How is soil made?

Answer 1

Soil is formed by the breaking of rocks. Bigger rocks break into small rocks and form soil. For one thing it's not just made of dirt. Dirt is made of materials that plants avoid growing in. Soil, on the other hand is made up of a mixture of decayed organic material, living organisms, and minerals. The organic materials comes from dead plants like banana peels and last year's leaves.

Soil is made up of many layers. This is due to the fact that plants grow on top of the soil and rocks are found underground. The type of soil that forms in a region will depend upon the climate, the bedrock underground, or the plants growing there. Although all soils are made of these basic ingredients, there are many variations. In forests for example, the soil may be deep, rich, and may have a dark brown color. In sandy areas the soil will be dry with a dusty gray color. In tropical regions the soil is often very deep and bright red.

Answer 2

Soil is formed over thousands of years through the weathering of rocks and minerals, the decomposition of organic matter, and the activity of soil organisms. Factors like climate, topography, vegetation, and time all play a role in the formation of soil.

Answer 3

erosion of rocks
Soil is produced by the breaking up of rocks and materials that plants avoid growing in.

Answer 4

by the breakdown of organic matter (anything that once 'lived' over thousands of years)...rinse and repeat.
