The Corona. The outermost layer of the Sun is called the corona or the crown. The corona is very thin and faint and is therefore very difficult to observe from the earth.Typically, we observe the corona during a total solar eclipse or by using a coronagraph telescope which simulates an eclipse by covering the bright solar disk.he Corona. The outermost layer of the Sun is called the corona or the crown. The corona is very thin and faint and is therefore very difficult to observe from the earth.
Most ozone (about 90%) resides in a layer that begins between 6 and 10 miles (10 and 17 kilometers) above the Earth's surface and extends up to about 30 miles (50 kilometers). This region of the atmosphere is called the stratosphere.The ozone in this region is commonly known as the ozone layer. The remaining ozone is in the lower region of the atmosphere, which is commonly called the troposphere. The figure (above) shows an example of how ozone is distributed in the atmosphere.zone thus plays a key role in the temperature structure of the Earth's atmosphere. Without the filtering action of the ozone layer, more of the Sun's UV-B radiation would penetrate the atmosphere and would reach the Earth's surface.
