Multiple choice biology global environmental change causes of greenhouse effect greenhouse effect pollution and its effects

Green house effect is increase in temperature of earth due to

  1. High concentration of $NO _2$
  2. High concentration of $SO _2$
  3. High concentration of $CO _2$

  4. High concentration of CO
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation
The warming of earth's surface when sun radiations are absorbed and trapped in earth's atmosphere, is called greenhouse effect. The gases responsible for green house effect are called green house gases which trap the radiations and don't let them reflect back from the earth's surface. The green house gases are Chlorofluorocarbons (CFC's), Carbon dioxide (CO2), Methane (CH4) and Nitrous Oxide (N2O). 
The approximate percentage of different greenhouse gases in the atmosphere is:
CFCs - 14%
CO2 - 60%
‎CH4 - 20%
N2O - 6%
Among all these gases, concentration of CO2 is highest. It is the main greenhouse gas.
So, the correct answer is 'High concentration of CO2'.
Multiple choice biology global environmental change causes of greenhouse effect greenhouse effect pollution and its effects

Why do scientists think that human-induced global warming will be more harmful to plants and animals than were past, natural climate fluctuations?

  1. because temperature will change faster

  2. because the temperature changes will be larger

  3. because species now are less adaptable than species in the past

  4. because ecosystems are now more complicated than they used to be
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Global warming is the increase in temperature of earth due to the increased concentration of greenhouse gases in the atmosphere. Temperature change due to global warming is faster than the temperature change due to natural climate fluctuations. This has resulted in melting of ice glaciers which will lead to rising in sea level and also the amount of freshwater will decline. Abnormal increase in temperature due to global warming has resulted in the extinction of many plant and animal species because of habitat loss and extreme climatic conditions.

So, the correct answer is 'because the temperature will change faster'.

Multiple choice biology global environmental change causes of greenhouse effect greenhouse effect pollution and its effects

Green house effect means

  1. Increase in the temperature of earth due to high concentration of NO$ _2$
  2. Increase in the temperature of earth due to high concentration of SO$ _2$

  3. Increase in the temperature of earth due to high concentration of CO
  4. Increase in the temperature of earth due to high concentration of CO$ _2$
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

  • Greenhouse effect increases the temperature of the earth. The gases responsible for greenhouse traps the infrared radiations which lead to heating of the earth's surface. 

  • The primary greenhouse gases in the earth's atmosphere are water vapor, carbon dioxide, methane, nitrous oxide, and ozone. 
Thus, the correct answer is option D.

Multiple choice biology global environmental change causes of greenhouse effect greenhouse effect pollution and its effects

World climate is threatened by increase in the concentration of

  1. Oxygen

  2. Nitrogen

  3. Water vapours

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

Level of carbon dioxide is continuously increasing in the air due to its constant release by burning of fossil fuels in automobiles, industries etc. As a result, the temperature of the earth is on a constant rise. This has led to global warming and the greenhouse effect. The ozone layer is getting depleted causing harmful UV rays to reach the earth and cause serious ill effects. Apart from this, glaciers are constantly melting due to increase in temperature.

So, option D " Carbon dioxide" is the correct answer.

Multiple choice biology global environmental change causes of greenhouse effect greenhouse effect pollution and its effects

The reason for green-house effect is

  1. Higher $CO _2$ concentration causing global warming

  2. Absorption of infra-red rays by gases and dust particles

  3. Both A and B
  4. Rarefaction of $CO _2$
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation
A minor but very important component of atmospheric carbon dioxide is released through natural process viz., Respiration, volcanic eruption. Humanly induced activities as deforestation, burning fossils, land use changes are major causes for the release of greenhouse gases in the atmosphere.
The greenhouse gases absorb infrared radiation from the sun and trap some of the radiation. Excess of these gases can force climate change drastically.
Hence, the correct answer is 'Both A and B'.
Multiple choice biology global environmental change causes of greenhouse effect greenhouse effect pollution and its effects

Green house effect is warming due to

  1. Infra-red rays reaching earth

  2. Moisture layer in atmosphere

  3. Increase in temperature due to increase in carbon dioxide concentration of atmosphere

  4. Ozone layer of atmosphere
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

Greenhouse effect refers to the absorption of the sun's radiations by the atmospheric gases like carbon dioxide and trapping of these radiations within the atmosphere. These are subsequently reflected onto the earth's surface and cause an increase in the global temperature, called global warming. Infra-red radiations reaching earth will not increase the temperature. Moisture layer in the atmosphere does not show the greenhouse effect. Ozone layer in atmosphere absorbs the UV within stratosphere so that they do not reach the earth's surface.

Hence, the correct answer is 'Increase in temperature due to increase in carbon dioxide concentration of atmosphere'

Multiple choice

A Correct answer
Explanation

Change in global or regional climatic patterns is called climate change. The main impact of climate change is the increase in sea level. This is because of melting of ice due to increase of global temperature as a result of climatic change.

Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Cryogenic is nothing but the quantities that are involved with very low temperatures like ice. Among the given options ice sheets and ice chores are the examples of cryogenic indicators of climate change because ice and glaciers react to atmospheric changes and give clear signals about alterations in global climate.
