    Solution:

    The above statement is true.
    The soil contains minerals, organic matter, air and water. Soil aeration influences the availability of many nutrients. Particularly, soil air is needed by many microorganisms that release plant nutrients into the soil. Organic matter contains humus that has been converted by microorganisms to a resistant state of decomposition. It provides minerals to the soil for the healthy growth of plants and crops. It is the upper layer of the Earth's crust, and plants and animals need to survive and sustain on the Earth. The weathering makes it of rocks, and it also contains rock particles in it.
