Climate Change Impacts Questions

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

The nature of soil refers to its composition and texture, which don't influence air temperature. Pollution affects temperature through urban heat islands, trees provide shade and cooling, and population density correlates with heat generation. Soil composition is primarily relevant for plant growth, not thermal conditions.

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 pattern averaged over a long period (typically 30+ years), not momentary conditions. Weather refers to short-term atmospheric state at a specific time and place. Climate represents the enduring, predictable patterns that characterize a region's environmental conditions.

Multiple choice

Which of the following factors does not affect the climate of the earth?

  1. Distance from sun

  2. Earth's shape

  3. Earth's tilt

  4. Distance from equator
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

The Earth's SHAPE does not affect climate - the Earth is roughly spherical and this shape itself doesn't determine climate patterns. What DOES affect climate includes: distance from the sun (affects solar energy received), Earth's tilt (23.5° - causes seasons), distance from equator (latitude - determines climate zones). Other factors include ocean currents, altitude, and wind patterns. The spherical shape itself is not a climate-determining factor.

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

Affect

Directions: Some words in the passage below have been highlighted. Select the best meaning for the corresponding word.

All animal life on planet earth depends on sufficient supply of oxygen for its day-to-day survival. The trees that now just sporadically dot our landscapes, but once heavily blanketed earth’s surface, still are able to provide a large portion of oxygen supply. Through a process of photosynthesis, trees take in carbon dioxide from surrounding air and in return create a sizeable amount of oxygen. Ironically, human beings, who cut down large number of trees to create land, shelter, and energy, pose the most significant threat to survival of world–wide tree population.
But humans are not the only forces that threaten the survival of these mighty members of plant kingdom. Lighting, fire, volcanoes and earthquakes not only destroy many square miles of old growth forest in a matter of hours but may prevent new trees from going. Disease causing fungi and insect pests can either eradicate certain types of trees or weaken their branches.     
Climate also determines whether particular species of tree will prosper in a given area. Amount of rainfall and range of temperature also affect distribution of tree species.

  1. Impact

  2. Fake

  3. Change

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

The passage states that rainfall and temperature 'affect distribution of tree species.' In this context, affect means to influence or make a difference to. 'Impact' is the correct synonym here - to have an effect on or influence something. The climate conditions influence where trees can grow.

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 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.
