Boundaries
What are convergent boundaries?
denser plate slides underneath lighter plate
What is a subduction zone?
A supercontinent
What is Pangea?
A way to measure plate movement
What is a seismograph
What is above plate boundaries?
Boundary type with a high level of earthquakes
What is a transform boundary
seafloor spreading, continental drift, fossil record
What is evidence of plate tectonic theory
Area of sea floor spreading showing the American and Eurasian plate are moving apart
What is the mid atlantic ridge?
A convergent boundary between plates of different densities (ocean-continental)
Two plates pull away from each other forming a rift/ridge
What is a divergent boundary?
Plates moving apart from each other
What is a convergent boundary?
Came up with the Theory of Plate Tectonics and Pangea
Who is Alfred Wegner?
A volcano is associated with this area
What is a hot spot?
hot magma rising, cooling, and sinking
What are convection currents?
Plates moving alongside and opposite each other
What is a transform boundary
Earth's solid outer crust
What is the lithosphere?
Plates moving towards each other
Convergent boundary
Oceanic and continental plates move apart, come together, and interact with plates all over the planet
What is tectonic plate theory?
Type of boundary where you are likely to have volcanos form
What is a divergent or convergent boundary
Physical layer of the earth comprising tectonic plates
What is the crust?
