Which labeled placemark in the layers folder represents the stratosphere?
Leya [2.2K]
The atmosphere is divided into different regions, called layers. The layer closest to the surface is known as troposphere, after which comes the stratosphere. The stratosphere begins at an altitude of 10 miles above the surface of the earth and stretches up to 31 miles above the surface of the earth. It is the second layer of the atmosphere (beginning from the surface of the earth) and it is the region which contains ozone, which plays a vital role in stopping ultraviolet radiation from reaching the earth's surface.

Which statement correctly describes other ways in which nebulae and stars are different? A. A star always has a higher density t
wel

The answer is; A

Nebulae are clouds of dust and gas in space. When local areas in nebulae start to collapse under their own weight and fusion begins, a star is born. This, therefore, means that a star is denser than nebulae because it requires that atoms fuse for it to form. Fusion creates heavier atoms from light atoms.
