100
This is what magma becomes when it goes onto Earths surface
What is lava?
100
This is the upper, outermost layer of the earth
What is the lithosphere
100
these are pieces of the lithospere that move around atop the athenosphere
What are tectonic plates
100
This is a break in the earths crust along which blocks of the earth slide away from each other
What is a fault
100
This machine is placed closely to or at earths surface that reads seismic waves
What is a seismograph
200
This is the liquid layer of earths core
What is the outer core
200
This process occurs when new floor of the oceanic lithosphere is created at mid ocean ranges
What is seafloor spreading
200
This is a fault where the hanging wall moves down relative to the climbing wall
What is a normal fault
200
This is the tracing of earthquake motion created by a seismograph
What is a seismogram
300
These are fragments of rock created by explosive volcanic eruptions
What is pyrosclastic material
300
The central, spherical point of the earth is called this
What is the inner core
300
This is the theory that earths lithosphere is divided into plates that move around atop the athenosphere
What is plate tectonics
300
This is a fault in which the fault blocks move horizantally
What is a strike-skip fault
300
This is a circular depression that forms when a magma chamber empties
What is a caldera
400
This is a part of crust above magma
What is a hot spot
400
this is the soft layer of the mantle on which pieces of the lithosphere move
What is the athenosphere
400
This is the boundary between 2 tectonic plates that move away from each other
What is a divergent boundary
400
This is the fastest type of wave. It can move through solids, liquids, and gasses
What is a P wave
400
This is the process by which one rock type turns into another rock type
What is the rock cycle
500
This is a small, steeply sloped volcano that forms moderately explosive eruptions of pyroclastic material
What is a cinder cone volcano
500
This is the middle sphere of the earth, the strong, lower part of the mantle
What is the mesosphere
500
This is the region where an oceanic plate sinks down into the athenosphere
What is a subduction zone
500
This is the second-fastest type of wave. It cannot move through a completely liquid substance
What is an S wave
500
This is the breakdown of rocks into smaller pieces
What is mechanical weathering
