Question

explain layers of atmosphere with diagram​

Answer 1

$\huge \dag\: \LARGE {\rm {\underline{ \underline{\gray {Layers \: Of \: Atmosphere: }}}}}$

• Many layers of air are present in the atmosphere . Scientists have divided the atmosphere into four layers . These are :

$\leadsto \boxed{ \red {\sf\ \: 1. \: \:The \: Troposphere: }}$

• It gets its name from the Greek word tropos which means " a turn ". This is because the air there is constantly circulating .

• The troposphere is the layer of of the atmosphere nearest to the Earth's Surface . As well as a mixture of gases , this layer contains cloud's , dust and pollution .

• It extends to between 10 km ( 6 miles ) and 20 km ( 12 miles ) from the Earth .

• The Troposphere is the layer where the weather is produced .

$\leadsto \: \boxed {\sf{ \red {\:2. The \: Stratosphere: }}}$

• The upper limit of the Stratosphere is around 50 km ( 30 miles ) from Earth's surface .

• When you fly in a plane , you fly in this layer , just above the clouds .

• The stratosphere contains a concentration of ozone gas . This gases the Stratosphere to heat up .

• This layer of ozone gas is very important , as it helps to shield the Earth from harmful rays , which can cause skin cancer and damage to the eyes .

$\leadsto \: \boxed{ \sf {\red {3. \: The \:Mesosphere: }}}$

• The mesosphere reaches a height of around 80 km ( 50 miles )

• Temperatures here are the coolest in the atmosphere because the mesosphere contains no ozone , dust or clouds , which absorb energy from the sun .

• It is hottest at the bottom due to the warmer Stratosphere layer below.

$\leadsto \boxed {\sf { \red { \: 4. \: The \: Thermosphere: }}}$

• Temperature in the Thermosphere can be extemely high , reaching up to 1,500°C .

• This is because there is a high proportion of gas called atomic oxygen .

• This absorbs ultraviolet rays from the Sun in the same way that ozone does.
