Water Conservation and Management Questions

Multiple choice

A sprinkler irrigation system is suitable when

  1. the land gradient is steep and the soil is easily erodible

  2. the soil is having low permeability

  3. the water table is low

  4. the crops to be grown have deep roots
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

 Sprinkler irrigation has the highest efficient method of irrigation for the land having high gradient and soil is likely to be eroded due to flow of water but not suitable at high wind speed.

Multiple choice

What do you mean by irrigation?

  1. An artificial supply of water and fertilizer.

  2. An artificial supply of water to fields.

  3. A natural supply of water through rain.

  4. A collection of excess water from fields.
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

Irrigation means an artificial supply of water to plants.

Multiple choice

The sun drives the water cycle by

  1. heating the ocean

  2. rotating on its axis

  3. giving light to plants
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

The sun provides the thermal energy necessary to heat the Earth's surface, particularly the oceans, which causes water to evaporate and fuels the water cycle.

Multiple choice

The amount of water in the Great Lakes is enough to...

  1. Submerge the continental U.S. in 3 feet of water

  2. Make a 1 footx1 foot column of water all the way to the moon

  3. Cover Africa in 7 inches of water

  4. Create a glacier the same size of Antartica
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

The Great Lakes contain a massive volume of fresh water. It is estimated that if this water were spread evenly across the continental United States, it would cover the entire landmass in approximately 3 feet of water.

Multiple choice

What is the Sun's role in the water cycle?

  1. To provide the light energy for the cycle

  2. To provide mechanical energy for the cycle

  3. To provide the thermal energy to drive the cycle

  4. To cause water to condense in the cycle
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

The Sun provides the thermal energy (heat) required to evaporate water from oceans and lakes, which is the primary driver of the water cycle.

Multiple choice evs sources of water and water cycle groundwater and depletion of water table rain: where does it come from availability and forms of water the water cycle

The freshwater stored in the ground is much more than that present in the rivers and lakes of the world.

  1. True

  2. False
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation
  • Groundwater is the water found underground in the cracks and spaces in soil, sand, and rock. It is stored in and moves slowly through geologic formations of soil, sand, and rocks called aquifers.
  • Groundwater is the source of about 33 % of the water that county and city water departments supply to households and businesses (public supply).
  • Hence The freshwater stored in the ground is much more than that present in the rivers and lakes of the world is a true statement.
  • So, the correct answer is 'True'.
Multiple choice social science water: a precious resource sources of water and water cycle groundwater and depletion of water table water table the water cycle

Which of the following is mostly used as a drinking water source by us?

  1. Sea water

  2. Glaciers

  3. Ground water

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

Groundwater is mostly used as drinking water source by us. 

Sea-water contains dissolved salt in it, hence it is not generally used for drinking purposes unless purified. 
Hence, the answer is C.

Multiple choice social science water: a precious resource sources of water and water cycle groundwater and depletion of water table water table the water cycle

A depletion in the water table of a place is caused by which of the following?

  1. Constructing factories and houses

  2. Making concrete roads and floors

  3. Deforestation

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

Constructing factories and houses involve a large scale of deforestation. Due to deforestation, the soil will not remain intact due to which the water holding capacity of the soil decreases which causes a depletion in the water table. Making of concrete floors and roads do not allow the rainwater to seep through the soil and therefore causes a fall in the level of the water table.


Hence, the correct option is $\text{D}$

Well water is an example of:

  1. surface water

  2. rain water

  3. underground water

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

Well water is an example of underground water. A water well is an excavation or structure created in the ground by digging, driving and or drilling to access ground water in underground aquifers. The well water is drawn by a pump or using containers such as buckets that are raised mechanically or by hand.

Multiple choice evs sources of water and water cycle groundwater and depletion of water table rain: where does it come from availability and forms of water the water cycle

Rainfall patterns depend 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. The prevailing season in an area.
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

Rainfall pattern will depend on number of water bodies in an area, as there will be large water bodies, (ocean, river) the rate of evaporation would be high, which will help to cause rain in the area.
