Question

36. Arrange the layers of the atmosphere as per the following terms related in a sequence, respectively. Inversion layer, convection currents, auroras, absorbs harmful ionizing radiations and burning up of meteorites

(1) troposphere

(2) stratosphere

(3) exosphere

(4) mesosphere

(5) ionosphere

• A. 45312
• B. 12354
• C. 21534
• D. 12435

Answer 1

The correct option is C

21534

Explanation:

Inversion layer:

• The layer above the troposphere is called the stratosphere and it extends up to 50 km above the earth's surface.
• Above 25 km, temperature increases due to ultraviolet (UV) radiation absorption.
• This region of increase in temperature is called the inversion layer.

Convection currents:

• The layer of the atmosphere which extends up to 20 km above the earth's surface is called the troposphere.
• Convection currents are present in this layer.

Auroras:

• The layer of the atmosphere which extends up to 690-950 km above the earth's surface is called the thermosphere or ionosphere.
• Auroras appear in this layer. Auroras are the luminous streams that are visible from the earth's surface at northern and southern latitudes.

Harmful ionizing radiations:

• The layer of the atmosphere which extends up to 10,000 km above the earth's surface is called the exosphere.
• This layer absorbs harmful ionizing radiation.

Burning up of meteorites:

• The layer of the atmosphere which extends up to 85 km above the earth's surface is called the mesosphere.
• Meteorites burn up in this layer.

Hence, option (C) is the correct answer. The correct sequence is 21534.
