Rubbing a mineral across a white, unglazed tile produces this.
What is a streak?
Rocks are made of these.
What are minerals.
Most sedimentary rocks are formed here.
What are oceans.
When shale is exposed to heat and pressure without melting this rock is formed.
What is slate?
This plutonic rock is course grained and felsic.
What is granite?
When a mineral breaks along a flat surface it shows this property.
What is cleavage?
This is how rocks are classified.
What is origin (how they were formed)?
This bioclastic sedimentary rock is made from plant remains.
What is coal?
This metamorphic rock shows bands of different minerals.
What is gneiss?
This rock cooled so fast it turned to glass.
What is obsidian or basalt glass?
This scale is based upon the relative hardness of common minerals and objects.
What is Mohs' scale of hardness?
These are rocks formed from the solidification of magma.
What are igneous rocks?
This sedimentary rock will bubble with acid.
What is limestone?
This metamorphic rock will bubble with acid.
What is marble?
This rock has the same mineral composition as granite but contains vesicular gas pockets.
What is vesicular rhyolite or pumice?
Mineral properties are determined by the arrangement of these.
What are atoms?
These rocks are formed through compaction and cementation.
What are sedimentary rocks?
This clastic sedimentary rock is made from the finest sediment.
What is shale?
Exposing sandstone to extreme heat and pressure without melting will make this rock.
What is quartzite?
This volcanic rock contains pyroxene and has fine grained texture.
What is basalt?
This mineral is harder than glass, can be red or green, and shows fracture.
What is garnet?
Metamorphic rocks can be naturally made from these types of rock (name all major types).
What are sedimentary, igneous, or Metamorphic rocks?
This sedimentary rock contains pebbles and other rocks.
What is conglomerate?
This rock is only made through contact metamorphism.
What are hornfels?
This rock cooled deep within the earth and contains plagioclase feldspar and pyroxene.
What is gabbro?
