Mineral Properties
The color of a mineral's powder when rubbed against a tile.
What is streak?
Rock that forms from the cooling of magma below the surface or lava at the surface.
What is igneous rock?
The series of processes that slowly changes rocks from one kind to another.
What is the rock cycle?
A repeating pattern of a mineral's particles forms this solid
What is a crystal?
The term used to describe how light is reflected from a mineral's surface.
What is luster?
Rock that forms from heat and pressure deep beneath Earth's surface
What is metamorphic rock?
This step in the rock cycle creates the particles used to form sedimentary rock.
What is erosion?
Molten rock found below Earth's surface.
What is magma?
A property where a mineral splits apart evenly along flat surfaces.
What is cleavage?
Small, solid pieces of material that come from rocks or living things.
What is sediment?
The process where dissolved minerals crystallize and "glue" sediment together
What is cementation?
Igneous rock with large, easy-to-see grains is described as having this texture
What is coarse grained?
This term means a mineral contains no materials that were once part of living things
What is inorganic?
Igneous rock formed from lava that erupted onto Earth's surface.
What is extrusive rock?
In the rock cycle, any rock carried on an ocean plate can return to the mantle and do this.
What is melt (to form magma)?
A characteristic type of "break" for minerals that do NOT split apart evenly.
What is fracture?
Most minerals are these: substances in which two or more elements are chemically combined.
What are compounds?
The group of rocks most likely to contain fossils.
What is sedimentary rock?
To become metamorphic rock, a rock must undergo these two conditions
What are heat and pressure?
Generally, a rock is made up of a mixture of these
What are minerals and other materials?
