Techtonic Hazards
Conservative Plate Boundries
Ocean ridges
Moving apart from each other to create a ridge such as the Mid-Atlantic ridge
Rift Valleys
Tearing plates apart such as the East African Rift Valley.
Shield Volcanoes
Small scale landforms
Fault Lands
Large Scale landform found along a conservative plate boundary.
Crust types
Continential
Older
Less denser
Cannot sink In the mantle
Made of granite
Thicker
Oceanic
Younger
Denser
Sink In the mantle
Made of basalt
Thinner
Sub-ducting Destructive plate bountaries
Composite volcano
As the plates collide, the oceanic plate is forced beneath the continental plate. Magma escapes through the weakness In the rock and rises up though a composite volcano
Destructive collision Plate Boundaries
Fold mountains
pressure crumples the crust and makes a fold volcano
Both plates push into each other making them rise
