History
Alfred Wagner
This rock forms from extreme heat and/or pressure
Metamorphic rock
Most of the earthquakes occur
The Ring of Fire
When plates come together it is called a
Convergent boundary
What is the name of supercontinent we studied?
Pangea
Describe how sedimentary rock forms
Sedimentary rock forms through weathering and erosion. After deposition, the sediments are cemented together
The point of the earth's surface directly above the focus is called the
Epicentre
A rift valley happens under what plate boundary
Divergent boundary
What did Marie Tharp, Arthur Holmes, and Harry Hess contribute to science?
Supported plate tectonic theory and mapped ocean floor.
interlocking crystals, dense, strong, and resistant to weathering and erosion.
What is used to measure seismic activity?
Sesiomgraph
Continental-continental convergent boundaries can form what structures
Earthquakes and fold mountains
What were the five identifiers/proof of continental drift
Jigsaw fit, glaciers, geological evidence, tectonic fit, fossil evidence
What is a major characteristic of metamorphic rock
crystallisation
Where is the place that earthquakes start called
Focus
The plates slide past each other is what boundary name
Transform boundary
