26. formulating hypotheses a mineral forms
deep beneath the surface. it reaches earth's
surface during mountain building. describe two
things that might happen to this mineral at the
surface.

The minerals that are formed deep beneath the earth surface comes to the earth's surface by following two ways.

Explanation:

It can come out in the form of volcano or lava and once cooled will form an igneous rock. It can also come out due to the movement of tectonic plates and can for metamorphic rock.

Basalt and granite are the commonly found minerals. The mineral crystals mostly form rocks. The lava on the surface sometimes gets cool so quickly that it fails to crystallise some minerals.

when atoms of different types of elements join together, they make molecules called compounds. water consists of compound molecules made up of 2 hydrogen atoms and 1 oxygen atom. this is why it's called h2o. water will always have 2 times the number of hydrogen atoms as oxygen atoms.
