The heterosphere extends from the turbopause to the edge of a planet's atmosphere and lies directly above the homosphere.

Where can you find heterosphere?

The heterosphere is the upper portion of the Earth's atmosphere, in which gases are fractionated according to their molecular weight. It lies above the homosphere, where chemical constituents are well mixed.

Where is the homosphere and heterosphere?

The homosphere is the lowest part of the Earth's atmosphere, lying between the Earth's surface and the heterosphere, the upper part. It is the atmosphere, occurring below around 100 km (60 miles).

Why is it called the heterosphere?

The upper 100 km and more is known as the heterosphere because its composition varies depending on the height. The atmospheric gases are separated based on their molecular mass where the lighter gases are concentrated in the upper layers.

Which layer has covered the largest area of heterosphere?

Mesosphere: The mesosphere forms the top-most layer of the homosphere. This layer exists above an altitude of roughly 50 kms and extends upto 80 kms. The temperature in the mesosphere decreases as the altitude increases.

What are the two layers of heterosphere?

The regions of the stratosphere and the mesosphere, along with the stratopause and mesopause are called the middle atmosphere. The mesosphere is the layer of the earth's atmosphere that is immediately above the stratosphere and below the thermosphere and is located from about 31 mi.

What are the four layers of heterosphere?

ATMOSPHERE
  • The atmosphere is a layer of gas surrounding the Earth which extends to a height of several hundred kilometers. ...
  • The homosphere can be subdivided into three strata, the troposphere , the stratosphere, and the mesosphere.

What is the highest level of Heterosphere?

The Earth's heterosphere begins at about 100 km altitude and extends to the outer reaches of its atmosphere. It incorporates most of the thermosphere and all of the exosphere.

What is the warmest layer of Earth's atmosphere?

The thermosphere is often considered the "hot layer" because it contains the warmest temperatures in the atmosphere. Temperature increases with height until the estimated top of the thermosphere at 500 km. Temperatures can reach as high as 2000 K or 1727 ºC in this layer (Wallace and Hobbs 24).


What is the coldest point in the atmosphere?

The top of the mesosphere, called the mesopause, is the coldest part of Earth's atmosphere. Temperatures in the upper mesosphere fall as low as −101 °C (172 K; −150 °F), varying according to latitude and season.

What are the 2 highest layers in the atmosphere?

From lowest to highest, the major layers are the troposphere, stratosphere, mesosphere, thermosphere and exosphere.

What is main function of atmosphere?

Atmosphere is essential for life on Earth as it supplies oxygen, water, CO2 and some nutrients (N) to living organisms, and protects living organisms from temperature extremes and excessive UV radiation.

Which is not a homosphere?

11. Which of the following mentioned layers is NOT a homosphere? Explanation: Homospheric layers of atmosphere include layers where chemical composition is independent of molecular weight of gases due to mixing by turbulence. Hence the lower layers such as troposphere, ionosphere and mesosphere are homospheres.


What is the most abundant gas in the atmosphere?

Gases. The most abundant naturally occurring gas is Nitrogen (N2), which makes up about 78% of air. Oxygen (O2) is the second most abundant gas at about 21%. The inert gas Argon (Ar) is the third most abundant gas at .

What is homosphere and heterosphere?

The homosphere is the layer of an atmosphere where the bulk gases are homogeneously mixed due to turbulent mixing or eddy diffusion. ... Above the homopause is the heterosphere, where diffusion is faster than mixing, and heavy gases decrease in density with altitude more rapidly than lighter gases.

How are the gases in the heterosphere arranged?

structure of the atmosphere

…in the zone called the heterosphere, various atmospheric gases are separated by molecular mass, with the lighter gases being concentrated in the highest layers. Above 1,000 km (about 600 miles), helium and hydrogen are the dominant species.

What are the 7 layers of earth?

If we subdivide the Earth based on rheology, we see the lithosphere, asthenosphere, mesosphere, outer core, and inner core. However, if we differentiate the layers based on chemical variations, we lump the layers into crust, mantle, outer core, and inner core.


Which is hotter thermosphere or exosphere?

The thermosphere is directly above the mesosphere and below the exosphere. ... The thermosphere is typically about 200° C (360° F) hotter in the daytime than at night, and roughly 500° C (900° F) hotter when the Sun is very active than at other times.

What are the 7 layers of atmosphere?

Layers of the atmosphere
  • The Troposphere. This is the lowest part of the atmosphere - the part we live in. ...
  • The Stratosphere. This extends upwards from the tropopause to about 50 km. ...
  • The Mesosphere. The region above the stratosphere is called the mesosphere. ...
  • The Thermosphere and Ionosphere. ...
  • The Exosphere. ...
  • The Magnetosphere.

What layer do jet planes fly?

Commercial jet aircraft fly in the lower stratosphere to avoid the turbulence which is common in the troposphere below. The stratosphere is very dry; air there contains little water vapor. Because of this, few clouds are found in this layer; almost all clouds occur in the lower, more humid troposphere.

Which atmospheric gas slows down the speed of oxygen?

Nitrogen gas slows down the speed of oxygen.


What is the 2 layer of the atmosphere?

Most of the important processes of the atmosphere take place in the lowest two layers: the troposphere and the stratosphere.

Which layer of the atmosphere is broken down into two sub layers?

The thermosphere is divided into two sub-layers. The lower layer, called the ionosphere (eye AHN uh sfeer), begins about 80 kilometers above the surface and extends to about 400 kilometers. Energy from the sun causes gas molecules in the ionosphere to become electrically charged particles called ions.

What is the average height of the troposphere?

The troposphere extends upward to about 10 km (6.2 miles or about 33,000 feet) above sea level. The height of the top of the troposphere varies with latitude (it is lowest over the poles and highest at the equator) and by season (it is lower in winter and higher in summer).
