Earth's Atmosphere and The Ozone Layer
Manage episode 358783142 series 3454205
Our atmosphere is made up of several distinct layers including, but not limited to, the troposphere, the stratosphere, the mesosphere, and the thermosphere.
The troposphere is the lowest layer of the atmosphere and is the layer closest to the Earth's surface. It is the layer where most of the weather and clouds form and is the warmest layer of the atmosphere. It contains around 78% of the atmosphere's mass, and is heated by the Earth's surface. The pressure in the troposphere decreases as altitude increases, and this causes the temperature to drop.
The stratosphere is the second layer of the atmosphere, located above the troposphere. This layer is heated by the ozone layer, which absorbs a lot of the Sun's ultraviolet radiation. The pressure in the stratosphere is relatively constant, and the temperature increases with altitude.
The mesosphere is the third layer of the atmosphere, located between the stratosphere and the thermosphere. This layer is very cold, and temperatures drop to around -90 °C at its highest point. The mesosphere is home to some of the highest clouds in the atmosphere, and it is also the layer where most meteors burn up.
The thermosphere is the fourth and highest layer of the atmosphere. This layer is very thin and is not visible from the ground. It contains very little air, and temperatures increase with altitude. The thermosphere is home to the aurora borealis and some of the highest man-made objects, like satellites.
