Question

Greenhouse gas, $C{O}_2$ is confined to which layer of atmosphere?

• A. Only Troposphere
• B. Only Stratosphere
• C. Only Thermosphere
• D. Both Troposphere and Stratosphere

Answer 1

The correct option is A Only Troposphere

$C{O}_2$ is confined only to troposphere layer of atmosphere. This layer is located at 10 km above the sea level.
$C{O}_2$ forms about 0.03 percent by volume of the atmosphere.
Ozone layer is majorly found in stratosphere.
Atomic oxygen, nitrogen and helium are the main components of thermosphere.
