Troposphere The troposphere starts at the ground and extends about 30,000 feet to 56,000 feet up. It is the layer where all weather takes place. It is heated mostly by the warm surface of the earth, meaning that the higher you go in the troposphere, the colder it gets.
Stratosphere The stratosphere is the next layer up in the atmosphere. This is the layer planes fly in, so that they are above weather. This layer has the ozone in it, ozone is a gas that absorbs harmful radiation and keeps it from reaching ground level. The ozone heats up as it absorbs, so the higher you go the hotter it gets. The stratosphere is from the top of the troposphere to 170,000 feet above sea level. At the top of the Troposphere, temperatures are around
Mesosphere The next layer is the mesosphere, stretching from the top of the stratosphere to about 280,000 feet up. The higher you go in this layer, the colder it gets. At the top of the Mesosphere temperatures can reach -150 degrees. In this layer, most meteorites and other debris from space burn up while entering the atmosphere.
Thermosphere The thermosphere is the next layer up. The Thermosphere absorbs harmful radiation coming from this sun. Absorbing this causes the Thermosphere to heat up, sometimes up to 2,700 degrees. It spans about 300 miles.
How layers Differ The layers are all very different. They have different roles in protecting life on earth and different properties. The troposphere is a smaller layer where weather occurs. Weather doesn’t occur in any other layer. The stratosphere is a little bigger in height than the troposphere and is the only layer where ozone molecules absorb and protect us from radiation, in the troposphere for example, the ozone molecules are a dangerous gas. The mesosphere is the layer that burns up meteors because the meteors collide with the gas molecules and the friction of the collision burns up matter from space. The thermosphere is by far the largest layer, and it is responsible for absorbing harmful radiation (not the same kind as the stratosphere). Every layer is different and has
