Answer:
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.
The correct answers are:
- gas;
- petroleum;
These three North African countries do not have a big variety of natural resources, instead they only have very few, but it is the most valuable ones on the global market, the petroleum and the natural gas.
All three are very rich in these two resources, especially Libya, and they had a crucial role into the development and economic progress of these countries, by bringing them enormous trade revenue.
Answer:
It's Rio de la Plata :)))
Answer: In the upper atmosphere, the air is less dense, molecules are less and scattering, so the pressure also is less. It is known that the pressure decreases with height and the force of gravity also is less at higher altitudes than at the sea level. Near the surface of the earth, the air molecules are closely attached with one another, thereby increasing its density.
So the air is comparatively thin at the higher elevation, thereby maintaining a balance between the upper and the lower atmosphere.
The lithosphere is the hard, rocky, outer layer of the earth. Lithosphere means "rock sphere."
