What is the primary function of atmosphere?

Answer: The primary function of the earth’s atmosphere is that it protects the earth from the harmful rays and acts a covering made of tiny particles. A small blanket of gases and particles combinely called as air. The air and water present on earth makes it a unique planet.

What are the main characteristics of the atmosphere?

In addition to containing nitrogen and oxygen, the atmosphere contains small particles, such as dust, volcanic ash, sea salt, dirt, and smoke. The next time you turn off the lights at night, shine a flashlight, and you will see some of these tiny particles floating in the air. Water is also found in the atmosphere.

What is the important of the atmosphere?

The atmosphere protects living things from the Sun’s most harmful rays. Gases reflect or absorb the strongest rays of sunlight (figure below). The atmosphere shields Earth from the most harmful solar rays.

What are examples of atmosphere?

Atmosphere is defined as the area of air and gas enveloping objects in space, like stars and planets, or the air around any location. An example of atmosphere is the ozone and other layers which make up the Earth’s sky as we see it. An example of atmosphere is the air and gases contained inside a greenhouse.

What is a simple definition of atmosphere?

1 : the whole mass of air that surrounds the earth. 2 : the gas surrounding a heavenly body (as a planet) The atmosphere of Mars is made up mostly of carbon dioxide. 3 : the air in a particular place. 4 : a surrounding influence or set of conditions an atmosphere of excitement.

What is the literal meaning of atmosphere?

An atmosphere (from the greek words ἀτμός (atmos), meaning ‘vapour’, and σφαῖρα (sphaira), meaning ‘ball’ or ‘sphere’) is a layer or a set of layers of gases surrounding a planet or other material body, that is held in place by the gravity of that body.

What is the concept of atmosphere?

Atmosphere refers to the gases surrounding a star or planetary body held in place by gravity. The composition of the Earth’s atmosphere is about 78 percent nitrogen, 21 percent oxygen, 0.9 percent argon, with water vapor, carbon dioxide, and other gases. The atmospheres of other planets have a different composition.

What is the importance of atmosphere Class 7?

The atmosphere blocks harmful ultra-violet radiations to reach Earth. The atmosphere contains oxygen, the gas living beings need to breathe to stay alive. The moisture it contains is an essential part of the water cycle. Green plants need the carbon dioxide present in the atmosphere for making food.

What is the importance of atmosphere Class 6?

The atmosphere protects the Earth from the solar radiation. It filters the harmful ultraviolet rays of the Sun. The atmosphere traps the required heat of the Sun and allows the rest to escape into space, thus maintaining a moderate temperature on the Earth. This ensures the existence of various life forms.

What is atmosphere very short answer?

Atmosphere is the thin layer of air that surrounds the earth. It is made up of various gases such as oxygen, nitrogen, carbon dioxides, dust particles and water vapour. The gravitational force of the earth holds the atmosphere around it.

What is structure of atmosphere?

The atmosphere consists of 4 layers: the troposphere, stratosphere, mesosphere, and thermosphere. The boundary between the stratosphere and the troposphere is called the tropopause. The jet stream sits at this level and it marks the highest point that weather can occur.

What is atmosphere Class 9?

An atmosphere is a blanket of gases that surrounds Earth. It is held near the surface of the planet by Earth’s gravitational attraction. Argon, oxygen and nitrogen from the three main constitutions of the atmosphere.

What is Earth’s atmosphere composition?

Composition of air Nitrogen — 78 percent. Oxygen — 21 percent. Argon — 0.93 percent. Carbon dioxide — 0.04 percent.

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 are the 7 layers of the Earth’s atmosphere?

The 7 Layers in Order

  • Exosphere.
  • Ionosphere.
  • Thermosphere.
  • Mesosphere.
  • Ozone Layer.
  • Stratosphere.
  • Troposphere.
  • Earth’s Surface.

Which gas is very rare in the Earth’s atmosphere?

Except for helium, which is mostly extracted from natural gas, oxygen, nitrogen and the other rare gases are extracted from the air that makes up Earth’s atmosphere….Annual production.

Rare gas Abundance in the atmosphere/ppm World production/tonnes per year
argon 9300 700 000
krypton 1.1 8
xenon 0.08 0.6

What is the rarest gas?


What is the rarest gas in the universe?

It’s not just Superman’s home planet; Krypton is one of the rarest gases on Earth, composing only 1 part per million of the atmosphere by volume. This noble gas is colorless and odorless. It has a full outer shell of electrons, rendering it largely inert to reactions with other elements.

Which gas is highly flammable?

A gas is considered flammable if it has the potential to explode or ignite when mixed with oxygen. In other words, if a certain level of flammable gas were to leak into the air, it could result in a fire. The most popular flammable gases are ammonia, butane, carbon monoxide, hydrogen, methane, and propane.

Can you burn air?

Air will never spontaneously combust, nor can it be made to burn non-spontaneously. Air is mostly nitrogen, which is not flammable. Nitrogen is also non-reactive in general, so it doesn’t support the combustion of other materials, either. After nitrogen, the most abundant gas in our air is oxygen.

What gases can explode?

In household accidents, the principal explosive gases are those used for heating or cooking purposes such as natural gas, methane, propane, butane.

Which is highly flammable kerosene or gasoline?

Kerosene is less volatile than gasoline. Its flash point (the temperature at which it will generate a flammable vapour near its surface) is 38 °C (100 °F) or higher, whereas that of gasoline is as low as −40 °C (−40 °F). This property makes kerosene a relatively safe fuel to store and handle.

Can the Sun ignite gasoline?

If, for example, you were to pour petrol into a metal tray and then leave it in the sun for a bit before throwing in a lit cigarette, that would probably ignite immediately, because the hot sunlight would have provided sufficient heat to create vapours dense enough to ignite.

What happens if u drink kerosene?

Like most chemicals, the amount of kerosene you are exposed to must be above a certain level to cause adverse health effects. Breathing large quantities of kerosene vapour or drinking kerosene-based liquids may cause non-specific signs such as dizziness, headache and vomiting.

What happens when you mix kerosene and gasoline?

no noticeable effect, at least not short term. Add more, and the engine will start running rough, and at some point, maybe fifteen to twenty percent kerosene, it will quit running at all. Repairs might be needed beyond getting the bad fuel out and putting in clean fuel. DON’T mix kerosene with gasoline.

Will kerosene damage a gas engine?

Kerosene is a volatile, like gasoline is, and not an oil like diesel is. It will burn okay. Kerosene is used as a burning fuel in furnances so it will not ruin the engine. Just fill up the tank with a higher octane fuel than usual or add a pint of octane booster.

Can a petrol car run on kerosene?

Practically speaking, you cannot start a petrol engine with kerosene but once started it can run on kerosene. Kerosene engines can use spark plug combustion unlike diesel. There may or may not be major issues with the engine you are using kerosene in depending on how sophisticted the engine is.
