Atmospheric Structure and Ozone

1,401 Questions

Atmospheric structure and ozone layer topics examine the Earth's atmospheric layers, the impact of solar radiation, and ozone depletion mechanisms. These environmental science concepts are crucial for general awareness sections in multiple competitive examinations. Review these questions to solidify your understanding of the stratosphere, polar vortex effects, and greenhouse gases.

Atmospheric Structure and Ozone Questions

Multiple choice geography environmental changes atmosphere as a green house global warming and climate change energy from the sun

Carbon dioxide and some other gases trap the heat radiated by the earth and cause ________.

  1. Global warming

  2. Ozone depletion

  3. Greenhouse effect

  4. Acid rain
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

The greenhouse effect occurs when gases like carbon dioxide trap heat in the atmosphere, preventing it from escaping into space, which leads to warming.

The ozone layer absorbs __________ and protects the living beings of the earth. 

  1. water vapour

  2. light

  3. infrared rays

  4. ultraviolet rays
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

The ozone layer basically absorbs harmful emissions from the sun like the ultraviolet rays, which is why life on earth is able to thrive. No other planet known to man has conditions that can favor life, and without the ozone layer, Earth would also become unable to support life. Below are some things that would happen if the ozone layer was damaged to any extent.

Cancer: one of the things that would be frequently experienced by human beings on Earth is skin cancer. Since the layer would not be able to effectively block UV rays, human skin would most likely be endangered.

Cataracts: this refers to a condition where human vision goes blurred. Almost all human beings on earth would have some sort of visual impairment without the ozone layer.

Which gas is responsible for the depletion of ozone layer?

  1. Carbon dI oxide

  2. Methane

  3. Cluroflorocarbon

  4. Sulphur di oxide
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation
Chlorofluorocarbons (CFCs
Chlorofluorocarbons (CFCs) and other halogenated ozone depleting substances (ODS) are mainly responsible for man-made chemical ozone depletion. The total amount of effective halogens (chlorine and bromine) in the stratosphere can be calculated and are known as the equivalent effective stratospheric chlorine (EESC).

The ozone layer protects the earth from harmful _________________.

  1. infared rays

  2. ultraviolet rays

  3. cosmetic rays

  4. gamma rays
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

Ultraviolet rays,

The ozone layer acts as a filter for the shorter wavelength and highly hazardous ultraviolet radiation (UVR) from the sun, protecting life on Earth from its potentially harmful effects. When the sky is clear, there is an inverse relationship between stratospheric ozone and solar UVR measured at the Earth's surface.

Multiple choice zoology bio-geo chemical cycles in nature nutrient cycles- flow of substances carbon cycle biogeochemical cycles - gaseous

The ozone at ground level is primarily from__________ precursors

  1. Fossil fuel
  2. $CFC _{S}$

  3. Oxygen

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

Ground-level ozone is a secondary pollutant formed by the reaction of nitrogen oxides and volatile organic compounds in the presence of sunlight, both of which are primarily emitted by fossil fuel combustion.

What are known as Sun Spots?

  1. Cooler regions on photosphere

  2. Hotter regions on photosphere

  3. Cooler regions on stratosphere

  4. Hotter regions on stratosphere
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Spots formed on the surface of the Sun that are darker and cooler are called the Sun's spots.

They may differ in size from small to large also.

The concentration of ozone in the troposphere is typically very low, often cited around 0.05 ppm in clean or background conditions.

Multiple choice biology concept of life theories of the origin of life origin of life the origin of cells and cell division

Atmosphere of earth just before the origin of life consisted of  ___________________.

  1. Water vapours, $CH _4 , NH _3 $ and Oxygen
  2. $ CH _4 , NH _3 $ and $CH _4$
  3. $ CO _2 , NH _3 , H _2 $ and water vapours
  4. $ CH _4 , O _3 , O _2 $ and water vapours
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

The Oparin-Haldane hypothesis suggests that the primitive atmosphere was reducing, containing methane, ammonia, hydrogen, and water vapor. Carbon dioxide is sometimes included in models of the early atmosphere.
