What is soil made up of?
Soil is made up of tiny pieces of rocks that have broken down over time, along with old leaves, roots, stems, and living and dead animals like insects.
It contains both visible materials like sand particles, small stones, and organic matter, as well as microscopic organisms too small to see.
The top layer of soil also contains air spaces and water, creating a habitat for many creatures like ants, termites, beetles, grasshoppers, earthworms, and millipedes.
Explanation
The chapter clearly states that 'Soil is the topmost layer of the Earth's surface. Soil is made from rocks that have broken up into tiny pieces, as well as old leaves, roots, stems and living and dead animals like insects.'
