Consider the following statements-
(a) Alluvial soil are formed by sediments deposited by rivers.
(b) Black soil is found in the dry and Semi-dry areas of Rajasthan and Gujarat.
(c) Red soil cannnot retain much moisture. 
(d) Laterite soil is found over lava deposits in the Deccan.
Which of the above statements are correct?

  1. (a),(b) and (c)

  2. (a) and (c)

  3. (b) and (d)

  4. None of them

B Correct answer
Explanation
  • Alluvial Soils are formed by the deposition of silt by the rivers. 
  • The black soil is formed in the Deccan region on account of climatic conditions here and the basalt rock which is the parent rock for this soil is also an important factor for the formation of black soil. Black soil is sticky and possesses high moisture retention capacity. 
  • The main reason for laterite soils formation is due to intense leaching. Leaching happens due to high tropical rains and high temperatures. As a result of high rainfall, lime and silica are leached away, and soils rich in iron oxide and aluminum compound are left behind.

In the lower parts of the stratosphere, there is no change in temperature with altitude. This zone is called ________.

  1. Thermosphere

  2. Isothermal Zone

  3. Ozone layer

  4. Ionosphere

B Correct answer
Explanation

In the lower parts of the stratosphere, there is no change in temperature with altitude. This zone is called isothermal zone
An isothermal layer is defined as a vertical column of air having a constant temperature with height. Isothermal layers often occur in the low levels of the troposphere during a differential advection situation.

The part of atmosphere which is consists of variable gasses with unknown composition is called ____________.

  1. Stratosphere

  2. Hetrosphere

  3. Homosphere

  4. None of these

B Correct answer
Explanation

The part of the atmosphere which is consists of variable gasses with unknown composition is called Hetrospere.
The heterosphere is the upper portion of the Earth's atmosphere, in which gases are fractionated according to their molecular weight. It lies above the homosphere, where chemical constituents are well mixed.

The most abundant constituent of dry air in terms of volume is ________.

    1. carbon dioxide

    2. nitrogen

    3. oxygen

    4. none of these
    Reveal answer Fill a bubble to check yourself
    B Correct answer
    Explanation

    Nitrogen is important gas of which about 78% of the atmosphere's volume is made up. Nitrogen serves mainly as a diluent. It is relatively inactive chemically, though many f its compounds are very active. Its main function in the atmosphere is to regulate combustion by diluting oxygen. It also indirectly helps in oxidation of different kinds.

    The most important layer of the atmosphere is ________.

    1. Troposphere

    2. Thermosphere

    3. Mesosphere

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

    Troposphere is considered as the most important layer of atmosphere. It is the lower most layer of the Atmosphere. Its average height is 13 km. The thickness varies from 8 km to 18 km, with maximum at equator and minimum poles. All the atmospheric phenomena such as rains, wind, clouds, etc. take place in this layer. Troposphere contains roughly 80% of the mass of Earth's atmosphere and it composed of composed of nitrogen (78%) and life giving gas oxygen (21%) with small concentrations of other trace gases. Hence, Troposphere is very important for the existence of life on earth as it causes the cloud formation, raining and maintaining the heat balance of the earth.

    The lower layer of the atmosphere is known as __________.

    1. Mesosphere

    2. Ionosphere

    3. Troposphere

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

    Troposphere,

    The troposphere is the lowest layer of the Earth's atmosphere. The air is very well mixed and the temperature decreases with altitude. Air in the troposphere is heated from the ground up. The surface of the Earth absorbs energy and heats up faster than the air does.
