Which layer of the Earth's atmosphere contains the ozone layer?
Troposphere
Stratosphere
Mesosphere
Thermosphere
Stratosphere
The stratosphere is the second major layer of Earth's atmosphere, located directly above the troposphere and below the mesosphere. It contains the ozone layer, which plays a crucial role in absorbing most of the Sun's harmful ultraviolet radiation.
The stratosphere is the second major layer of Earth's atmosphere, located directly above the troposphere and below the mesosphere. It contains the ozone layer, which plays a crucial role in absorbing most of the Sun's harmful ultraviolet radiation.
The atmosphere is vertically stratified into five main layers based on temperature gradients: troposphere, stratosphere, mesosphere, thermosphere, and exosphere, with the stratosphere spanning approximately 12 to 50 kilometers above the surface.
The stratosphere extends from about 12 km to 50 km above the Earth's surface.
The ozone layer is predominantly concentrated in the lower stratosphere between 15 and 35 km altitude.
Unlike the troposphere, temperature in the stratosphere increases with altitude due to ozone ultraviolet absorption.
Option A (Troposphere) is the lowest layer where weather phenomena occur and contains about 75 percent of the atmosphere's mass.
Option C (Mesosphere) lies above the stratosphere and is the coldest layer of the atmosphere where meteors disintegrate.
Option D (Thermosphere) features very high temperatures and contains the ionosphere, which reflects radio waves.
B is correct тАФ The stratosphere houses the ozone layer, which protects life on Earth by filtering out harmful ultraviolet rays.
Geography questions in Indian competitive exams regularly test the height, temperature trends, and specific phenomena associated with each of the atmospheric layers.
