Climate Change Impacts Questions

Multiple choice

Which of the following correctly defines climate?

  1. A change in the atmospheric condition

  2. Weather of a place over a long period of time

  3. General conditions of atmosphere at a particular time and place

  4. Temperature at a particular region
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

Climate is defined as the weather conditions prevailing in an area over a long period of time (typically 30+ years). It represents long-term patterns of temperature, humidity, rainfall, etc. Option A describes change in atmospheric conditions (too vague). Option C describes weather at a particular time and place (that's WEATHER, not climate). Option D only mentions temperature (climate includes multiple elements). Only option B correctly captures the time aspect essential to climate definition.

Multiple choice

Which of the following factors does not affect the temperature of a particular region?

  1. Pollution

  2. Number of trees

  3. Density of population

  4. Nature of soil
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Pollution creates urban heat islands, making cities warmer. Trees provide shade and release cooling moisture through transpiration. Population density increases temperature through concentrated human activities and heat generation. Soil nature affects surface heat absorption but has minimal impact on regional air temperature compared to the other factors.

Multiple choice

One of the most harmful effects of global warming is:

  1. decay of different materials like modern buildings, statues, roads due to rising temperature

  2. hurricanes become more frequent & stronger

  3. increased rate of green house gases in air, which forms large hole in ozone (O3) layer

  4. earth is tilted at angle 23.50

  5. warming up of the environment due to increase in the use of fossil fuel in different industries
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

The most harmful effects of global warming is increased rate of green house gases in air that results in formation of a large hole in ozone (O3) layer called O3-hole.

Multiple choice

Which of the following will occur due to depletion of ozone layer?

  1. Increase in temperature of earth

  2. Decrease in oxygen content of atmosphere.

  3. Increased amount of UV radiation reaching earth

  4. Rise in sea levels and melting of glaciers

  5. Acid rain
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

 Ozone layer prevents ultravoilet rays from reaching earth's surface. Depletion of ozone layer will lead to increased amount of UV raus reaching earth's surface.

Multiple choice

Assertion(A): Farmenetal reported that from 1875 to 1985, a reduction of 40% to 50% of ozone content over Antartica occured, reaching Southern New Zealand, Australia and Southern America. Reasoning (R): Ozone layer thinning in the stratosphere directly influences the increase in global warming.

  1. Both Assertion and Reasoning are true and R is the correct explanation of A.

  2. Both Assertion and Reasoning are true and R is not the correct explanation of A.

  3. A is true and R is false.

  4. Both A and R are false.
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Ozone layer thinning in the stratosphere increases global warming due to the penetration of UV rays through the ozone layer.

Multiple choice

Which of the following statements is/are false? a. Trapping of heat rays by carbon dioxide increases the temperature of Earth's atmosphere, leading to global warming. b. Due to global warming, polar ice caps melt rapidly, resulting in the rise of sea level. c. The lower layer of soil has more humus and is thus, more fertile.

  1. Only a

  2. Only a and b

  3. Only b

  4. Only b and c

  5. Only c
Reveal answer Fill a bubble to check yourself
E Correct answer
Explanation

Statement 'c' is a wrong statement. The lower layer of soil has less humus and is thus, less fertile.

Multiple choice

Which of the following options correctly describes greenhouse effect?

  1. The retention of heat energy by greenhouse gases

  2. When rainwater becomes acidic due to the presence of sulphur and nitogen

  3. Planting of trees in order to reduce air pollution

  4. The release of oxygen during photosynthesis

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

The retention of heat energy by carbon dioxide and other greenhouse gases like cholorofluorocarbons, methane, water vapour and  oxides of nitrogen, which are present in the atmosphere, is called greenhouse effect.

Multiple choice

What effect will increased wind speed have on accompanying air pressure?

  1. The air pressure will also increase.

  2. The air pressure will also reduce.

  3. The air pressure will see moderate changes depending on the climate of the place.

  4. No change in air pressure can be ascertained.

  5. The air pressure has no relation whatsoever with wind speed.
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

Correct. Air moves from the region where the air pressure is high to the region where the pressure is low. The greater the difference in pressure, the faster the air moves. Thus, increased wind speed is, indeed, accompanied by a reduced air pressure.

Multiple choice

Which of the following is the reason for the release of greenhouse gases?

Directions: Read the folllowing passage and answer the question that follows.

Global warming is the term used to describe a gradual increase in the average temperature of Earth's atmosphere and its oceans, a change that is believed to be permanently changing Earth’s climate. There is great debate among many people and sometimes in the news, on whether global warming is real (some call it a hoax). But climate scientists looking at the data and facts agree the planet is warming. While many view the effects of global warming to be more substantial and more rapidly occurring than others do, the scientific consensus on climatic changes related to global warming is that the average temperature of Earth has risen between 0.4 and 0.8°C over the past 100 years. The increased volumes of carbon dioxide and other greenhouse gases released by the burning of fossil fuels, land clearing, agriculture, and other human activities, are believed to be the primary sources of the global warming that has occurred over the past 50 years. Scientists from the Intergovernmental Panel on Climate carrying out global warming research have recently predicted that average global temperatures could increase between 1.4°C and 5.8°C by the year 2100. Changes resulting from global warming may include rising sea levels due to the melting of the polar ice caps, as well as an increase in occurrence and severity of storms and other severe weather events.

  1. Forestation

  2. Increase in temperature

  3. Burning of fossil fuels

  4. None of these
