Question

structure of the atmosphere
​

Answer 1

Answer:

Structure of atmosphere is troposphere that we live in near surface of earth,the stratosphere that house the ozone later,the mesosphere a colder and lower density layer with about 0.1 percent of atmosphere and thermosphere top layer where air is hot but very thin

Answer 2

$\large\underline\mathfrak\purple{Structure\:Of\:Atmosphere}$

　　　　　　　　　　　 

( The atmosphere is divided into 5 layers )

• TROPOSPHERE

• STRATOSPHERE

• MESOSPHERE

• THERMOSPHERE

• EXOSPHERE

　　　　　　　　　　　 

$\large{\underline{\boxed{\mathrm\blue{✟Troposphere}}}}$

• ✦ The Troposphere is the lowest layer of the Earth.

• ✦ It makes up approximately 75% of the total mass of the atmosphere and contains 99% of the atmosphere's water.

• ✦ It extends upto 18 km at the Equator, 8km at the poles.

• ✦ The air we breathe exist here and all weather phenomena.

　　　　　　　　　　　 

$\large{\underline{\boxed{\mathrm\pink{✟Stratosphere}}}}$

• ✦ The Stratosphere is the second layer of the Atmosphere.

• ✦ It extends to a height of 50 km above the Earth's surface.

• ✦ It contains ozone which absorbs the ultraviolet radiation of the sun.

　　　　　　　　　　　 

$\large{\underline{\boxed{\mathrm\green{✟Mesosphere}}}}$

• ✦ The Mesosphere lies above the stratosphere.

• ✦ It is the coldest layer of the atmosphere because of the low concentrations of ozone.

　　　　　　　　　　　 

$\large{\underline{\boxed{\mathrm\red{✟Thermosphere}}}}$

• ✦ Temperatures rise in the Thermosphere as gas molecules absorb X - ray radiation resulting in the breaking of the gas molecules.

• ✦ Satellites move around our planet in the thermosphere.

　　　　　　　　　　　 

$\large{\underline{\boxed{\mathrm\orange{✟Exosphere}}}}$

• ✦ The Exosphere is the uppermost layer of the Atmosphere.

• ✦ It is very thin with only traces of hydrogen and helium present in it.
