Multiple choice

What is good in absorbing warmth of the Earth?

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.

Multiple choice

Among the following climatic factors, which one has the least effect upon a terrestrial ecosystem?

  1. Temperature variation

  2. Wind

  3. Conditions of sunlight

  4. Availability of water
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

 Temperature variation is universally important environmental factor as each species has its own minimum, maximum and optimum temperatures for life. Condition of sunlight determines the source of energy for ecosystem. Besides most organisms need large amount of water to survive so wind has the least effect.

Multiple choice economics environment pollution environment and pollution for a pollution free nature natural resources- air, water and land

The increase in temperature on the earth disturbs the water cycle and reduces rainfall. The situation may lead to:

  1. floods

  2. droughts
  3. increased level of ${CO _2}$

  4. all of the above
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

The increase in temperature on the earth (due to deforestation - cutting down of trees) disturbs the water cycle and reduces rainfall. The situation may lead to droughts (high scarcity of water).

Multiple choice biology physical resources air and winds wind energy air as a natural resource

The average amount of CO$ _2$ in the atmosphere is

  1. 100 ppm

  2. 400 ppm

  3. 1000 ppm

  4. 10 ppm
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation
Carbon dioxide is an important gaseous component of the environment. It is fixed by the green plants by the process of photosynthesis. It is released during expiration by the process of respiration. As proclaimed by World Meteorological Organization, the average amount of carbon dioxide which can be passed globally by the atmosphere is 400 ppm. Increase in the carbon dioxide concentration may lead to global warming which is mainly caused due to human activities like deforestation.
So, the correct answer is option B.

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

In the future, climate change is likely to result in an increased chance of flash floods and coastal inundation. Australia’s growing population and urbanization are likely to place increased pressure on our waterways and to increase the chance of flooding in cities and the number of properties and people exposed to floodwaters.

Level of atmospheric $CO _2$ has increased in $2000$ from

  1. $280$ ppm to $360$ ppm
  2. $250$ ppm to $300$ ppm
  3. $300$ ppm to $340$ ppm
  4. $330$ ppm to $350$ ppm
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Carbon dioxide is the greenhouse gas. It means that it traps the insolation from the sun and does not allow them to be reflected back. The trapped insolation work in warming the overall temperature of the earth. The level of atmospheric CO$ _{2}$ was around 200 ppm during the ice age. It rose to 280 ppm during the warmer interglacial periods. Presently, in the Anthropocene era, due to the excessive CO$ _{2}$ releasing activities like fossil fuel burning, the level of CO$ _{2}$ has risen to 360 ppm.

Hence, the correct answer is '280 ppm to 360 ppm'
