A Correct answer
Explanation

With the increase in population, the increasing need for space is also turning out to be an area of concern. With desperate need for land for agricultural, industrial and most importantly urban needs to contain cities and their growing population, a direct action that we have come to recognize as “Deforestation” occurs. Deforestation in simple term means the felling and clearing of forest cover or tree plantations in order to accommodate agricultural, industrial or urban use. It involves permanent end of forest cover to make that land available for residential, commercial or industrial purpose.

Overexploitation of resources results in ________.

  1. Desertification

  2. Pollution

  3. Water scarcity

  4. All of the above
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Overexploitation of resources is disturbing environment in many ways. Wasting water has far-reaching consequences, which include the destruction of aquatic environments, lack of agricultural productivity and scarcity of safe drinking water.  Wastage of water leads to water scarcity. Unplanned exploitation of environmental resources has caused a lot of havoc to man and his environment on one hand. Air pollution, pollution of water, dumping of waste etc are some of the results of an unplanned exploitation of environmental resources. Desertification at the global level is the reduction in biodiversity, as it contributes to the destruction of the habitats of animal and vegetal species and micro-organisms.

Use of water has been increasing more than ______ the rate of population increase in the last century.

  1. thrice

  2. twice

  3. half

  4. ten times
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation
Water use has been growing globally at more than twice the rate of population increase in the last century. By 2025, 1.8 billion people will be living in countries or regions with absolute water scarcity, and two-thirds of the world population could be under stress conditions.Water scarcity is both a natural and a human-made phenomenon. There is enough freshwater on the planet for seven billion people but it is distributed unevenly and too much of it is wasted, polluted and unsustainably managed.

Extreme mining leads to _____ pollution.

  1. ground

  2. water

  3. ground water

  4. all of the above
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation
The environmental impact of mining includes erosion, formation of sinkholes, loss of biodiversity, and contamination of soil, groundwater and surface water by chemicals from mining processes. Mining activities can lead to the generation of large quantities of heavy metal laden wastes which are released in an uncontrolled manner, causing widespread contamination of the ecosystem thus leading to pollution.

About ______ of the world's commercial energy comes from non-renewable fossil fuels.

  1. 50%

  2. 60%

  3. 70%

  4. 80%
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Most of our energy is derived from non-renewable sources. 80% of the world's commercial energy comes from fossil fuels i.e oil, coal and natural gas. As non-renewable resources, their use is clearly unsustainable. While these resources will still exist in the ground for many years, both the financial and energy costs of bringing them to market will become increasingly prohibitive as their supplies dwindle.

Which satellites help in finding and managing resources?

  1. Navigation satellites

  2. Communication satellites

  3. Remote sensing satellites

  4. Research satellites
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation
Remote sensing is the science of obtaining information about objects or areas from a distance, typically from aircraft or satellites. Remote sensing has a wide range of applications in many different fields i.e it helps in finding and managing various resources. For eg: Natural resource management: Remote sensing satellites helps to monitor land use, map wetlands, and chart wildlife habitats. Data collected can be used to minimize the damage that urban growth has on the environment and help to decide how to best protect natural resources.

Deforestation results in _________.

  1. Droughts

  2. Flooding

  3. Both A and B

  4. Earthquake
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

Forests naturally absorb water from rainfall and slowly release the water into the rivers. After deforestation, rainfall flows too quickly to the rivers, stripping the topsoil and causing erosion and flooding to occur. When these floods break the river's banks, further problems arise as the path of the river changes and further soil erosion occurs along the river's new path. Deforestation also makes an area more arid, contributing to droughts.

______ percent of the world's natural forests is destroyed by human development activities.

  1. 30

  2. 50

  3. 70

  4. 80
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

80% of the world's natural forests is destroyed by human development activities. Forests destruction by human activity is mainly for the purpose of harvesting natural resources for industry production and urbanization. Human activity is to blame for deforestation, though natural disasters do play a role. Clearing forests for agriculture is the principal cause for habitat destruction.
