The Rock Cycle
100
Two plates collide
What is a converent boundary?
100
This is the molten material that comes out of a volcano
What is lava
100
This is the hotest layer of them all and is made up mosly of iron and nickel
What is the core?
100
When there is a "snap" ( release of energy)of two plates, this occurs
What is an earthquake
100
This type f rock is formed from compression and cementation and fossils are usualy found here
What is a sedimentary rock?
200
Two plates are sliding together like scissors
What is shearing?
200
This structure is in a form of a mountain and contains a vent for magma to exit out of
What is a volcano?
200
This layer contains convection currents and because of the rising pressure, the density will increase with the depth
What is the asthenosphere?
200
This is a result of an earthquake that sends large waves bulging outward
What is a tsunami?
200
This rock is chemically changed when it comes in contact with blazing temperatures
What is a metamorphic rock?
300
Two plates divide
What is a divergent boundary?
300
This is an opening where the magma comes out
What is a vent?
300
This layer is the least dense
What is the lithosphere?
300
This is exactly were the "snap" occured
What is the focus?
300
This rock is composed of many visible minerals and is formed when lava cools
What is an igneous rock
400
On top of the upper part of the mantle
Where are plates found?
400
This is an area where the temperature is very pipping hot and usually is where a volcano is
What is a hot spot?
400
This layer is the thinnest when under the ocean but the thickest when it is under continents
What is the crust?
400
This is the only type of boundary that produces an earthquake
What is a transform boundary
400
This forms when rocks melt from heat and pressure and is found inside of volcano chambers
What is magma
500
All continents used to be connected together at one time
What is Pangeauas?
500
This is located around the Pacific Rim
What is the Ring of Fire?
500
These two substances are found in the mantle
What is iron and magnesium?
500
This is also known as a longitudinal wave
What is a p wave?
500
These shell peices are what makes up sedimenary rocks
What are sediments?
