Climate Change Impacts Questions

Multiple choice

Climate means the average pattern in which the weather changes with time. Which of the following is not a factor that determines the climate of a place?

  1. The amount of sunshine that particular place gets

  2. The ability to transfer water to the atmosphere

  3. Whether the place is hilly or a plain region

  4. The presence or absence of rainfall

  5. The amount of water logging at that particular place

E Correct answer
Explanation

This is the correct option. The climate of a particular place is not determined by the amount of water logging at that particular place.

Multiple choice

Global warming has resulted due to

  1. increased level of oxides of sulphur and nitrogen.

  2. increased emissions of CO2 from automobiles.

  3. increased emissions of fine particulates from automobiles.

  4. increased flatulence of animals.
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

Global warming has resulted due to increased emissions of CO2 from automobiles. The main cause of it is greenhouse effect. Naturally occurring amounts of greenhouse gases have a mean warming effect of about 33 °C (59 °F). The major greenhouse gas is carbon dioxide (CO2) which causes 9-26% of greenhouse effect.

Multiple choice

As a result of rising global temperatures following two major impacts are expected

  1. rise in the sea level and regional climatic changes.

  2. increased water levels in water bodies like lakes and streams but more consistent flooding patterns.

  3. relatively long summers and drier winters.

  4. increased water levels in lakes and streams and comparatively larger floodplains.

A Correct answer
Explanation

Rise in the sea level and regional climatic changes are the two major impacts expected, as a result of rising global temperatures. An increase in global temperature will cause sea levels to rise and will change the amount and pattern of precipitation, as well as cause a probable expansion of subtropical deserts. 

Multiple choice

Rising global temperatures will lead to

  1. longer summers and drier winters

  2. higher water levels in lakes and streams and more consistent flooding patterns

  3. regional climatic changes and a rise in sea level

  4. low water levels in lakes and streams and larger floodplains

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

Rising global temperatures will lead to regional climatic changes and a rise in sea level. Global warming is the rise in the average temperature of Earth's atmosphere and oceans since the late 19th century, and its projected continuation. 

Multiple choice

Polar ice caps develop huge cracks because

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

When vegetation sprouts in the desert, it is a good sign but when the ice in the Arctic and Antarctic begins to turn green, there is something terribly wrong. Reports say that an iceberg, approximately the size of New York city, has broken off from the icy continent. An Argentine team discovered huge cracks in the polar ice caps. These developments can have serious implications. If polar ice fields melt, our coastal cities might be submerged, and sea levels across the world could rise between 3. 65 and 6. 09 metres in different parts of the earth. This is probably due to global warming.

  1. of the movement of the earth

  2. of the breaking off of icebergs

  3. of the crowding of cities like New York

2nd last line of the passage

Multiple choice

Greenhouse effect refers to which of the following?

  1. Cooling of earth

  2. Trapping of UV rays

  3. Production of cereals

  4. Warming of earth

  5. -
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

The greenhouse effect is the process by which radiation from a planet's atmosphere warms the planet's surface to a temperature above what it would be without its atmosphere. If a planet's atmosphere contains radioactively active gases (greenhouse gases), the atmosphere will radiate energy in all directions.

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

Explanation

Climate change will lead to rise in the sea level, inundation of coastal areas and subduction of biological hotspots, like coral reefs, etc.

Multiple choice

When does Global Warming occur?

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

Global Warming occurs when the concentration of greenhouse gases increases in the atmosphere. The main greenhouse gases are water vapour, carbon dioxide, methane, nitrous oxide and ozone. These gases stop all the radiations from the Earth to escape back into space. This is known as the Greenhouse Effect. This trapped radiation or heat helps to keep the Earth at a constant temperature. Greenhouse effect plays a very important role in maintaining the temperature of the Earth at a habitable level. For the last 100 years, human have been burning trees and fossil fuels, thereby releasing millions of tons of carbon dioxide into the atmosphere. Due to increase in level of carbon dioxide the temperature of the earth’s surface rises. This, in turn, causes more water to evaporate into the atmosphere. Water vapour is also very good at absorbing heat. This causes the Earth’s atmosphere to become even warmer. Scientist has called this effect ‘Global Warming’. They have warned that Global Warming could change rainfall patterns, raise the sea level and disturb the ecological balance.

  1. When the earth becomes hot
