Question

Which of the following layers of the atmosphere consists of artificial satellites?
A. Exosphere
B. Thermosphere
C. Troposphere
D. Stratosphere

Answer 1

Hint:The Earth's atmosphere is divided into layers, each with its own set of characteristics. These layers, which ascend from ground level, are known as the troposphere, stratosphere, mesosphere, thermosphere, and exosphere. The exosphere progressively disappears into interplanetary space.

Complete answer:
To choose the proper alternative, we will first write about all of the distinct layers, and then we will decide which one is correct based on the supplied question.

Exosphere:Closer to the exobase, the exosphere layer is primarily composed of extremely low densities of hydrogen, helium, and various heavier molecules such as nitrogen, oxygen, and carbon dioxide. The exosphere is home to the majority of Earth's satellites.

Thermosphere:The major components of air in the upper thermosphere are atomic oxygen, atomic nitrogen, and helium . The thermosphere absorbs a large portion of the Sun's X-ray and UV energy.

Troposphere:The troposphere contains the majority of the atmosphere's mass (about 75 - 80 % ). The troposphere is home to the majority of clouds, and it is also where the majority of weather occurs. Air pressure and density both drop when one ascends in altitude.

Stratosphere:The ozone layer, which is extremely vital, is found in the stratosphere. The ozone layer shields us from the sun's ultraviolet radiation (UV). In fact, the ozone layer absorbs the majority of the UV energy emitted by the sun. Without this layer of defence, life as we know it would be impossible.
Hence, from the above gathered information it can be concluded that the Exosphere is the layers of the atmosphere consisting of artificial satellites.

So, the correct option is A.

Note: It should be emphasised that air pressure exists anywhere there is an atmosphere. The weight of air exerts pressure on the earth's surface, which is referred to as atmospheric pressure. A barometer is used to measure atmospheric pressure. The higher the pressure, the denser the air molecules. Altitude, moisture, and temperature all have an effect on air pressure.
