100
Earth's thickest layer
What is Mantle
100
Large and small slab of rock that are a part of the lithosphere
What is tectonic plate
100
Two plates come together
What is convergent
100
a fracture or break in Earth's lithosphere along which blocks of rock move past each other
What is a fault
100
These are caused by Earthqaukes, there are 3
What is seismic waves
200
A thin layer of cool rock
What is Crust
200
A huge super continent that was around 200 million years ago
What is pangea
200
Two plates move apart
What is diverent boundary
200
A block of rock above the fault plane slides down relative to the other block. Where the blocks are pulling apart
What is Normal Fault
200
an earthquake point underground where rocks first begin to move
What is focus
300
Two types of crust
What is oceanic and continental
300
fossils, climate, geology, and mid ocean ridges are all evidence of what?
What is continental drift
300
plates scrape past each other, crust is neither created nore destroyed
What is transform
300
When two blocks of rock are pushing towards eachtoerh adn the block of rock move above the fault plane
What is reverse fault
300
An instrument that constantly records ground movements
What is a seismograph
400
Earth's crust and very top of the mantle
What is Lithosphere
400
This current causes the plates to move
What is convection
400
Where one plate is pushed underneath another
What is subduction
400
The fault where the two blocks of rock slide past each other
What is strike slip fault
400
What are the three types of volcanoes
What is composite, shield, and cinder cone
500
List all 6 layers of the Earth from inside to outside
What is inner core, outer core, mantle, asthenosphere, lithosphere, and crust
500
Under water mountain ranges that cicle the Earth like a baseball seam
What is mid ocean ridge
500
A process that happens at a convergent boundary, a divergent boundary, and a transform boundary
What is mountains, rift valley, and earth quake
500
