Igneous
"Ignis" is the Latin word for what?
Fire
Pieces of solid material that have been deposited on the Earth surface
Sediments
This feature of metamorphic rocks ranges from fine to coarse
Grain Size
Cementing sediment together
Cementation
How a mineral feels to the touch
Texture
Magma and lava
Sediment layer with particles of similar in size, density or shape
Sorted
This feature of metamorphic rocks is characterized by a wavy alignment of layers of minerals or banding of minerals
Foliated rocks
A form of metamorphism that comes from vertical pressure or from the compressive forces associated with mountain building and also increases with depth
Pressure
The tendency of a mineral to break apart relatively easily and evenly
Cleavage
Cooling rate & crystal size
What sediments are mixed in size, density or shape
Unsorted sediments
This type of metamorphism occurs when heat and pressure affect large regions of the Earth's surface
Regional Metamorphism
Overlying water and sediments provides weight and pressure that compresses or compacts sediments, reducing pore space and volume
Compaction
The color when a mineral is broken apart and powdered
Streak
Magma is hot fluid or semifluid beneath Earth's crust, while lava is found where?
on Earths surface
Deposition of sediments in layers
Stratification
FILL IN THE BLANKS: Metamorphic rocks form when ___ and/or _____ alter the mineralogy or chemical composition of existing without melting them
Heat & Pressure
The removal and movement of materials from one location to another
Erosion
The way a mineral reflects the light from its surface
Luster
What are the two main types of igneous rocks?
Intrusive and extrusive
The process of layers of loose sediment stacking on top of each other to create pressure and solidify sediment into solid rock
Burial
This type of metamorphism occurs when molten magma intrusions come in contact with solid rock causing the solid rock to change
Contact Metamorphism
The physical or chemical process that breaks rocks into smaller pieces
Weathering
Minerals of the same size with different weights, often measured using specific gravity
Density
