Plate Tectonics

Plate Tectonics is the study of the theory that the earth is composed of many layers. The composition of the earth can be likened to that of an egg, with the outer edge, the shell, and the core, the yolk. The top layer (the crust), the layer which we walk on, is comprised of many slabs of earth, each independant of each other. The movements of these plates are what give us earthquakes and volcanoes. This mind map explains some of the concepts of Plate Tectonics.

Plates

Conservative

Plates slide alongside.

Products, Volcanoes, Earthquakes

Constructive

Two plates are diverging (moving apart).

(Mid Atlantic Ridge)

Collision

Products, Fold Mountains, Earthquakes

Hazards

Earthquakes

Pressure built up is released and produces very strong seismic waves.

Measured on Richter scale

Volcanoes

Extinct, Unlikely to ever erupt again, Devil's Tower

Dormant, Hasn't erupted in 2500 years, Santorini

Active, Erupted recently, Mt Etna

Composite Volcano, Mixture of Lava and Ash

Shield Volcano, Lava basic and runny, flows quickly and creates flat volcanoes.

Dome Volcano, Lava acid and thicker, flowing slower and hardens quickly to form steep-sided features.
