Nitric oxide also reacts with the ozone in the earths atmosphere to form:

  1. nitrous acid

  2. nitrogen dioxide

  3. nitric acid

  4. all of above
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

Dinitrogen and dioxygen are the main constituents of air, and they form nitric oxide and nitrogen dioxide in high temperature. Nitric oxide also reacts with the ozone in the earths atmosphere to form nitrogen dioxide.

Multiple choice geography temperature process of heat transfer in the atmosphere temperature and insolation sun: the ultimate source

Gases like ______ prevent the escaping radiation of heat from the earth.

  1. Carbondioxide

  2. Carbonmonoxide

  3. Nitrogen

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

Carbon dioxide is a greenhouse gas, which prevents the escaping of heat from the earth.

Greenhouse Gases. Earth's atmosphere is composed primarily of nitrogen and oxygen. These gases are transparent to incoming solar radiation. They are also transparent to outgoing infrared radiation, which means that they do not absorb or emit solar or infrared radiation.

Majority of meteriorites burn and disintegrate in

  1. Mesosphere

  2. Thermosphere

  3. Stratosphere

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

The mesosphere is the layer of the atmosphere where most meteoroids burn up upon entry due to friction with atmospheric gases.

Multiple choice

The cycle of water is essential for life on our planet as it is related with the four layers of the earth, which are...

  1. Geosphere, atmosphere, hydrosphere and core

  2. Geosphere, biosphere, atmosphere and crust

  3. Geosphere, biosphere, atmosphere and troposphere

  4. Geosphere,atmosphere , hydrosphere and biosphere
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

The water cycle interacts with the four main spheres of the Earth: the Geosphere (land), Atmosphere (air), Hydrosphere (water), and Biosphere (living organisms).

Multiple choice geography pollution - types and sources environmental risks of economic development tundra climatic region effects and successes of environment conservation

The depletion in the Ozone layer is caused by _________.

  1. carbon dioxide

  2. nitrous oxide.

  3. methane.

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

Ozone is a protective blanket that is present in stratosphere which protects earth from harmful effects of UV radiations that are present in sun light.

Chlorofluorocarbons and other halogenated compounds cause ozone depletion.

Chlorofluorocarbons are anthropogenic and are released from air-conditioning, refrigeration, blowing agents in foams, insulation and packing materials, propellants in aerosol cans, and as solvents.

What is the harm from the depletion of Earth's ozone layer ________________.

  1. The oxygen content of the atmosphere will decrease

  2. The average temperature of earth's surface will increase gradually

  3. Sea levels will rise as the polar ice caps will gradually melt

  4. Increased amount of Ultra violet radiation will reach earth's surface

D Correct answer
Explanation

Depletion of Earth's ozone layer results in increased amount of Ultra violet radiation will reach earth's surface

Ozone is a protective blanket that is present in stratosphere which protects earth from harmful effects of UV radiations that are present in sun light.

Multiple choice biology aids to health immunization, treatment and antibiotics antibodies and antitoxin prevention and treatment of disease

Ozone is passed through swimming pool because it

  1. Absorbs UV radiations

  2. Acts as disinfectant
  3. Easily available from $O _2$

  4. All of the above
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

Ozone is an effective disinfectant. It is passed through the swimming pool and is used in water treatment units because of the following reasons:

1. It improves the smell and visibility of the water.
2. It destroys bacteria and viruses by causing their oxidation.
3. It oxidises metals like manganese, iron and sulphur into the soluble particles and so these can be easily filtered out.
4. It has a bleaching effect on the discoloured water.
Hence, the correct answer is 'Acts as disinfectant'.

Exchange of incoming and outgoing radiation that keep the earth warm is known as

  1. Global warming

  2. Ozone layer depletion

  3. Green house effect

  4. Radiation effect
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

The greenhouse effect is the process by which radiation from a planet's atmosphere warms the planet's surface to a temperature above what it would be without its atmosphere.

Multiple choice geography environmental changes elements of weather and climate : temperature process of heat transfer in the atmosphere environmental regions (zones)

What percent of the insolation is reflected back to space by dust and clouds present in the atmosphere?

  1. 30%

  2. 35%

  3. 40%

  4. 45%
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

About one third i.e 35% of the solar energy is reflected back (like a mirror reflecting light) by the Earth’s atmosphere. Further, some portion of the light is scattered and absorbed in the higher reaches of the atmosphere. In fact, some of the harmful rays of Sun like the UV rays don’t reach the ground and this has made life possible on the Earth.
