What type of property test is a mineralogist conducting when she rubs a mineral over a tile, or hard surface?

• Streak Test

• Luster Test

• Appearance Test

• Cracking Test

Metamorphic rock is the result of

• layers of rock being under great pressure and/or heat

• molten rock cooling over time

• pieces of rock and sediment pushing together

• fossils forming over thousands of years

This rock formed when lava cooled very quickly on Earth's surface. What specific type of rock is it?

What is the difference between a rock and a mineral?

• A rock is an inconsistent mixture of minerals, while a mineral is "pure" and made up of a precise combination of chemicals.
