Plate Tectonic Plates

Front 1

Continental Drift

Back 1

When continents move from place to place slowly.

Hint 1

Front 2

Plate Tectonics

Back 2

The theory that Earth's outer shell is divided into several plates that glide over the mantle, the rocky inner layer above the core.

Hint 2

Front 3

Pangaea

Back 3

A supercontinent that incorporated almost all the landmasses on Earth.

Hint 3

Front 4

Lithospheric Plates

Back 4

Regions of Earth's crust and upper mantle that are fractured into plates that move across a deeper plasticine mantle.

Hint 4

Front 5

Convection Currents

Back 5

The transfer of heat by the mass movement of heated particles into an area of cooler fluid

Hint 5

Front 6

Transform Boundary

Back 6

A type of fault whose relative motion is predominantly horizontal in either sinistral or dextral direction.

Hint 6

Front 7

Seafloor Spreading

Back 7

A process that occurs at mid-ocean ridges, where new oceanic crust is formed through volcanic activity and then gradually moves away from the ridge.

Hint 7

Front 8

Convergent Boundary

Back 8

Also known as a destructive plate boundary (because of subduction), is an actively deforming region where two (or more) tectonic plates or fragments of the lithosphere move toward one another and collide.

Hint 8

Front 9

Subduction Zones

Back 9

Sites of high rates of volcanism, earthquakes, and mountain building.

Hint 9

Front 10

Divergent boundary

Back 10

A linear feature that exists between two tectonic plates that are moving away from each other.
