The solid form of water is known as:

chemistry rain: where does it come from sources of water and water cycle availability and forms of water the water cycle

  1. fog

  2. dry ice

  3. ice

  4. snow

Show answer
Correct Option: C
Explanation:

The solid form of water is known as ice.

Evaporation is defined as:

chemistry rain: where does it come from sources of water and water cycle availability and forms of water the water cycle

  1. conversion of ice in water.

  2. conversion of water into water vapours.

  3. conversion of water vapours into the water.

  4. freezing of water into ice.

Show answer
Correct Option: B
Explanation:

When water is heated it absorbs energy and changes its state from liquid (water) to gas(water vapours). This process of converting water in vapours is known as vaporisation.

Which of the following processes is unsuitable for softening water possessing temporary hardness?

biology rain: where does it come from sources of water and water cycle availability and forms of water the water cycle

  1. Adding calcium hydroxide

  2. Filtration

  3. Boiling

  4. Distillation

Show answer
Correct Option: A
Explanation:

If you added calcium oxide to water, it would react and make calcium hydroxide. Calcium hydroxide is produced, however, when calcium oxide is mixed (or slaked) with water. Overall, nothing significant happens when you mic Ca(OH)2 with water, certainly no reaction occurs. So, the correct option is "A" (Adding calcium hydroxide).

Which of the following is the most important factor in balancing the amount of freshwater on earth?

evs rain: where does it come from sources of water and water cycle availability and forms of water the water cycle

  1. Water cycle

  2. Greenhouse effect

  3. Waste water treatment plant 

  4. Transpiration

Show answer
Correct Option: A
Explanation:

Water cycle is a continuous cycle in which water changes from water vapour in the atmosphere, through liquid water through condensation and precipitation and then back to water vapour through evaporation, transpiration and respiration. 

Among the given options, $A$ is the correct one. 

When water circulates through the water cycle it can be found in all the _________ form, at any given time somewhere on the earth.

evs rain: where does it come from sources of water and water cycle availability and forms of water the water cycle

  1. four

  2. two

  3. three

  4. six

Show answer
Correct Option: C
Explanation:

When water circulates through the water cycle it can be found in all the three forms, i.e., solid, liquid and gas at any given time somewhere on the earth. This continuous cycling of water in its three forms in nature keeps the total amount of water on earth constant even when the whole world is using it.

The circulation of water from surface of the earth to atmosphere and back to the surface is known as:

evs rain: where does it come from sources of water and water cycle availability and forms of water the water cycle

  1. water circle.

  2. water cycle.

  3. water round.

  4. None of the above.

Show answer
Correct Option: B
Explanation:

The circulation of water from surface of the earth to atmosphere and back to the surface is known as water cycle.

During water cycle, the water is circulated back from the earth in the form of:

evs rain: where does it come from sources of water and water cycle availability and forms of water the water cycle

  1. humidity.

  2. rain.

  3. vapour.

  4. None of the above.

Show answer
Correct Option: B
Explanation:

During water cycle, the water is circulated back from the earth in the form of rain or snow.

Hence, option B is correct.
