Multiple choice evs sources of water the lithosphere and the hydrosphere first aid safety and first aid

Rain is the ultimate source of water.

  1. True

  2. False
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation
  • The ultimate source of water is the water bodies which are present on earth which includes large oceans, seas, rivers, etc. Rain is only the way of water returning to their sources which they have lost by evaporation.
  • This rain is not an ultimate source of water .the ultimate source are the water bodies present on earth example large oceans, rivers etc
  • So, the correct answer is 'False'.

Choose the correct option. The total water

  1. In the lakes and rivers of the world remains constant.

  2. Under the ground remains constant.

  3. In the seas and oceans of the world remains constant.

  4. Of the world remains constant.
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation
  • The total water of the world remains constant because the water travels through a cycle and the net amount never changes. For example, The water which evaporates from various water bodies like lakes, rivers, ponds, etc form clouds and then they rain down filling up the same water bodies. They also go underground but in the end, they end up in a water body thus completing the water cycle.
  • Hence  The total water of the world remains constant.
  • So, the correct answer is 'Of the world remains constant'.

Which one of the following is not responsible for water shortage ?

  1. Rapid growth of industries.

  2. Increasing population

  3. Heavy rainfall

  4. Mismanagement of water resources
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation
  • Water is one of the most valuable resources on Earth. Rainwater fills reservoirs that supply drinking water, provide a habitat for fish to live, and nourishes the soil with water necessary for vegetation.
  • Hence Heavy rainfall is not responsible for water shortage.
  • So, the correct answer is 'Heavy rainfall'.

Which of the following is most important in water cycle?

  1. Transpiration through leaves

  2. Evaporation from the oceans

  3. Percolation of water into the ground

  4. Absorption of capillary water by plants
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

Evaporation from the oceans is the most important in water cycle, because it comprises of the major part of global water cycle.

Life is sustainable with water only because 

  1. It makes 90% of the protoplasm

  2. Translocation of nutrients inside the body occurs wiith the help of water

  3. Water loss in form of sweating helps to maintain body temperature

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

Protoplasm is the material comprising the living contents of a cell. It consists of 70- 90% water along with the minerals, sugars, amino acids, proteins, enzymes, etc. The translocation of nutrients inside the body occurs viz. blood which also major consists of water. In an environment with excessive heat, water loss in the form of sweating keeps the body cool. Thus, water maintains body temperature. 

So, the correct answer is 'All of the above'.

The water cycle in nature involves which of the following processes sequentially?

  1. Evaporation, precipitation and condensation

  2. Precipitation, condensation and evaporation

  3. Evaporation, condensation and precipitation

  4. Condensation, evaporation and precipitation
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

Water evaporates as water vapour from water bodies like lakes, rivers, seas, etc. It then cools as it moves up and condenses to form clouds of tiny water droplets. When the cloud is saturated with warm droplets, precipitation occurs in the form of rain.

Primary source of water is

  1. Rivers

  2. Ground water

  3. Lakes

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

The primary source of water on the surface of the earth is rain. Rain is mainly formed due to the precipitation of vapours accumulated due to evaporation. Some part of the rainwater is available as ground water which can be used in case of adversity.

So, the correct answer is option D.

The continuous movement of water on surface of the earth is described as

  1. Water movement

  2. Natural flow

  3. Water cycle

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

The water cycle involves the continuous movement of water on, above and below the surface of the Earth. The surface water evaporates by the process of evaporation which condenses into tiny droplets which falls on the earth as rain as a source of the atmospheric cycle. Surface waters and atmospheric cycles are thus overlaps in hydrological cycles. Thus, the correct answer is option C.

All of the following are the properties of water except ____________.

  1. Hydrophilic properties

  2. Hydrophobic properties

  3. Very good solvent

  4. Density as a solid is less than that as a liquid

  5. Strong surface tension
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

Water is a polar molecule, making it hydrophilic and a good solvent. It also exhibits high surface tension. Hydrophobic properties are characteristic of non-polar substances, not water.
