What is the difference between a mineral and a rock?
A mineral is an inorganic solid material found in nature and rocks are made of two or more minerals.
A huge glob of magma rises from deep in the Earth, but a layer of crust keeps it from reaching the surface. Predict what will happen to this gob of magma. Remember that different types of rocks are formed in different ways. And each type of rock is on a continuing journey throughout the rock cycle.

You are given a sample of a mineral. How might you go about finding out what kind of mineral it is?
You could test the cleavage, fracture, color, streak, luster, and hardness. You could also use specific gravity. You could see if it fizzes in acid, attracts a magnet, has double refraction, or you could taste it.
