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.

The earth's atmosphere is divided into layers based on the vertical profile of:

  1. Air pressure

  2. Air temperature

  3. Air density

  4. Wind speed
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

The atmosphere is stratified into layers like the troposphere, stratosphere, mesosphere, and thermosphere based on how the air temperature changes with altitude.

In which layer of atmosphere rainbow formation occurs?

  1. Mesosphere

  2. Stratosphere

  3. Ionosphere

  4. Troposphere

D Correct answer
Explanation

Rainbows are optical phenomena caused by the refraction and reflection of light in water droplets, which are found in the troposphere where weather occurs.

Which of the following layer of atmosphere receives an extraordinary amount of energy from the sun?

  1. Stratosphere

  2. Ionosphere

  3. Mesosphere

  4. None of the above
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

The ionosphere contains high concentrations of ions and free electrons and is directly exposed to high-energy solar radiation, which causes ionization.

PAN is

  1. poisonous american nuisance

  2. primary air pollutant

  3. photochemical oxidant

  4. particulate atmospheric nitrogen compound
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

PAN (Peroxyacytyl nitrate) is a toxic chemical that is an important component of smog.PAN molecules are generally composed of carbon, hydrogen, oxygen, and nitrogen atoms.

So the correct answer will be 'PARTICULATE ATMOSPHERIC NITROGEN COMPOUND'.
