Earth's Layers
The outermost layer of the earth
crust
The three types of rocks
igneous, metamorphic, sedimentary
What are the rock plates that build up the crust called?
tectonic plates
What are the two types of rock dating?
Relative and absolute
What layer of the earth is made from liquid iron and nickel?
Outer Core
This layer has magma in it
mantle
this rock type is made from intense heat and pressure
metamorphic
What tectonic plate movement is plates moving away from each other?
Divergent
What type of rock dating dates the rocks by the other rocks around it?
relative dating
What is the term for rocks being carried away after being broken down?
This layer is made of solid iron and nickle
inner core
This rock type is made from solidified magma
Igneous rock
What tectonic plate movement moves away from other plates?
Divergent
What type of rock dating ages the rocks by the amount of decay it has?
Absolute dating (called radioactive decay)
What is the term for the location where rock sediments land after moving?
Deposition
This layer has a magnetic force
outer core
The rock type is made from a collection of sediments that have cemented together
sedimentary rock
What tectonic plate movement slides against each other?
transform
What is the method for aging a rock that measures the amount of radioactive substances in the rock?
Radioactive dating
Are intrusions older or younger then rocks they cut through?
This sub-layer has the tectonic plates and is located in the crust and upper mantle
lithosphere
The breaking down of rocks
weathering
What tectonic plate movement creates mountains over time?
Convergent
What is the law that states that the oldest rocks are on the bottom, and the youngest rocks are on the top?
Law of superposition
Is a rock inclusion older or younger then the rocks it is found in?
Older!
