Answer:
- Poor soil is either too heavy (clay soil which holds nutrients and water but doesn't drain well, and can be hard for the plant roots to push through), or too light (sandy soil which drains very well, but means water and nutrients can just wash away). that is why soil is not a mineral.
- Minerals are substances that are formed naturally in the Earth. They are the building blocks of rocks. Minerals are usually solid, inorganic, have a crystal structure, and form naturally by geological processes. ... A mineral can be made of single chemical element or more usually a compound.
- Minerals are important for your body to stay healthy. Your body uses minerals for many different jobs, including keeping your bones, muscles, heart, and brain working properly. Minerals are also important for making enzymes and hormones. There are two kinds of minerals: macrominerals and trace minerals.
