Misc.
100
The wearing away or slow breaking apart of rocks into smaller pieces.
What is weathering
100
Breaks in rocks
What is faults
100
The outer layer of earth. 6-14 miles thick (thinnest layer). the layer we live on.
What is crust
100
This is a large landform that forms peaks. The peaks stretch high above surrounding land.
What is mountain range
100
Magma that flows onto Earths surface.
What is lava
200
The movement of sediment from one placeto another.
What is erosion
200
The point inside the Earth where the Earthquake began.
What is focus
200
The layer of earth between the crust and core. 1800 miles thick. Made of lots of iron and magnesium.
What is mantle
200
A large area thin crust on earth covered by seawater.
What is ocean basin
200
Forms at a convergent boundary. Continental crust forms upward to create a landform.
What is Mountain Range
300
The dropping of sediment by wind, water, or gravity.
What is deposition
300
the point on earths surface right above where the earthquake started.
What is epicenter
300
The center part of the Earth. Mostly made of iron.
What is Core
300
Deepest parts of the ocean A long narrow depression on the sea floor.
What is deep ocean trench
300
Forms at a divergent plate boundary. Two ocean plates move away from each other. This causes the sea floor to spread.
What is ocean basin
400
Two oceanic crusts move apart and magma come up to the mantle forming a new crust.
What is seafloor spreading
400
tools located near the surface of the earth that records seismic waves.
What is seismograph
400
Tis core is liquid. 1375 miles.
What is outer core
400
A rupture in the crust of the Earth that allows magma(lava) gases and ash to escape from inside earth.
What is Volcano
400
Forms at a convergent plate boundary. This is the deepest zone where an oceanic plate sub ducts under a continental plate.
What is deep ocean trench
500
The denser plate sink below
What is subduction
500
a tracing of the earthquake motion made by the seismogram.
What is seismogram
500
this core is solid. 1700 miles.
What is inner core
500
When rocs break along a fault causing energy to release.
What is Earthquake.
500
Forms at a convergent plate boundary. the sub ducted plate melts and rises up through rupture in the crust
What is volcano
