Chemical Weathering
chemical
Yes
There are 2 main processes of weathering, mechanical weathering and chemical weathering. In both processes the rocks are broken down. In the mechanical weathering process the rocks are simply made smaller. they are the same composition, just smaller pieces. In the process of chemical weathering the minerals in the rocks undergo a chemical change, they break down. This break down of minerals make them easier to erode. But, erosion is a different question.
Clay minerals are the product of chemical weathering of silicate minerals, such as feldspars. Clays are silicate minerals.
Minerals are usually small colored gems, whereas rocks are usually black, grey or white. Also, minerals have a chemical in which makes our bodies better. Those minerals are used in mineral water. Rocks do not have that chemical.

it provides us with all the rocks and minerals we need for mechanical and chemical purposes
Resorption is the process of dissolving bone and returning its minerals to the bloodstream.
No, not at all. Chemical weathering changes the molecular composition of minerals, but mechanical weathering only changes its shape or outward appearance.
Yes
Intense weathering and erosion will tend to concentrate minerals through chemical or mechanical means.
The most common way is when water that got into cracks freezes and expands, breaking apart the rock. Other simple ways include minerals dissolving in moving water (especially with soluble minerals like calcium carbonate = limestone.)
Plant growth is both a chemical and mechanical process. The roots secrete mild acids that dissolve minerals in rocks, and the plant's roots and stems can increase in size and force rocks apart inside cracks and crevices.

Uranium is extracted by mining as minerals; these minerals are transformed in pure uranium compounds during a long physical/chemical chain of processes: grinding, dissolving, filtration, ion exchange, precipitation, solvent extraction, calcination, reduction, etc.
