Term

 

rocks

Definition

Any naturally formed solid that is part of Earth or any other celestial body

 

Usually composed of one or more minerals

Term

 

igneous

Definition
  • intrusive or extrusive rock
  • formed from cooling and crystallization of magma or lava

 

Term

 

metamorphic

Definition

 

a rock that formes from changes in preciously existing rocks due to heat, pressure, and or chemical fluids

Term

 

sedimentary

Definition

 

rock that forms directly from sidiments deposited near Earth's surface by the process of cedimentation, precipitation of mineraly, loss of water, and compaction

Term

 

fossil fuels

Definition

 

the organic fuels found with in Earth's crust

Term

 

crystal structure

Definition
the pattern or arangement of atoms that characterizies each mineral; also called atomic structure
Term

 

cleavage

Definition

 

the tedency of a mineral to break along zones of weakness and form smooth to semi smooth parallel surfaces

Term

 

fracture

Definition

 

a way in which a mineral breaks producing uneaven breaking surface

Term

 

hardness

Definition

the resistance a mineral offers to being scratched or dented

 

comparrison to Moh's hardness scale

Term

 

streak

Definition
the color of the powder of a mineral which is usually more consistant than normal mineral color
Term

 

luster

Definition
the way a mineral looks or shines in reflecting light
Term

 

crystal shape

Definition

 

the outward 3-D shape or geometric shape of a mineral speciment that reflects the internal atomic structure

 

also called crystal form

Term

 

crystalization

Definition
a type of solidification in which molten rock (magma) cools to form igneous rocks composed of mineral crystals
Term

 

solification

Definition
the process by which a liquid changes to a solid
Term

 

magma

Definition

 

liquid rock material beneath Earth's solid surface

Term

 

inferred

Definition

 

an interpretation of an observation

Term

 

rock cycle

Definition
continues dynamic set of process by which rocks are changed into other types of rock
Term

 

contact metamorphism

Definition
local effect that occurs when molten rock meets solid rock
Term

 

sediments

Definition
small pieces of rock that are moved and deposited by water, wind, glaciers, and gravity
Term

 

compacted

Definition
the reduction in volume of sediments in the formation of sedimentary rocks
Term

 

cemented

Definition
the process by which solid sediments or clasts are "glued" together by precipitated minerals, forming a sedimentary rock
Term

 

chemical precipitation

Definition

 

a type of sediment deposition in which dissolved minerals come out of solution to form solids

Term

 

natural resources

Definition

 

resources provided by Earth
