Atmosphere Questions and Answers – Page 4

Correct Answer: Option B — Mesosphere. Mesosphere is correct because it is extends to the mesopause. Mesosphere is also associated with it contains some of the coldest atmospheric temperatures. A further identifying fact is that Mesosphere is it contains some of the coldest atmospheric temperatures. Another useful fact is that Mesosphere is associated with many meteors burn up in it. Why the other options are incorrect: Option A — Thermosphere: It is lies above the mesopause and is associated with temperature rises greatly as high-energy radiation is absorbed; those are the identifying facts of Thermosphere. Option C — Exosphere: It is gradually merges into outer space and is associated with particles are extremely sparse; those are the identifying facts of Exosphere. Option D — Ozone layer: It is located mainly in the stratosphere and is associated with absorbs much of the Sun's harmful ultraviolet radiation; those are the identifying facts of Ozone layer. Exam Takeaway: Link Mesosphere with “extends to the mesopause” and “it contains some of the coldest atmospheric temperatures” for quick revision.

Correct Answer: Option A — Mesosphere. Mesosphere is correct because it is the layer above the stratosphere. Mesosphere is also associated with extends to the mesopause. A further identifying fact is that Mesosphere is it contains some of the coldest atmospheric temperatures. Another useful fact is that Mesosphere is associated with many meteors burn up in it. Why the other options are incorrect: Option B — Thermosphere: It is a very thin upper atmospheric layer and is associated with lies above the mesopause; those are the identifying facts of Thermosphere. Option C — Exosphere: It is the outermost atmospheric region and is associated with gradually merges into outer space; those are the identifying facts of Exosphere. Option D — Ozone layer: It is a region of enhanced ozone concentration and is associated with located mainly in the stratosphere; those are the identifying facts of Ozone layer. Exam Takeaway: Link Mesosphere with “the layer above the stratosphere” and “extends to the mesopause” for quick revision.

Correct Answer: Option D — Stratosphere. Stratosphere is correct because it is it is relatively stable and has little vertical mixing. Stratosphere is also associated with the layer above the troposphere. A further identifying fact is that Stratosphere is temperature rises with height because ozone absorbs ultraviolet radiation. Another useful fact is that Stratosphere is associated with it is relatively stable and has little vertical mixing. Why the other options are incorrect: Option A — Mesosphere: It is many meteors burn up in it and is associated with the layer above the stratosphere; those are the identifying facts of Mesosphere. Option B — Thermosphere: It is auroras occur mainly in this region and is associated with a very thin upper atmospheric layer; those are the identifying facts of Thermosphere. Option C — Exosphere: It is light gases such as hydrogen and helium dominate and is associated with the outermost atmospheric region; those are the identifying facts of Exosphere. Exam Takeaway: Link Stratosphere with “it is relatively stable and has little vertical mixing” and “the layer above the troposphere” for quick revision.
