  • Question 1
    1 / -0
    Identify the forms of precipitation.
    Solution
    Precipitation is any liquid or frozen water that forms in the atmosphere and falls back to the Earth. It comes in many forms, like rain, sleet, and snow.
    Thus, the option is - 'All of the above'.
  • Question 2
    1 / -0
    Which of the following statement is true?
    Solution
    Air is a mixture which is composed of several gases like oxygen 21%, nitrogen 78%, carbon dioxide 0.03% and water vapors. The air molecules are held by strong intermolecular forces. When air is heated up, the air molecules absorb the heat and the intermolecular forces between the air molecules become weak and its kinetic energy increases. The air molecules move apart and become less dense and thus they expand on heating.
    So, the correct answer is option A.
  • Question 3
    1 / -0
    Choose the correct answers from the alternative given.
    Soil-conservation is a process in which :-
    Solution
    Soil conservation is the prevention of loss of the top most layer of the soil from erosion or prevention of reduced fertility caused by over usage, acidification, salinization or other chemical soil contamination.
    Thus, the correct option is D.

  • Question 4
    1 / -0
    Choose the correct answer from the given alternatives.
    The largest reservoir of nitrogen on the earth is:
    Solution
    Nearly 78% of the Earth's atmosphere is nitrogen. Apart from this, nitrogen is an indispensable part of many biomolecules like proteins, nucleic acids, vitamins, etc. It is also found in small quantities in biologically important compounds like ammonia and urea. However, air which contains 78% of nitrogen is the largest reservoir of nitrogen.
    So, the correct answer is 'C'.
  • Question 5
    1 / -0
    Nitrogen and hydrogen combine to form ammonia under high tempreture and pressure conditions. This is an example of 
    Solution
    During lightning, the high temperatures and pressures created in the air convert nitrogen into oxides of nitrogen. These oxides dissolve in water to give nitric and nitrous acids and fall on land along with rain. These are then utilised by various life- forms.
    The correct option is B.
  • Question 6
    1 / -0
    Which of the following process is responsible for the smoke-like vapour which comes out of the mouth in winter?
    Solution
    • When you exhale when it's cold outside, the water vapour in your breath condenses into lots of tiny droplets of liquid water and ice (solid water) that you can see in the air as a cloud, similar to fog which appears smoke like. This process is called condensation.
    • Hence Condensation process is responsible for the smoke-like vapour which comes out of the mouth in winter.
    • So, the correct answer is 'Condensation'.
  • Question 7
    1 / -0
    The water vapour that enters the air to form clouds in the sky is obtained by which of the following process?
    Solution
    • Evaporation is a type of vaporization that occurs on the surface of a liquid as it changes into the gas phase.
    • By the process of evaporation, the water vapour enters into the air to form clouds in the sky. 
    • The water vapour in the air condenses to form tiny water droplets which are the basis of clouds.
    • Hence the process by which water vapour enters into the air to form clouds in the sky is Evaporation.
    • So, the correct answer is option B.
  • Question 8
    1 / -0
    One example of a nutrient in its reduced form is
  • Question 9
    1 / -0
    Which process results in the decrease of nitrogen content in the soil?
    Solution

    A. Ammonification – The formation of ammonia from the dead bodies of plants and animals by means of decay or decomposition is called Ammonification. Employing this process, nitrogen content in the soil increases.

    B. Biological nitrogen fixation – Conversion of atmospheric nitrogen into nitrogenous compounds utilizing microorganisms is called Biological nitrogen fixation. With the help of this process, nitrogen content in the soil increases.

    C.Denitrification – Conversion of nitrates or nitrites into atmospheric or gaseous nitrogen is called Denitrification. Employing this process, nitrogen content in the soil decreases.

    D. Nitrification – formation of nitrates from ammonia is called Nitrification. Through this process, nitrogen content in the soil increases.

    So, the correct option is ‘Denitrification’.
  • Question 10
    1 / -0
    Water cycle refers to
    Solution
    Water cycle refers to the constant movement of water from the ocean to land and back to the ocean again. It happens when water changes from water vapour in the atmosphere to liquid water through condensation and precipitation and falls on land and via channels and river flows back to the ocean and then back to water vapour through evaporation, transpiration, and respiration. 
    so, the correct option is B. ( Constant movement of water from the ocean to land and back to the ocean again )
