Which is the final step of a water cycling driving small turbines before it is fed back into the primary pool?

  1. Evaporation

  2. Fermentation

  3. Sublimation

  4. Vaporisation
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Evaporation is the final step of a water cycling driving small turbines before it is fed back into the primary pool. Water vapours are moving in the pipe at high speed under pressure exposed to turbine; which makes turbine rotate; left water vapour again condenses and go back in liquid state.

Multiple choice biology transport in plant transport of water and minerals conduction of water and minerals absorption of water and minerals in plants

A water-logged soil is physiologically dry because of

  1. Anaerobic conditions

  2. Non movement of water capillaries

  3. Increased viscosity of water

  4. Abundance of salts
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Water-logging indicates to the concentration of soil with water. When the soil is saturated with water over the course of time leads to blockage of air phases and anaerobic condition is succeeded, now the soil may be regarded as waterlogged. In the intense condition (physiologically dry) continued waterlogging leads to anaerobiosis (life sustaining by organism in the absence of oxygen), mostly occurs to mesophytes roots, denitrification and methanogenesis due to reduced atmosphere. 

So, the correct answer is option A.

Multiple choice zoology forests: our lifeline afforestation deforestation and its effect deforestation

Which of the following helps the soil to prevent the flood?

  1. Forest

  2. Animals

  3. Fishes

  4. None of the above
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation
  • Trees help keep soil in place by holding a large amount of soil with there roots.
  • Without trees, rain runs off soil into rivers and streams, raising the water level which leads to floods.
  • Planting trees acts to shield soil from the winds, and the mulch from fallen leaves forms a layer to protect the soil on the "forest" floor.
  • Hence the forest helps the soil to prevent the flood.
  • So, the correct answer is 'Forest'.

Read the give statements and select the correct option. 
Statement 1 : Irrigation without proper drainage of water leads to waterlogging in the soil.
Statement 2 : Waterlogging draws salts to the soil surface, which are deposited as a thing crust on the land surface or start collecting at the roots of the plants.

  1. Both statements 1 and 2 are correct.

  2. Statement 1 is correct but statement 2 is incorrect.

  3. Statement 1 is incorrect but statement 2 is correct.

  4. Both statements 1 and 2 are incorrect.
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Improving drainage from the inundated paddock can decrease the waterlogging period at which the crop roots are subjected to anaerobic conditions. waterlogging draws salt to the surface of the soil. The salt than is deposited as a thin crust on the land surface or starts collecting at the roots of the plants. All the statements are true.

So, the correct option is 'Both statements 1 and 2 are correct'.

Rani had an uneven plot of land in which water was scarce. What system could she adopt for irrigation?

  1. Sprinkler system

  2. Canal irrigation

  3. Fertigation

  4. Hand pump
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation
  • Sprinkler irrigation is a method of applying irrigation water which is similar to natural rainfall. Water is distributed through a system of pipes usually by pumping. It is then sprayed into the air through sprinklers so that it breaks up into small water drops which fall to the ground.
  • This system is used on uneven lands where less water is available.
  • Sprinkler system is suitable for crops such as cereals, pulses, wheat, sugarcane, groundnut, cotton, vegetables, fruits, flowers, spices and condiments and for cultivating paddy crop.
  • Hence Rani should use the sprinkler irrigation system.
  • So, the correct answer is 'Sprinkler system'.

Method of irrigation is

  1. Surface irrigation

  2. Sprinkler irrigation

  3. Drip irrigation

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

Surface irrigation is a method by which water is supplied to the soil surface by gravity. It is one of the commonest method used in agriculture. Sprinkler method is used to supply the water in the form of rain by using pipes through pumping. Watering plants by drip irrigation method is a more economical way of watering plants. In this technique, water is supplied drop by drop near the plant roots through the small opening is called as drippers. By this method, there is no loss of water due to seepage, runoff or evaporation. Thus the correct answer is option D.
