Question

The composition of the atmosphere makes it a dynamic entity, however there are four thermal layers. Which of the following is in the correct order from the surface of the earth?

Options

• Thermosphere - Mesosphere - Stratosphere - Troposphere

• Troposphere - Mesosphere - Stratosphere - Thermosphere

• Troposphere - Stratosphere - Mesosphere - Thermosphere

• Thermosphere - Stratosphere - Mesosphere - Troposphere

Answer 1

Troposphere - Stratosphere - Mesosphere - Thermosphere

Explanation:

These are the four main thermal layers of the atmosphere arranged from the Earth's surface upward:

1. Troposphere – where weather occurs and temperature decreases with height.

2. Stratosphere – contains the ozone layer; temperature increases with height.

3. Mesosphere – temperature decreases with height; meteors burn here.

4. Thermosphere – temperature increases significantly; auroras occur here.
