Fossil evidence
the fossil matching up between contients
Rock Correlation
found all around the cost matching up
Glacial Evidence
because it fits like a puzzle
Plate
crust and upper mantel
Divergent
Plates move away from each other
Transform
Plates slide past each other
Convergent
coming together
Subduction
one plate “subducts” under the other because of density
Continetal crust
coming towards
Earthquake
release of energy due to movement of earth tectonic plates
Focus
point down in earth where earthquakes happen
Epicenter
point on earth surface directly above the focus
Modified Mercalli scale
based off damage earthquakes causes not based off energy released
Richter scale
based off energy released higher the number larger the release of energy
Seismograph
the instrument that records earthquakes waves
Seismogram
actual paper recording of seismic waves. Tells a lot of information on earthquakes
“P” waves
fastest waves travel through all materials compression movement
“S” waves
arrive after P waves only travel through solids transvers
