How do you know if a rock is valuable?
The harder a mineral is, the more likely it is to be valuable. If you can scratch the mineral with your fingernail, it has a hardness of 2.5 Mohs, which is very soft. If you can scratch it with a penny, its hardness is 3 Mohs, and if it takes a piece of glass to scratch it, the hardness is 5.5 Mohs.

What type of rocks are found outside?
When they are formed inside of the earth, they are called intrusive, or plutonic, igneous rocks. If they are formed outside or on top of Earth’s crust, they are called extrusive, or volcanic, igneous rocks. Granite and diorite are examples of common intrusive rocks.
What does it mean when a magnet sticks to a rock?
A magnet will stick to the meteorite if it contains much metal. Some meteorites, such as stony meteorites, contain only a small amount of metal, but will attract a magnet hanging on a string. Metal detectors can alert you to whether a rock contains metal, but not all metal is magnetic.

What are 5 ways to test a rock?

How do you tell if a rock is hard?
In simple terms, hard rock scratches glass and steel, usually signifying the minerals quartz or feldspar, which has a Mohs hardness of 6 or higher. Soft rock does not scratch steel but will scratch fingernails (Mohs scale of 3 to 5.5), while very soft rock won’t even scratch fingernails (Mohs scale of 1 to 2).

Obsidian has a glassy lustre and is slightly harder than window glass.
