Ozone layer

Explanation:

The ozone layer found in the stratosphere is responsible for protecting the earth against harmful radiation.

In the lower atmosphere, the ozone is a pollutant and very harmful to life.

Ozone is an oxygen molecule made up of 3 atoms of oxygen covalently bonded to one another. It usually found in the ozone layer within the stratosphere just above the reaches of the troposphere. Ozone cuts off and absorb harmful ultraviolet rays emanating from the sun. This prevents the earth from being exposed to these solar bursts.

Ozone is not found in the air of the troposphere. Here, it will act as a pollutant.

Air is a mixture of many gases of which ozone is not a part of.

Mantle convection is the process that drives plate tectonics. the theory of plate tectonics states that the crust is divided into plates that float on the semi molten mantle below. the circular motion of the magma as it slowly rises and falls or move though convection cells drags the plates along causing them to move. the heat source in the lamp would represent the earth's core. the core is the source of energy that drives convection in the mantle. the lava represents molten magma under the earth's surface. if the lava lamp had floating pieces they would move as the circular motion of the lava in the lamp as it rises and falls would move them along the surface. these floating pieces would represent pieces of the earth's crust. 

There is a great difference between the windward and leeward side of a mountain. windward and leeward sides are opposites.
