- 14. Multiple Choice
Two minerals are the same hardness, color, and
luster. What other test can students do to help
identify the minerals?
They can rub the minerals on something hard to
see what color streak they leave.
They can shine light on the minerals to see how
much light they reflect.
They can rub the minerals together to see if one
will scratch the other.
They can drop the minerals to see how quickly
they break.

Limestone is a type of rock that can form in two
ways. It can either form from the accumulation of
shell and skeletal debris of ocean organisms, or it
can form when calcium compounds precipitate
out of ocean water and become cemented
together. Under which classification does
limestone belong?
igneous rock
silica rock
metamorphic rock
sedimentary rock
- 16. Multiple Choice
