When two plates rub against each other
Transform
When two continental plates are converging
Mountains
Wegner's theory
Continental Drift
Energy is transferred by direct contact
Conduction
When to plates collide -> <-
Convergent
When two plates are transforming
earthquake
Hess's theory
Seafloor spreading
Touching a hot pot and getting burned
Conduction
When two plates move away from each other <- ->
Divergent
When an oceanic plate and a contential plate converge
Volcanoes
The boat that proved both of their theories
Glomar Challenger
Spread out from a certain point from waves
radiation
This happens during transform
Earthquakes
When two oceanic plates are diverging
Mid Ocean Ridges
Why did Wegner's theory get denied?
He didn't know how, when, or why the plates moved.
What makes a hot air balloon go up?
Convection currents
Wegner's theory on how the plates move
continental drift
When two oceanic plates converge
islands and volcanoes can form
When did Hess discover seafloor spreading?
1946
movement in a gas or liquid in which the warmer parts move up and the cooler parts move down the currents
Convection
