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. 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.
The ozone layer is the layer of the atmosphere that filters the  sun's rays. This layer is located in the upper atmosphere called  the stratosphere.here is no layer in the sun that filters out dangerous rays, but the layer in the earth that filters out said rays is called the ozone layer, also known as the startosphere. â¦ It consists of O3 molecules that break apart under the impact of rays and then re-form to re-create the barrier again.
