It is also defined by physicists as 'ionized matter'. This is the plasma of physics. Don't confuse it with 'biological plasma' which is a colourless jellylike liquid in our blood. All matter is composed of atoms which are 'neutral'.
The atmosphere consists of 4 layers: the troposphere, stratosphere, mesosphere, and thermosphere. Figure A shows the placement of the different layers of the atmosphere and how the temperature changes with height as you go from the ground up to space.The troposphere is the lowest layer of the atmosphere.This is the layer where we live and where weather happens. Temperature in this layer generally decreases with height. The boundary between the stratosphere and the troposphere is called the tropopause.he troposphere is the lowest layer of the atmosphere.

The ozone layer or ozone shield is a region of Earth's stratosphere that absorbs most of the Sun's ultraviolet radiation. It contains high concentrations of ozone in relation to other parts of the atmosphere, although still small in relation to other gases in the stratosphere. The ozone layer contains less than 10 parts per million of ozone, while the average ozone concentration in Earth's atmosphere as a whole is about 0.3 parts per million. The ozone layer is mainly found in the lower portion
