Question

Define the following terms

1.Troposphere
2.Stratosphere
3.Mesophere
4.Exosphere
5.Thermosphere​

Answer 1

Answer:

Explanation:

1. The troposphere is the lowest layer of Earth's atmosphere. Most of the mass (about 75-80%) of the atmosphere is in the troposphere. Most types of clouds are found in the troposphere.

2. The stratosphere is a layer of Earth's atmosphere. It is the second layer of the atmosphere as you go upward. Ozone, an unusual type of oxygen molecule that is relatively abundant in the stratosphere, heats this layer as it absorbs energy from incoming ultraviolet radiation from the Sun.

3. The measosphere is the third major layer of the Earth's atmosphere, directly above the stratosphere and directly below the thermosphere. In the mesosphere, temperature decreases as altitude increases.

4. The exosphere is the outermost layer of the Earth's atmosphere. It starts at an altitude of about 500 km and goes out to about 10,000 km.

5. the region of the atmosphere above the mesosphere and below the height at which the atmosphere ceases to have the properties of a continuous medium is called thermosphere.

Answer 2

Troposphere : It is the lowest layer of earth's atmosphere

2. Stratosphere: the layer of the earth’s atmosphere between about 10 and 50 kilometres above the surface of the earth

3. Mesophere:the region of the earth’s atmosphere between about 50 and 80 kilometres above the surface of the earth, above the stratosphere and below the thermosphere

4.Exosphere : the outermost region of a planet's atmosphere.

5. Thermosphere : the region of the atmosphere above the mesosphere
