Sedimentary
Tiny pieces of rock, sand, shells, etc is called what?
Sediment
What is one example of an igneous rock?
Obsidian, Basalt, Granite, Pumice
What conditions form metamorphic rock
heat and pressure
Rock formed from heating and cooling magma
igneous rock
Which two types of rocks do we typically see layers
Sedimentary and metamorphic
Near what natural feature does sedimentary rocks usually form?
Water
False; sedimentary
True or False: Melting a rock can make it into a metamorphic rock
False
True or false: The rock cycle is continuous
True
A _______ is a naturally occurring, inorganic, solid material with a crystalline structure
Mineral
What can be found in sedimentary rocks that scientist can use to study about the past
Fossils
Igneous rocks are classified as ________ or ________ depending on where the molten rock cooled
intrusive; extrusive
A _________ has an indefinite chemical composition and no defined shape.
Rocks
Undergoing extreme heat and pressure when buried deep underground
Sedimentary
The processes that turn sediments into a sedimentary rock
Compaction and Cementation
_________ igneous rocks have larger crystals. WHY?
Intrusive; due to longer magma cooling
What action can cause existing rock to undergo extreme pressure
tectonic plate movement
Explain how sedimentary rocks are formed
Existing rocks are weathered and eroded.
The sediment is then deposited where it undergoes compaction and cementation
Explain the law of superposition
Older rock layers are at the bottom
Younger rock layers are at the top
What is the difference between weathering, erosion, and deposition
Weathering breaks rock down, erosion carries it away, and deposition drops the sediment off
Describe how igneous rocks form
Cooling and Hardening(crystallization) of lava or magma
How can a metamorphic rock get to Earth's surface
Earthquake, or the melting of the rock that is then erupted from a volcano
One person from your team come to the board to draw the rock cycle

What is Relative Dating?
the method scientists use to determine the approximate age of a structure based on its physical relationship to the surrounding geological structures.
