Greenhouse Gases and Atmosphere Questions

Multiple choice types, sources and impact of waste accumulation waste management - impact of waste accumulation our life and environment geography

High _________ dioxide concentration causes global warming.

  1. Carbon

  2. Sulphur

  3. Nitrogen

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

  • High Carbon dioxide concentration causes global warming.
  • Trapping of sun’s heat in the lower atmosphere due to increase in the pollution causing gases like carbon dioxide is called greenhouse effect.
  • Greenhouse gases are water vapour, carbon dioxide, methane and ozone, nitrous oxide etc.
  • Sun’s radiation is partly absorbed by earth and rest of the radiations are reflected back to the atmosphere which are escaped. But the greenhouse gases form blanket in the atmosphere and traps the radiation from escaping. This causes an increase in earth’s temperature resulting in global warming.

Multiple choice botany energy flow in an ecosystem biogeochemical cycle nutrient cycles species, communities and ecosystems

A biogeochemical cycle without an atmospheric component is

  1. Sulphur

  2. Nitrogen

  3. Phosphorus

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

A biogeochemical cycle is also called as nutrient cycle. It is of various types such as sedimentary cycle, gaseous cycle. Sedimentary cycle consists of weathering of an existing rock followed by the erosion of minerals, transport and deposition. It has earth's crust as the reservoir pool. The sulphur cycle is a sedimentary cycle without an atmospheric component. 

Thus, the correct answer is 'Sulphur.'

Multiple choice our life and environment geography

Thermal power plants emit large quantities of _________which is a greenhouse gas

  1. carbon monoxide

  2. carbon dioxide

  3. nitrogen oxide

  4. both A and C
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

Thermal power plants burning fossil fuels release large amounts of carbon dioxide, which is the primary greenhouse gas.

Multiple choice geography what is around us? atmosphere and its structures the atmosphere components of earth elements of weather and climate : temperature the earth's structure

Tick the correct answer.
The major constituent of atmosphere by percent is

  1. Nitrogen

  2. Oxygen

  3. Carbon dioxide

  4. None of these
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

The atmosphere is composed mainly of nitrogen and oxygen, which make up about 99 per cent of clean, dry air. Nitrogen 78 per cent, oxygen 21 per cent and other gases like carbondioxide, argon and others comprise 1 per cent by volume. 

Multiple choice evs - i what is around us? atmosphere and its structures the atmosphere components of earth elements of weather and climate : temperature the earth's structure

Gases which increase the temperature of the atmosphere such as carbon dioxide, methane, chlorofluorocarbon, etc are known as ___ gases.

  1. Green house

  2. Blue house

  3. White house

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

Greenhouse gases,

Some greenhouse gases occur naturally and enter the atmosphere as a result of both natural processes (such as decomposition of organic matter) and human activity (such as burning fossil fuels and agriculture). Greenhouse gases that occur both naturally and from human activities include water vapor, carbon dioxide (CO2), methane (CH4), nitrous oxide (N2O) and ozone (O3). Other greenhouse gases have essentially no natural sources, but are side products of industrial processes or manufactured for human purposes such as cleaning agents, refrigerants, and electrical insulators. These include the fluorinated gases: chlorofluorocarbons (CFCs), hydrochlorofluorocarbons (HCFCs), hydrofluorocarbons (HCFCs), bromofluorocarbons (halons), perfluorocarbons, PFCs, nitrogen trifluoride, NF3, and sulfur hexafluoride, SF6.

These gases contribute to atmospheric warming when they absorb infrared radiation emitted by the solar-warmed Earth and transfer their extra energy to the surrounding atmospheric gases.

The main component of natural gas is?

  1. Carbon dioxide

  2. Carbon monoxide

  3. Oxygen

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

Natural gas is a naturally occurring, flammable gas comprising largely of methane and other hydrocarbons. It is a source of fuel and formed underground.

Multiple choice biology biogeochemical cycles carbon cycling mineral coal carbon cycle

Which of the following gases has role an important in maintaining atmospheric temperature?

  1. Nitrogen

  2. Oxygen

  3. Argon

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

Carbon dioxide is a greenhouse gas that traps heat in the atmosphere, playing a critical role in maintaining the Earth's temperature. Nitrogen and oxygen are the primary components of air but do not have the same greenhouse effect.

Major 'reservoirs' of $CO _{2}$ are:

  1. Land, water, plants

  2. Fossil fuel, soil, , oceans

  3. Volcanic Eruption

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

Carbon is stored in major reservoirs including the atmosphere, oceans, soil, and fossil fuels. These act as sinks or sources for carbon exchange.

Multiple choice biology through the alimentary canal guttation excretion in plants long distance transport of water

The main waste products of plants are

  1. CO$ _2$ and NO$ _2$.
  2. CO$ _2$ and water vapour.
  3. CO$ _2$, O$ _2$ and water vapour.

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

Plants eliminate some waste through diffusion. During the day, excess oxygen gas produced by photosynthesis is released through the stomata. Carbon dioxide produced by respiration is normally used up during photosynthesis. At night, however, as photosynthesis slows, carbon dioxide is not used up as fast as it is produced, and it is released as a waste product. Plants also release waste water by transpiration and guttation. 

Therefore, the correct answer is option C.

The third most abundant gas in Earth's atmosphere is:

  1. carbon

  2. nitrogen

  3. oxygen

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

The atmosphere contains many gases, including some pollutants and greenhouse gases. The most abundant gas in the atmosphere is nitrogen, second oxygen . Argon, an inert gas, is the third most abundant gas in the atmosphere.
