A Correct answer
Explanation

Option A is the correct answer.

Methane absorbs heat from the sun very effectively and warms the atmosphere, and hence it is a major greenhouse gas

Multiple choice zoology bioenergy biogas environmental use of microorganism microbes in waste treatment and biogas

What does gobar gas produced from animal and plant waste contain?

  1. Ethane

  2. Methane

  3. Propane

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

Biogas is also commonly known as gobar gas. The biogas is produced due to anaerobic decomposition of the organic waste matter from the plants and animals with the help of microorganisms. The composition of biogas is methane and carbon dioxide. There are traces of hydrogen, nitrogen, hydrogen sulphide and carbon monoxide. The major component is of methane which accounts for 50-70%. Methane forms the clear and non-polluting gas and commonly used as a fuel.

Thus, the correct answer is option B.

Which one of the following is a major constituent of Biogas?

  1. Carbon dioxide

  2. Methane

  3. Hydrogen

  4. Nitrogen dioxide
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation
  • Biogas is a mixture of mostly methane and carbon dioxide with trace amounts of other gases and is considered as a valuable renewable energy source.
  • Methane comprises of 45-70% of biogas and thus biogas is inflammable. It produces a deep blue flame and can be used as an energy source.
Multiple choice chemistry group 17 group 17 - physical properties physical properties of group 17 elements group 17 elements: the halogen family

Which of the following is not a green house gas?

  1. $CO _2$
  2. $CH _4$
  3. $O _3$
  4. $N _2X$
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Greenhouse gases are gases in an atmosphere that absorbs and releases radiation This process is the cause of the greenhouse effect. The main greenhouse gases in Earth's atmosphere are water vapour, carbon dioxide, methane, nitrous oxide, and ozone. So $N _2X$ is not greenhouse gas.

Hence option $D$ is correct.

D Correct answer
Explanation

Green chemistry is a design of products and process that reduces or eliminates the use of harmful hazardous products. It uses the concept of invention and design and invokes to produce products that are environment-friendly.

Multiple choice zoology environmental factors environmental factors and their measurements climate factors marine life

Greenhouse gases are

  1. CO$ _{2}$
  2. CH$ _{4}$

  3. CFC

  4. All of these
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Green house gases (e.g. CO$ _{2}$, CH$ _{2}$, CFCs etc.) are increasing in the atmosphere due to human and natural activities. These gases trap the heat(infra-red radiation) reflected by the earth. This heats up the atmosphere(leads to an increase in earth's temperature). This phenomenon is called global warming which occurs due to green house effect.

Multiple choice zoology ecosystem : structure and function biogeochemical cycles - sedimentary biogeochemical cycle nitrogen and phosphorus cycles

Which is not a gaseous biogeochemical cycle?

  1. Sulphur

  2. Phosphorus

  3. Nitrogen

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

Biochemical cycle is also called as biogeochemical cycle or nutrient cycle. Biochemical cycle with gaseous phase includes various cycles like carbon cycle, nitrogen cycle, oxygen cycle. The nitrogen, carbon and oxygen are found in the gaseous form in the atmosphere. Calcium cycle, sodium cycle, phosphorous cycle, iron cycle, magnesium cycle, sulphur cycle are sedimentary cycles.

Thus, the correct answer is 'Sulphur and Phosphorus.'

 The concentration of which gas is highest in our environment?

  1. Nitrogen

  2. Hydrogen

  3. Carbon dioxide

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

Atmosphere consists of many different  gases like nitrogen, oxygen, carbon dioxide etc. Of all these gases nitrogen constitutes the major portion. Earth has 78.09% nitrogen, 20.95% oxygen, 0.93% argon, 0.04% carbon dioxide and other gases in minute proportion.

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.

Multiple choice business organisation and correspondence life is precious road safety and pollution pollution of natural resources air pollution and its effects

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'.
