Typically, water vapor occupies about what percentage of the air's volume near the earth's surface?

  1. About 78 percent

  2. About 21 percent

  3. Close to 10 percent

  4. Less than 4 percent
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Water vapor is a variable gas in the atmosphere, typically ranging from 0 to 4 percent by volume depending on temperature and location. It is most concentrated near the surface in tropical regions.

At which latitude heat gain through insolation approximately equals heat loss through terrestrial radiation:

  1. $22.5^0$ North and South
  2. $40^0$ North and South
  3. $42.5^0$ North and South
  4. $66^0$ North and South

B Correct answer
Explanation

Heat gain from solar insolation approximately balances heat loss from terrestrial radiation around the 40 degree latitude lines in both the Northern and Southern Hemispheres. Lower latitudes receive a net surplus of energy, while higher latitudes experience a net deficit.

If climate change keeps on disrupting atmospheric pressure, it would bring ice age in

  1. America

  2. Northern Europe

  3. Africa

  4. Canada

B Correct answer
Explanation

Disruption of the North Atlantic Current, often linked to climate change, could lead to a significant cooling effect in Northern Europe. This is a common hypothesis regarding the impact of melting Arctic ice on ocean circulation.

The $CO _{2}$ content by volume, in the atmospheric air is about

  1. 3.34%

  2. 4%

  3. 0.0314%

  4. 2.1%.
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

The carbon dioxide present in the atmosphere is generally the result of respiration by animals during the day and the emissions by various vehicles, industries and machines. All these activities account for a total of approximately 0.04% CO2 in the atmospheric air.

So, the correct answer is '0.0314%'.

Ozone is formed in stratosphere by action of ultravoilet radiations on oxygen.

  1. True

  2. False

  3. Either

  4. Neither
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation
Ozone (O3) molecule is made up of three oxygen atoms. It is formed in the stratosphere when single oxygen atom combines with a molecule of oxygen i.e. when [O] combines with O2. Oxygen molecule consisting of two oxygen atoms splits into atomic oxygen in the presence of ultraviolet radiation. The atomic oxygen then combines with another molecule of oxygen to form ozone.
The reactions are as follows:
      UV light
O2 ---------------> [O] + [O]
[O] + O2 ---------->O3
Hence, the statement given in the question is correct.
So, the correct answer is 'True'.

Closest atmospheric layer to earth's surface is known as

  1. Boundary Layer

  2. Atmosphere

  3. Biosphere

  4. Hydrosphere
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

The troposphere is the lowest layer, but the boundary layer is the specific portion of the troposphere that is directly influenced by the Earth's surface. While 'troposphere' is the standard answer for atmospheric layers, 'Boundary Layer' is technically correct in meteorological contexts.
