Hint: We know that due to heavy winds, climate change or water flow, big rocks get broken down into small rock particles and this process is known as weathering of rock. After the weathering process, the rocks get mixed with different components like organic matter (humus), minerals, air and water. So, we will see what is formed when rock particles and humus combine and form a mixture.
Complete answer:
We know that rocks are generally big in size. Due to the action of heavy winds, climate change, temperature change or water flow, these rocks get broken down into small rock particles. This process of breaking down of rock is known as weathering of rocks.
So, after the weathering process, the rocks get mixed with different components like organic matter (humus), minerals, air and water. Humus is an organic substance which is formed by decomposition of plant material and leaves by the microorganisms present in the soil.
Hence, the mixture of rock particles and humus is called soil.
Therefore, the correct answer is soil.
Note:
Humus as we defined above is the organic substance which is formed when the plant material and leaves are decomposed by the microorganisms present in the soil. Humus is the main constituent of the soil and it makes the soil fertile. Hence, humus acts as a fertilizer and important for the fertility of soil. Soil also contains minerals, water and air.
