Question 55:

as the altitude increases, the temperature of the atmosphere decreases in this layer of the atmosphere.

i. troposphere

ii. stratosphere

iii. mesosphere

iv. thermosphere

question 55 options:

i and iii

ii and iii

i and ii

ii and iv

Option (1)

Explanation:

The atmosphere plays an important role in controlling the earth's climate. This atmosphere is comprised of different layers. They are as follows-

(a) Troposphere- This layer extends up to a height of about 10 km from the ground surface. In this layer, the temperature and altitude are inversely proportional to one another. This decrease in the temperature with increasing height is known as the Lapse rate and is 6.5 degree C/km.

(b) Stratosphere- This layer is present above the troposphere. It extends from about 10 to 50 km above the surface. Here, the temperature increases with height. It is because of the presence of ozone in this layer that warms the layer.

(c) Mesosphere- This layer is above the stratosphere and below the thermosphere. It extends vertically from about 50 to 80 km above the ground surface. The temperature again decreases with height in this layer.

(d) Thermosphere- This layer forms the outermost layer. Here, the temperature and height are directly proportional to each other.

Thus, the temperature decreases with altitude in the layers, namely the troposphere and the mesosphere.

Hence, the correct answer is option (1).

a characteristic is a deep cut in the earth or left over rock aka till.
