A team of engineers wants to study hard, solid rock under the surface of Earth. The team is considering drilling down in South Korea (1) and in the Yellow Sea (2). Where will the team find hard, solid rock?

there all right good

explanation:

practical process described pest part of scientific investigation.

because practical knowledge is powerful then therotical knowledge.

answer is: naturally occurring solid, inorganic compound or element is mineral.

minerals usually have crystalline form, that means than crystal constituents (atoms, molecules or ions) are arranged in a highly ordered microscopic structure, forming a crystal lattice that extends in all directions.

for example magnetite is a mineral of iron oxide (fe₂o₃).

calcite is a carbonate mineral and the most stable polymorph of calcium carbonate (caco₃).

dolomite is an   carbonate mineral composed of calcium magnesium carbonate (camg(co₃)₂).
