How Landforms Are Created

Plate Tectonics

Large moving slabs of rock slide slowly over a layer of the mantle Plate Tectonics

The Theory of Continental Drift

Earth ~200 million years ago

Alfred Wegener’s Evidence: The presence of fossils only over small areas of now separate continents

3 Types of Plate Boundaries Divergence Convergence Transformal

DIVERGENCE

Divergence

Process where new oceanic crust is formed through volcanic activity and then gradually moves away from the ridge Sea-Floor Spreading

CONVERGENCE

Forms mountains, e.g. European Alps, Himalayas CONVERGENCE

CONVERGENCE ZONE

Shows the South American and Nazca plates colliding

Transformal

No mountains are created Transformal No mountains are created

What are Hot Spots???

What are Hotspot Volcanoes? Hot mantle breaches the surface in the middle of a tectonic plate The Hawaiian island chain are examples of hotspot volcanoes.

Has a major impact on countries that are close to it Examples: Earthquakes, Volcanic Eruptions Pacific Ring of Fire

Hawaii was formed by volcanic activity
