Which among the following is not a layer of the atmosphere?a)Exosphere...
Answer:
The correct answer is B: Lithosphere. The lithosphere is not a layer of the atmosphere.
Explanation:
The atmosphere is divided into several layers based on temperature changes and composition. The layers of the atmosphere, in order from closest to the Earth to farthest away, are:
1. Troposphere: This is the lowest layer of the atmosphere, where weather occurs and where most of the Earth's air mass is found.
2. Stratosphere: Above the troposphere, the stratosphere contains the ozone layer, which absorbs and protects against harmful ultraviolet radiation from the Sun.
3. Mesosphere: The mesosphere is the third layer of the atmosphere and is characterized by decreasing temperatures with altitude.
4. Thermosphere: The thermosphere is the second highest layer of the atmosphere and is where the northern and southern lights occur. It is also the layer where satellites orbit the Earth.
5. Exosphere: The outermost layer of the atmosphere, the exosphere gradually fades into space. It is composed mainly of extremely low-density hydrogen and helium atoms.
Lithosphere, on the other hand, refers to the rigid outer part of the Earth, including the crust and upper mantle. It is not a part of the atmosphere.
Therefore, the correct answer is B: Lithosphere.
Which among the following is not a layer of the atmosphere?a)Exosphere...
Explanation:
Lithosphere:
- The lithosphere is the rigid outer layer of the Earth, consisting of the crust and the solid outermost part of the upper mantle.
- It is not a layer of the atmosphere but rather a part of the Earth's structure.
Layers of the Atmosphere:
- The Earth's atmosphere is divided into five main layers based on temperature and composition.
- These layers, from the Earth's surface outward, are the troposphere, stratosphere, mesosphere, thermosphere, and exosphere.
- Each layer has unique characteristics and plays a specific role in the Earth's atmospheric system.
Exosphere, Mesosphere, Troposphere:
- The exosphere is the outermost layer of the Earth's atmosphere, extending from about 500 kilometers above the Earth's surface.
- The mesosphere is the third layer of the Earth's atmosphere, located above the stratosphere and below the thermosphere.
- The troposphere is the lowest layer of the Earth's atmosphere, where almost all weather events occur.
Conclusion:
- The lithosphere is not a layer of the atmosphere but rather a part of the Earth's structure, consisting of the crust and the solid outermost part of the upper mantle.
- The layers of the atmosphere play important roles in regulating the Earth's climate and weather patterns.
