evs animal- the base of our life uses of animals agro-complimentary occupations improvement of crop production animal husbandry

  1. Goat

  2. Sheep

  3. Rabbit

  4. Fox

Show answer
Correct Option: C
Explanation:

Angora hair or Angora fibre refers to the downy coat produced by the Angora rabbit. While their names are similar, Angora fibre is distinct from mohair, which comes from the Angora goat. Angora fibre is also distinct from cashmere, which comes from the cashmere goat. Angora is known for its softness, thin fibres, and what knitters refer to as a halo (fluffiness). It is also known for its silky texture. It is much warmer and lighter than wool due to the hollow core of the angora fibre. It also gives them their characteristic floating feel. Yarns of 100% angora are typically used as accents. They have the most halo and warmth, but can felt very easily through abrasion and humidity and can be excessively warm in a finished garment. The fibre is normally blended with wool to give the yarn elasticity, as Angora fibre is not naturally elastic. The blend decreases the softness and halo as well as the price of the finished object. Commercial knitting yarns typically use 30–50% angora, in order to produce some halo, warmth, and softness without the side effects of excessive felting.

So the correct option is 'rabbit'.

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

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

  1. True

  2. False

Show answer
Correct Option: A
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'.

The process by which water from the surface of the earth moves to the atmosphere is:

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

  1. cooling.

  2. distillation.

  3. evaporation.

  4. None of the above.

Show answer
Correct Option: C
Explanation:

The process by which water from the surface of the earth moves to the atmosphere is evaporation.

95% of the Earths water is stored in its:

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

  1. glaciers

  2. oceans

  3. rivers

  4. ponds

Show answer
Correct Option: B
Explanation:

95% of the Earth's water is stored in its oceans, from where the water cycle starts. 

In water cycle, the maximum vaporization takes place:

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

  1. from oceans

  2. from rivers

  3. from streams

  4. from plants

Show answer
Correct Option: A
Explanation:

86% of global evaporation occurs from the ocean due to its large surface area which directly comes in contact with sun rays and gives maximum vaporisation.


Hence, option A is correct.

Which of the following is not naturally occurring form of water?

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

  1. Solid

  2. Liquid

  3. Vapour

  4. Semi-solid

Show answer
Correct Option: D
Explanation:

Water exists in liquid form upto  $100^0$C , at 100$^0$C it exists as vapour and at 4$^0$C it exists in solid form  as ice. So water exists in all the states or forms except semisolid, jelly state

So, the correct answer is 'Semi-solid'

Water is an extremely stable ____________.

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

  1. atom

  2. element

  3. mixture

  4. compound

Show answer
Correct Option: D
Explanation:

Water is a stable compound. Components made up of two or more elements is called a compound. Water is made up of two elements namely hydrogen and oxygen.

Water produces hydrogen and oxygen in the ratio of :

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

  1. 1:1

  2. 2:1

  3. 1:2

  4. 2:3

Show answer
Correct Option: B
Explanation:

Water molecular formula is $H _2O$. Water has 2 hydrogen and one oxygen atom. So it produces hydrogen and oxygen in the ratio 2:1.
