Continental Drift and Seafloor Spreading
100

The father of Continental Drift Theory

Who is Alfred Wegener

100
The Compositional layers of the Earth.
What is the crust, mantle, and core.
100
The three types of tectonic plate boundaries.
What are convergent, divergent, and transform
100

The layer of the mantle on which the lithosphere "floats" and where most convection occurs.

What is the ashtenosphere.

100

People did not believe Wegner's Theory because...

He was a meteorologist and he couldn't explain HOW they plates moved.

200

The hypothesis that states our continents broke from one large landmass and slowly drifted apart.

What is continental drift?

200
The Physical layers of the Earth.
What is the Lithosphere, Asthenosphere, Mesosphere, Outer core, and Inner core
200

The process that occurs at a divergent boundary between two oceanic plates.

What is sea-floor spreading.

200

The process where one tectonic plate "slides" under another.

What is subduction.

200

The name of the theory that explained the "how" of Wegner's Continental Drift Theory.

What is Plate Tectonics.

300

The name of the super-continent that Earth's continents broke away from.

What is Pangaea

300
The Compositional layer of the Earth that is the thinnest.
What is the crust
300

What would I expect to happen at a transform boundary?

What is earthquakes.

300
The Compositional layer of the Earth where convection occurs.
What is the Mantle?
300

What landforms are created at spots of Seafloor Spreading?

What are mid-ocean ridges.

400
Pieces of the Lithosphere that slide along the Asthenosphere.
What are tectonic plates
400
The two physical layers that form the single Compositional layer of the core.
What are the inner core and outer core
400

The landforms that are created when two continental plates meet at a Convergent Boundary.

What is mountains.

400

The earth's Continental Crust is mostly made of this type of rock.

What is granite.

400

A location where a column of extremely hot mantle rock, called a mantle plume, rises through the Asthenosphere as it is passing through.

What is a hot spot?

500
The five pieces of evidence that supported Alfred Wegners continental drift hypothesis.
What are matching fossils, coastlines, land-forms, rock layers, and past climates.
500
The Physical Layer that includes the rigid upper portion of the mantle and the crust.
What is the Lithosphere
500
Land Formations that occur when oceanic crust subducts under continental crust.
What are volcanoes and "volcanic" mountain ranges
500
The process that forms a convection current.
What happens when hot fluid material rises and cold fluid material sinks?
500
The name for the area around the Pacific plate where the majority of Earth's Volcanoes form.
What is the Ring of Fire?
