The point at which the stratosphere begins, the tropopause, is measured by where this temperature inversion starts taking place. The height of the stratosphere varies depending on what latitude we are talking about: at moderate latitudes, the stratosphere begins about 10 km (6 mi) above the surface and ends at 50 km (31 mi), at the poles, it starts at only 8 km (5 mi) altitude. This is because the ground at the poles is so cold, it doesn't take much to produce greater temperatures, and thus the stratosphere begins earlier.
It is one of the layers of the atmosphere.
There are five major layers of the Earth's atmosphere (the others are parts of the layer). From lowest to highest: 1.Troposphere [Tropopause] 2. Startosphere [ Ozone Layer, Stratopause] 3. Mesosphere [Mesopause] 4. Thermosphere [ Thermopause, Ionosphere] 5. Exosphere [Exobase]
The very thin layer between the earths crust and the stratosphere is commonly refered to as the troposphere.
There is a high concentration of ozone in startosphere because of the UV rays. These UV rays are the ones that help in the creation of ozone.
The ozone layer was formed in startosphere by the action of UV rays. these radiations just decomposed oxygen into oxygen atom which combines with oxygen to form ozone.
Think about all of the emissions/gases we pollute our earth with. These gases are called greenhouse gases. Greenhouse gases damage different types of layers of our atmopshere (which include troposphere, startosphere, ozone layer, mesophere, and themosphere).

Ozone does act like a policeman in the stratosphere as it guards its master i.e. EARTH against the EVILS which includes the harmful Ultraviolet radiations. These radiations are the ones which cause depletion in the ozone layer and thus decrease the amount of protection against the UV rays which we were initially gifted with.
There 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. It consists of O3 molecules that break apart under the impact of rays and then re-form to re-create the barrier again.
