Plate Tectonics Terms

Front 1

Continental drift

Back 1

Is the idea that the continents were once apart of a single land mass called Pangaea

Hint 1

Front 2

Plate tectonics

Back 2

Is the idea that the earths crust is made of large pieces, called plates, that have moved over time

Hint 2

Front 3

Pangaea

Back 3

A supercontinent that existed many years ago

Hint 3

Front 4

Lithospheric plates

Back 4

regions of Earths crust and the upper mantle that are fractured into plates that move across a deeper plasticine mantle.

Hint 4

Front 5

Convection currents

Back 5

a current in a fluid that results from convection.

Hint 5

Front 6

Divergent boundary

Back 6

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

Hint 6

Front 7

Seafood spreading

Back 7

is 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

an active deforming region where two or more tectonic plates or fragments of the lithosphere move close to one another and collide.

Hint 8

Front 9

Subduction zones

Back 9

subduction is the process that takes place at convergent boundaries by one tectonic plate it moves under another tectonic plate and sinks into the mantle as the plates converge.

Hint 9

Front 10

Transformed boundary

Back 10

A place where plates slide past eachother
