Earthquakes/Seismic Waves
The place that earthquakes occur
Edge of tectonic plates and faults in the crust
The type of pattern of a magnetic field reversal
Random
The plates that move away from eachother
Divergent boundary
The largest layer of the earth
Mantle
The super continent that existed before the continents we have today
Pangea
The wave that travels in a straight line and can pass through all matter
P-waves
The way history show magnetic reversal on the sea floor
Symmetrical on the sides of the mid-ocean ridge
The plates that move towards each other
Convergent boundary
The least dense layer
Evidence to why Pangaea is real based on continent shape
The wave that travels in a squiggly line and can not pass through liquids
S-waves
The last time earth's magnetic field was reversed
1 million years ago
The plates that slide past eachother
Transform Boundary
The hottest layer inside of the earth
Inner core
The reason Pangaea split apart
Plate movement
The place above Earth's surface where an earthquake starts
The epicenter
The way a normal magnetic field is attracted
North
Plate movement that doesn't construct or destruct
Transform Boundary
Radioactive decay
Resources found that prove Pangaea existed
Rocks, glaciers, and fossils
The point inside Earth where an earthquake begins
The focus
The way a reversed magnetic field is attracted
South
Effect of a transform boundary
Earthquakes
The state of matter of the inner core
Solid
The reason Pangaea is important
It allowed us to develop the theory for continental drift
