How are Rocks and minerals are held together?

Rocks and minerals are held together primarily through physical and chemical processes. In sedimentary rocks, minerals are often cemented by minerals precipitated from water, binding the sediment particles together. In igneous rocks, minerals crystallize from molten magma, forming a solid structure as they cool. Additionally, metamorphic rocks are created when existing rocks undergo heat and pressure, causing minerals to recrystallize and interlock.
