Atmosphere Layers

Atmosphere Layers:

This atmosphere layer is super heated from the sun radiation because it's the closest to the sun. This atmosphere is made up with small amounts of helium, hydrogen, and other gases.The temperature range is 150 degrees and higher since it takes most of the suns radiation. The density/ altitude range of the exosphere 500-520 km. Scientist don't consider this layer to be an actual layer since this layer is made up of other gases and so little of it too. This layer is the less densest layer in the layers.

This layer is the hottest layer. Sattelites and space shuttles revolve the planet in this layer. A Electromagnetic Phenomenon occurs here, it's called the Aurora Borealis. The Temperature range here is 100 degree's too 150 degree's. The air that is in here is nitrogen and oxygen but it's also very hot so human life couldn't live here. The density in this layer is 90km too 1,000km.

This layer is the coldest layer. Meteors disingrates here in this area. Nitrogen and Oxygen are in this layer along with others. The density in this atmosphere is very low. the temperatures range from -100 degrees C. This layer cools as you get higher. there are barely any molecules in this layer. This is the middle layer. "Meso" stands for middle.

In this layer only large jets can fly at the bottom of this layer. Weather balloons collect data in this layer also. The ozone is on the top of the stratosphere which protects the earth from deadly radiation. Air molecules are very thin here, you need a space suit to survive here. The density in this layer is 11km to about 47km. The temperature here is 273 degrees to 0 degrees C. This layer is made up of Nitrogen and Oxygen.This layer contains the ozone.

In this layer life is here and weather occurs. The temperature gets colder with altitude. Take Mt. Everest for example. The higher you get in Mt. Everest the colder it gets and it makes it more difficult to breath. The air molecules are the most dense here. This layer is heated by the surface of the Earth. The temperature range is 62 degrees to -60 degrees. The density in this range decreases with height. This layer is the densest layer. The altitude in this layer is 4-12 miles high. This layers air composition is filled with Nitrogen, Oxygen, and other gases. The exact percentages are, Nitrogen(78%), Oxygen(21%), and other gases(1%).






Heat Transfer

The last heat transfer is Convection. Convection occurs in a rise and fall motion. Example: Macoroni rises and falls when cooking in the boiling water. This is where density comes to play. When the object is cold it sinks, it then warms up when it's at the bottom of the stove. It warms up and rises up again. It does this until finally it's cooked. This transfer is under the troposphere

Another heat transfer is Conduction. It transfers heat by an object touching another. Example: Your hand touching a stove (don't do that) that would be conduction. So it's heat transfer that transfers by touch. This transfer is under the troposphere.

One heat transfer is Radiation. Radiation is divergence of heat to travel across the room. Example: Sitting infront of a fire. The heat it traveling to you by air. The sun is another example because its traveling to you by electromagnetic waves.This heat transfer is under the tropsphere.
