The mesosphere is a layer of Earth's atmosphere. The mesosphere is directly above the stratosphere and below the thermosphere. It extends from about 50 to 85 km (31 to 53 miles) above our planet.
The ozone layer, in the stratosphere, is where about 90% of the ozone in the Earth system is found. But ozone makes up only one to ten out of every million molecules in the ozone layer. There isn't much of it, but ozone is powerful, able to block the most harmful radiation.
Resource Type: Information
Radio waves have the longest wavelengths of all the types of electromagnetic radiation.
The stratosphere is a layer of Earth's atmosphere. It is the second layer of the atmosphere as you go upward. The troposphere, the lowest layer, is right below the stratosphere. The next higher layer above the stratosphere is the mesosphere.
The thermosphere is a layer of Earth's atmosphere. The thermosphere is directly above the mesosphere and below the exosphere.
The troposphere is the lowest layer of Earth's atmosphere. Most of the mass (about 75-80%) of the atmosphere is in the troposphere. Most types of clouds are found in the troposphere, and almost all weather occurs within this layer.
Ultraviolet (UV) "light" is a form of electromagnetic radiaiton. It carries more energy than the normal light we can see.
Visible light is the most familiar part of the electromagnetic spectrum because it is the energy we can see.
Waves of energy are described by their wavelength.
