Continental Drift followed by Seafloor Spreading

Which theory came first?

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
Land Formations that occur when oceanic crust subducts under continental crust.
What are volcanoes and "volcanic" mountain ranges
200
The three mechanisms that cause the movement of Earth's tectonic plates.
What are mantle convection, slab pull, and ridge push.
200

After using sonar on the ocean floor they discovered mid-ocean ridges growing.

Who was Harry Hess?

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
Formation that occurs at a divergent boundary in the Earth's oceans.
What is a mid ocean ridge and the formation of oceanic crust
300
The Compositional layer of the Earth where convection occurs.
What is the Mantle?
300

Being a meteorologist and not having enough evidence.

What were reasons that people did not support or believe Wegner?

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 motion and process that happens at a divergent boundary.
What happens when two tectonic plates move away from each other forming a rift valley or mid ocean ridge.
400
The type of boundary where ridge push occurs.
What is a divergent boundary?
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
The name of the 8 major tectonic plates.
What are the Pacific, North American, South American, African, Antarctic, Eurasian, Indo-Australian, and Nazca plates?
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?
600

Plate boundaries are where most volcanoes and earthquakes are located.

What is a piece of evidence for Plate Tectonic Theory?

600

The childhood toy that is often used to describe the action of the layer of Earth driving plate motion.

What is silly putty?

600

Two of the Americas landforms found inland and due to subduction zones.

What are the Andes Mountains and the Cascades?
600

This is ultimately responsible for the shifting plates on the planet.

What is the heat from Earth's core?

600

No rocks older than 180 million years old and magnetic reversals.

What are two pieces of evidence for seafloor spreading?

700

As "connectors" for diverging seafloor making making mid-ocean ridges look like zippers.

Where are most of the transform boundaries located?

700

Yosemite National Park and the Hawaiian Islands.

Where are two hot spots in the United States?

700

The plates responsible for volcanic activity and a potential tsunami for Washington.

What are the Juan de Fuca and the North American Plates?

700

Two features occurring in the ocean due to old ocean floor being recycled.

What are island arcs and deep ocean trenches?

700

200 million years ago this what Pangaea turned into.
