Which of the following gas is present in large quantity in atmosphere?
-
Oxygen
-
Hydrogen
-
Nitrogen
-
Methane
Atmosphere is the layer of gases surrounding the planet. The major gases present in atmosphere are nitrogen, oxygen, argon, carbon dioxide and other gases in minute quantity. Among all the gases present in atmosphere, nitrogen constitutes highest amount. Percentage of nitrogen present in atmosphere is 78.
Which of the following gases protects us from harmful sun rays?
-
Carbondioxide
-
Nitrogen
-
Ozone
-
Sulphurdioxide
Ozone is an inorganic molecule which is formed by three atoms of oxygen. It is an allotrope of oxygen. Ozone protects us from harmful sun rays. It is present in ozonosphere region of stratosphere. Ozone layer absorbs dangerous UV radiation from sun rays. It protects us from skin cancer and other health damage. However, ozone layer is depleting due to harmful gases like CFCs, i.e. Chlorofluorocarbons.
Ozone is present in which of the layers of atmosphere ____________.
-
Troposphere
-
Stratosphere
-
Mesosphere
-
Ionosphere
Ozone is present in the Stratosphere. This region is known as ozonosphere. This region contains high concentrations of ozone in comparison to other parts of the atmosphere. It absorbs UV light radiations coming from sun and protect the earth. Ozone is mainly found in the lower portion of the stratosphere.
Anything that brings a change to the natural composition of air is known as _____________.
-
disaster
-
cyclone
-
pollutant
-
hazard
What is the reason for the Troposphere to be at a greater height at the Equator?
-
Conventional currents
-
Conduction
-
Terrestrial radiation
-
All of above
Layer where the atmosphere thins out and merges with interplanetary space is called ______________.
-
Mesosphere
-
Ionosphere
-
Troposphere
-
Exosphere
Layer where the atmosphere thins out and merges with interplanetary space is called exosphere. Exosphere is the outermost layer of the Earth's atmosphere. It extends from about 600 km until it thins out to merge with interplanetary space. Due to this, exosphere is about 10,000 km or 6,200 miles thick or about as wide as the Earth. The top boundary of Earth's exosphere extends about halfway to the Moon.
In which layer of the atmosphere all the weather and climate phenomenon take place?
-
Mesosphere
-
Thermosphere
-
Troposphere
-
Stratosphere
Troposphere,
The altitudes/height of heavenly bodies appears to be greater than they actually are. This is due to ____________________.
-
Vertical motion of these heavenly bodies
-
Motions of the earth
-
Atmospheric refraction
-
These are visible because of light of the sun reflected from their surface

-
India
-
France
-
Japan
-
Malaysia
Which part of the atmosphere is called homosphere?
-
Atmosphere up to 70 km from the surface of the earth
-
Atmosphere up to 80 km from the surface of the earth
-
Atmosphere up to 90 km from the surface of the earth
-
Atmosphere up to 110 km from the surface of the earth
