Multiple choice biology living in harmony climate factors abiotic components organisms and environment

Rainfall pattern depends on

  1. The underground water table

  2. The number of water bodies in an area

  3. The density pattern of human population in an area

  4. Prevailing season in an area
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

The Rainfall pattern depends on the number of water bodies in an area because which area has more water bodies that area evaporates more water and this evaporation increases the precipitation water cycle and hence initiate  the rainfall 

So option 'b' the number of water bodies in an area is the correct answer.

What is the cause of a very high demand of water even though it is inexhaustible natural resource?

  1. Fresh water makes only small volume of world's water

  2. Most of the fresh water is in the form of ice and snow cover

  3. Conversion of sea water to fresh water is difficult and not economical

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

Water is inexhaustible natural resource .i.e. it is never going to deplete but it has a very high demand because the large percentage of water which is present on the Earth surface is not suitable for drinking. The suitable form is in the frozen form (ice, snow, glaciers etc). Its conversion to drinking water is non-economical and hence is not favoured.

Why is water a renewable resource?

  1. Water continuously evaporates.

  2. Man can create water.

  3. Use of water is minimum.

  4. The above statement is incorrect.
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

A renewable resource is any natural resource that replaces itself given enough time. The rate of replenishment must be equal to or faster than the rate of usage. As water continuously evaporates from the Earth's surface, it collects in the atmosphere to later come back to the Earth as rain. On the Earth itself surface water replenishes groundwater, and groundwater replaces surface water. With careful management and responsible usage, water is a renewable resource.

_____ is a method of conservation of water.

  1. Rainwater harvesting

  2. Rainwater dropping

  3. Rain planning

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

Rainwater harvesting is the accumulation and storage of rainwater for reuse on-site, rather than allowing it to run off. Rainwater can be collected from rivers or roofs, and in many places, the water collected is redirected to a deep pit, a reservoir with percolation. Its uses include water for gardens, livestock, irrigation, domestic use with proper treatment, indoor heating for houses, groundwater harvesting.

Cycle or walk is the method to conserve ___________ .

  1. fuels

  2. water
  3. both $A$ and $B$

  4. none of these
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation
Cycle is a human-powered, pedal-driven, single-track vehicle, having two wheels attached to a frame, one behind the other. A bicycle rider is called a cyclist, or bicyclist.

Walking also required muscular force. It is a form of mechanical work.
So both are used to conserve fuels.

Option A is correct.

Which one of the following is not an ideal solution for tackling water shortages?

  1. Controlling population growth

  2. Conserving water in irrigation

  3. Controlling water pollution

  4. Drilling large number of deep bore wells
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Drilling large number of deep bore wells,

It is not an ideal solution for tackling water shortage.
Rain water harvesting and ground water recharging is the need of the hour. Roof top rain water harvesting are being taken up in urban areas. In roof top harvesting u r to collect rain water and  using a filter clean it, then send it to the aquifer through a tube well or dug well. In open field u can recharge ground water storing the rain water in numerous tanks, ponds, contour  trench etc disallowing the rain water to drain to river and finally to ocean. If  tube wells are drilled inside the tanks and  ponds, more rain water can be recharged into the aquifer.

Floods can be prevented by:

  1. afforestation

  2. cutting the forests

  3. filling the land

  4. removing the top soil
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation
Afforestation means planting trees. 

As we know, the roots of the trees help to hold soil layer firmly.

It is evident that it helps not to make soil loose and prevents erosion. Thus, by planting more and more trees, the top layer of soil becomes less prone to erosion by wind, water or anything likely. 

Thus, it prevents erosion and helps in soil conservation.

Afforestation involves the planting of trees in a drainage basin to increase interception and storage while reducing surface runoff. This reduces a rivers discharge and so makes it less likely to flood.

Option A is correct.

For the production of hydro- electricity water must fall from a _______.

  1. Greater height

  2. Lesser height

  3. Both A and B

  4. Neither A nor B
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Hydroelectricity is electricity made by generators that are pushed by movement of water which falls from greater height. It is usually made with dams that block a river to make a reservoir or collect water that is pumped there. When the water is released, the pressure behind the dam forces the water down pipes that lead to a turbine. This causes the turbine to turn, which turns a generator which makes electricity.

Water power potential of India is great, but it has not been developed to its full extent. The major deterrant being that _______.

  1. Coal is available in plenty therefore it is not necessary to develop water power.

  2. Raw materials required for the production of electric transformers are not available in India.

  3. Rainfall is seasonal and as such requires costly storage resevoirs.

  4. Lack of technical skill hinders the development of water power.
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

India's rainfall is highly seasonal (monsoonal), meaning water flow is inconsistent throughout the year, necessitating expensive storage reservoirs to ensure year-round power generation.
