Igneous Rock
This is molten rock found below the earth's surface.
magma
Tiny pieces of rock, sand, shells, etc. are called what
sediment
Metamorphic rocks are formed due to _______ and _______.
heat and pressure
When sediments undergo compacting and cementation processes, they become which type of rock.
sedimentary rocks
Give an example of a rock
granite, sandstone, marble, conglomerate, coal, obsidian, etc.
Igneous rocks are formed from cooled__________
magma
Rocks that are made from sediments of preexisting rocks.
clastic rocks
Term associated with a banded appearance.
foliated
Undergoing weathering and erosion, will show which type of rock?
sedimentary
What are rocks composed of?
minerals and mineral-like materials
Igneous rocks are categorized as _________ or _________, depending on where the molten rock cooled.
extrusive and intrusive
True of False: Once a sedimentary rock, always a sedimentary rock.
If false, correct the statement.
False - the rock cycle is continuous
The two types of metamorphism are _____ and _____.
contact and regional
True of False: The rock cycle is continuous.
If false, correct the statement.
True
Difference between magma and lava.
magma when is underground, lava after errupts.
Intrusive rocks can be found
underneath Earth's surface
This type of sedimentary rocks form when dead plants or animals beak down into sediments.
This type of metamorphism results in major changes to Earth's surface.
_________ and ____________ turn sedimentary rocks into metamorphic rocks.
heat and pressure
Two major contributing factors to sediment
weathering and erosion
True or False: Igneous rocks are formed when sediments break apart. If false, correct the statement.
False - igneous rocks form from the cooling and solidification of magma/lava.
Weathering either be _____ or _____. Give one example of each.
Mechanical (due to atmospheric processes such as rain, wind, freeze/thaw).
Chemical, due to chemical reactions between rocks and acid rain, water or different types of rocks.
Nonfoilated rocks from under what conditions?
High heat and pressure - confining pressure
Metamorphic rocks are formed from heat, pressure, and _____.
fluids
Rocks are classified by
how they form
