Plate tectonics

Midocean ridge is an example of this type of fault?

Transform Fault

More dense crust is pushed under less dense crust.

Subduction

Topmost part of the Earth

Lithosphere

Plate boundaries that come together.

Convergent boundaries

Movement of air within the atmosphere due to density.

Convection Currents

The Ring of Fire is around the boundary of this plate?

Pacific Plate

The theory that links continental drift and ocean-floor spreading together.

Plate Tectonics

Supporting evidence for ocean-floor spreading.

Magnetic striping

Rock aging

Cores from deep-sea drilling

Plate boundary where one plate slides past one another plate.

Strike-slip boundary

What is the V-shaped valley?

Trenches

World’s largest mountain chain is located here

Midocean Ridges

Alfred Wegener’s theory.

Theory of Continental Drift

Plate boundaries that move apart.

Divergent boundaries

Used to map midocean ridges.

Sonar

Means all of Earth.

Pangaea

Provides the framework for understanding landforms.

Theory of Plate Tectonics

When two continental plates collide with the same density, ______ plates

is subducted.

Neither

Went against many geological basic principles.

Theory of Continental Drift

Rocks deposited by ______ showed evidence of continental drift.

Glaciers

________ records showed evidence that Pangaea existed.

Fossil

Name the Lithospheric plates.

North American

South American

Eurasian

African

Indo-Australian

Antarctic
