Question

Assertion (A): The Atmosphere is divided into five layers.

Reason (R): The Atmosphere is divided into layers on the basis of temperature conditions.

Options

• Both A and R are true, and R is the correct reason for A.

• Both A and R are true, but R is not the correct reason for A.

• A is true, and R is false.

• A is false, and R is true.

Answer 1

Both A and R are true, and R is the correct reason for A.

Explanation:

The atmosphere is divided into five layers based on temperature variations with altitude. Each layer has a distinct temperature pattern, like the Troposphere, where temperature decreases with height, the Stratosphere, where it increases, and so on. These temperature differences create clear boundaries that define each atmospheric layer. Thus, the division into five layers is primarily determined by how temperature changes in different parts of the atmosphere.
