What are the advantages of ozone layer?
The major function of the ozone layer is to stop the harmful radiations coming from the sun as well as from stars. Ozone captures those radiations which are of low wavelength. It also stops the harmful ultraviolet rays. These radiations are very harmful for living beings.
Which answer best describes the role of the ozone layer?
The ozone layer acts as a shield for life on Earth. Ozone is good at trapping a type of radiation called ultraviolet radiation, or UV light, which can penetrate organisms’ protective layers, like skin, damaging DNA molecules in plants and animals.
What is a fact about the exosphere?
The air in the exosphere is very thin, and is made up mostly of helium, and hydrogen. Traces of other gases such as atomic oxygen and carbon dioxide can also be found. The upper level of the exosphere is the farthest point from earth that is still affected by earth’s gravity.
Why is the exosphere unique?
The outermost layer “Exo” means outside and is the same prefix used to describe insects like grasshoppers that have a hard shell or “exoskeleton” on the outside of their body. The exosphere is the very edge of our atmosphere. This layer separates the rest of the atmosphere from outer space.
What is the main function of the exosphere?
Functions of the Exosphere Its functions to act as a transitional medium to a zone under the influence of gravity. It also helps the atoms to escape from the atmosphere to outer space. Unlike other atmospheric layers, it is the only layer of the atmosphere that has a definite shape.
Is the troposphere the thickest layer?
The layer closest to Earth’s surface is the troposphere, reaching from about seven and 15 kilometers (five to 10 miles) from the surface. The troposphere is thickest at the equator, and much thinner at the North and South Poles.
Why does the temperature increase with altitude in the exosphere?
Temperature in the stratosphere rises with increasing altitude, because the ozone layer absorbs the greater part of the solar ultraviolet radiation. The ozone layer is an absorbing agent that protects life on Earth.
What is relationship between temperature and height in the troposphere?
The troposphere gets its heat from the ground, and so temperature decreases with altitude. Warm air rises and cool air sinks and so the troposphere is unstable. In the stratosphere, temperature increases with altitude. The stratosphere contains the ozone layer, which protects the planet from the Sun’s harmful UV.
What are the relationship between temperature and height in the FF?
Answer Expert Verified Generally, the temperature decreases as the height increases.
