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 troposphere is the most interesting layer of the atmosphere. It is below the stratosphere. Weather happens in the troposphere. That is because the troposphere is the only layer that has enough water vapor to have clouds, which drop rain and snow.Some planes fly near the top of the troposphere.The troposphere is the most chaotic layer of the atmosphere; it is also the only one that can support life.eather happens in the troposphere.
