rare type of electrical discharge occurs in the stratosphere
