Which of the following methods of cultivation causes salinisation of soil?

  1. Transplantation

  2. Crop rotation

  3. Excessive irrigation

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

Excessive irrigation increases the amount of salt on the surface of soil due to evaporation. The accumulation of salts damages the soil fertility, except rice; almost all crops receive as ever set back in their growth when excess water stagnates.

Multiple choice biology reproduction in higher plants growth and development in plants sexual reproduction in plants post fertilization - plants

Read the statements given below and determine the correct statements.
(i) Seeds require moisture for germination.
(ii) Plants can absorb nutrients mostly in dissolved form.
(iii) Irrigation protects crops from both frost and hot air currents.
(iv) Irrigation improves soil texture.
Choose the combination of statements which indicate the need to irrigate crops.

  1. (i) and (ii)

  2. (i), (ii), (iii)

  3. (i), (ii), (iii), (iv)

  4. (i) and (iii)
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

A dormant seed contains only 10-15% of water and is essentially dehydrated. The seed has to absorb water in order to become active. Plants grow by absorbing nutrients from the soil and all the nutrients have to be in the dissolved form.
Irrigation does not always improve soil texture. Irrigation does not protect the crops from frost. Irrigation is the artificial application of water to the land or soil. It is used to assist in the growing of agricultural crops, maintenance of landscapes, and revegetation of disturbed soils in dry areas and during periods of inadequate rainfall.

Precipitation and groundwater are sources of _________.

  1. Fresh water

  2. Pure water

  3. Rain water

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

  • Globally water occupies a major portion. Water constitutes 96.5 % on the earth and rest is land. Of the total water content fresh water contributes a very little portion of 2.5%. Fresh water sources include:
  • Groundwater - water found in shallow aquifers beneath the earth's surface. This water is generally found at depths up to around 2,000 feet deep.
  • Precipitation: It is nothing but the rain water which is an important source of fresh water. In fact it is the purest natural source of fresh water.

  2. 30 Cm above the ground level

  3. The run-off from buildings or trees should not enter the funnel

  4. All the above conditions are needed
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation
  • A rain gauge is a little cylindrical container that collects rainwater falling into it to measure the rainfall during a particular period.
  • Certain conditions are needed to be fulfilled for accurate measurement of rainfall viz water should not enter into the rain gauge from any source other than direct rainfall and the rain gauge instrument has to be kept at a certain height.

Multiple choice geography water on earth the atmosphere elements of weather and climate :humidity hydrologic cycle elements of weather and climate : temperature

Water in atmosphere is recharged through which one of the following process? 

  1. Carbon cycle

  2. Nitrogen cycle

  3. Hydrological cycle

  4. Hydrogen cycle
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

Water in atmosphere is recharged through hydrological cycle. In hydrological cycle, water is evaporated from the surface of the ocean. As moist air is lifted, it cools and clouds are formed by condensation of water vapors. These clouds transfer this water to ground through rains. Groundwater either seeps its way to into the oceans, rivers, and streams, or is released back into the atmosphere through transpiration. This cycle keeps repeating itself to keep balance of water.
