What Is The Meaning Of Mesosphere

What is the meaning of word mesosphere?

What is the best definition of mesosphere?

mesosphere. / (ˈmɛsəʊˌsfɪə) / noun. the atmospheric layer lying between the stratosphere and the thermosphere characterized by a rapid decrease in temperature with height. the solid part of the earth’s mantle lying between the asthenosphere and the core.

What is mesosphere with example?

The mesosphere is also the layer where most meteors burn up upon atmospheric entrance. The downwelling over the nightside causes adiabatic heating of the air which forms a warm layer in the nightside mesosphere at the altitudes 90120 km. … Above 10km mi is the stratosphere followed by the mesosphere.

What’s in the mesosphere?

The mesosphere’s atmosphere is low density and made up of oxygen carbon dioxide and nitrogen. Although most of the meteors that reach the mesosphere are burned up some of their material hangs around afterwards including iron and other metallic atoms.

How do you speak mesosphere?

Here are 4 tips that should help you perfect your pronunciation of ‘mesosphere’:
  1. Break ‘mesosphere’ down into sounds: [MES] + [OHS] + [FEER] – say it out loud and exaggerate the sounds until you can consistently produce them.
  2. Record yourself saying ‘mesosphere’ in full sentences then watch yourself and listen.

What is thermosphere science?

thermosphere region of increasing temperature in Earth’s atmosphere that is located above the mesosphere. The base of the thermosphere (the mesopause) is at an altitude of about 80 km (50 miles) whereas its top (the thermopause) is at about 450 km.

What does thermo mean in thermosphere?


The thermosphere lies between the exosphere and the mesosphere. “Thermo” means heat and the temperature in this layer can reach up to 4 500 degrees Fahrenheit. … The thermosphere is home to the International Space Station as it orbits Earth.

What color is the mesosphere?

Can planes fly in mesosphere?

Mesosphere is a layer of earth’s atmosphere. It extends from about 50 to 85 km above our planet. It begins at the top of the stratosphere and ends at the mesosphere which is the coldest part of Earth’s atmosphere with temperatures below −143∘C . … We conclude that planes cannot fly in the mesosphere.

What does O Zone mean?


Ozone (O3) is a highly reactive gas composed of three oxygen atoms. It is both a natural and a man-made product that occurs in the Earth’s upper atmosphere. (the stratosphere) and lower atmosphere (the troposphere). Depending on where it is in the atmosphere ozone affects life on Earth in either good or bad ways.

How does mesosphere protect the Earth?

The mesosphere is the highest of the atmospheric layers in which gases are all mixed up instead of being layered in terms of their mass. 18. The mesosphere protects the Earth from meteors and asteroids by burning them up before they can reach its surface.

What is meant by trace gases?

From Wikipedia the free encyclopedia. Trace gases are those gases in the atmosphere other than nitrogen (78.1%) oxygen (20.9%) and argon (0.934%) which in combination make up 99.934% of the gases in the atmosphere (not including water vapor).

What are 3 facts about the thermosphere?

The main components of air in the thermosphere include helium atomic nitrogen and atomic oxygen. The thermosphere absorbs a lot of the UV radiation and X-ray given off by the sun. When the sun is more active and the thermosphere heats up more this layer of earth’s atmosphere increases in size.

What is the height of exosphere?

The exosphere is the outermost layer of the Earth’s atmosphere. It starts at an altitude of about 500 km and goes out to about 10 000 km. Within this region particles of atmosphere can travel for hundreds of kilometers in a ballistic trajectory before bumping into any other particles of the atmosphere.

Is Earth liquid inside?

The Earth’s interior is composed of four layers three solid and one liquid—not magma but molten metal nearly as hot as the surface of the sun. The deepest layer is a solid iron ball about 1 500 miles (2 400 kilometers) in diameter. Although this inner core is white hot the pressure is so high the iron cannot melt.

What is exosphere science?

The exosphere is the outermost layer of Earth’s atmosphere (i.e. the upper limit of the atmosphere) and extends from the exobase which is located at the top of the thermosphere.

How far above Earth is the range of mesosphere?

Mesosphere. This layer extends from around 31 miles (50 km) above the Earth’s surface to 53 miles (85 km).

What is the mesosphere layer of the Earth made of?

The mesosphere is beneath the asthenosphere. It encompasses the lower mantle where material still flows but at a much slower rate than the asthenosphere. A layer of liquid iron and nickel (and other elements) beneath the mesosphere.

What is ozone layer?

The ozone layer is the common term for the high concentration of ozone that is found in the stratosphere around 15–30km above the earth’s surface. It covers the entire planet and protects life on earth by absorbing harmful ultraviolet-B (UV-B) radiation from the sun.

What does exo mean in exosphere?

The exosphere is the outermost layer of our atmosphere. “Exo” means outside and is the same prefix used to describe insects like grasshoppers that have a hard shell or “exoskeleton” on the outside of their body.

Is the ISS in the thermosphere?

The space shuttle and the International Space Station both orbit Earth within the thermosphere! Below the thermosphere gases made of different types of atoms and molecules are thoroughly mixed together by turbulence in the atmosphere.

Can planes fly in the thermosphere?

The thermosphere is one of the layers in the atmosphere. Too thin for planes to fly and too cold for humans to survive. … However they are not the only things that happen in the thermosphere. The International Space Station also orbits the Earth in this layer.

Does the earth have a core?

The core found at the center of the Earth is made up of two parts. The outer layer comprised of liquid iron alloy is about 1 355 miles thick. The outer core is also thought to be responsible for Earth’s magnetic field. In contrast the inner core is made up of solid iron alloy with a radius of 760 miles.

What are the three layers of the earth?

Earth’s interior is generally divided into three major layers: the crust the mantle and the core. The hard brittle crust extends from Earth’s surface to the so-called Mohorovicic discontinuity nicknamed the Moho.

What color is Earth’s lithosphere?


There are several layers shown color coded brown and black green and reddish. The outermost brown and black layer above the Moho (boundary between crust and mantle) is the crust.

What is the Earth’s stratosphere?

Stratosphere. Located between approximately 12 and 50 kilometers (7.5 and 31 miles) above Earth’s surface the stratosphere is perhaps best known as home to Earth’s ozone layer which protects us from the Sun’s harmful ultraviolet radiation.

Why is 75 of the atmosphere’s mass found in the troposphere?

The troposphere contains approximately 80% of the mass of the atmosphere of the Earth. The troposphere is denser than all its overlying atmospheric layers because a larger atmospheric weight sits on top of the troposphere and causes it to be most severely compressed.
