This characteristic describes how the faces of a mineral break.
What is a mineral's cleavage?
500
This igneous rock is more dense than granite and makes up the oceanic crust.
What is basalt?

This step in the formation of sedimentary rocks occurs when sediment settles out of water or wind.
What is deposition?
500
This metamorphic rock was once the igneous rock granite.
What is gneiss?
500
This is the number of years it takes for a rock to make it all the way through the rock cycle.
