Which of the following is not a primary contributor to the greenhouse effect?

  1. chlorofluorocarbons

  2. carbon dioxide

  3. nitrous oxide

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

Trapping of sun’s heat in the lower atmosphere due to the presence of gases like water vapour, carbon dioxide, methane is called greenhouse effect.

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 trap the radiation from escaping. This causes an increase in earth’s temperature resulting in Global warming.

The two gases making highest relative contribution to the greenhouse gases are ____________________.

  1. methane and carbondioxide

  2. butane and carbondioxide

  3. propane and carbondioxide

  4. ethane and carbondioxide
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

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 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. 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 chemistry for a pollution free nature properties of soil soil pollution and its effects soil and soil pollution

The agricultural field that produces maximum methane gas into atmosphere is:

  1. wheat field

  2. paddy field

  3. cotton field

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

Rice is grown in flooded fields, a situation that depletes the soil of oxygen. Soils that are anaerobic (lacking oxygen) allow the bacteria that produce methane from decomposing organic matter to thrive. Some of this methane then bubbles to the surface, but most of it is diffused back into the atmosphere through the rice plants themselves. Hence, rice Paddy field that produces maximum methane gas into the atmosphere.

What are green house gases?

  1. Gases that trap heat in the atmosphere

  2. The gases produced by plants

  3. Gases that escape from volcano

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

Greenhouse gases, such as carbon dioxide and methane, absorb and emit radiant energy within the thermal infrared range, effectively trapping heat in the Earth's atmosphere.

Multiple choice zoology not for breathing not for drinking air pollution and its control air pollution - effects and control environmental issues

Which of the following decreases carbon dioxide levels in the atmosphere?

  1. Cellular Respiration

  2. Decomposition by bacteria

  3. Burning fossil fuels

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

During Photosynthesis plants i.e. leaves take in carbon dioxide (CO2CO2) to make glucose. This reduces the carbon dioxide in the atmosphere. This is why trees, grasses, and algae all are solutions to global warming caused by excessive carbon dioxide (CO2CO2). All three of the other processes involve taking in oxygen (O2O2) and releasing carbon dioxide (CO2CO2), thus increasing the carbon dioxide in the atmosphere.

So, the correct answer is 'Photosynthesis'.

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.'

  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.
