· Minerals are naturally occurring elements found in the earth. Rock formations consist of mineral salts. Rock and stone gradually break down, by erosion, into tiny fragments called sediment. This takes millions of years. The dust and sand left over accumulate and form soil. It teems with mineral salts, which plants absorb.

· Types of Minerals There are many different types of minerals, but they are often divided into two groups: silicates and non-silicates. Silicates are minerals that contain silicon and oxygen. Over 90% of the Earth's crust is made up of silicates. The rest of the minerals are lumped into a group called non-silicates.
