Sedimentary
Tiny pieces of rock, sand, shells, etc is called what?
Sediment
What is the difference between magma and lava
Magma = below Earth's surface
Lava = above Earth's surface
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
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
_______ is a pattern of layers or stripes found in metamorphic rocks
foliation
Undergoing extreme heat and pressure when buried deep underground
Explain how we formed a metamorphic rock in our starburst experiment
Applied our body heat and harder pressure
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
Teacher assessed
What is the term for the belief that when the earth was formed, it was made of molten rock. Over time, layers in the earth were formed through the process of more dense materials sinking to the core and less dense materials separating into layers.
