Plate Boundary 0.0 / 5 ? GeographyPlate tectonicsA2/A-levelOCR Created by: [email protected]Created on: 04-10-16 11:15 An Constructive Boundary Oceanic and Oceanic Crust Moving away from eachother Example: North America and Eurasian Plate- forming the Mid-Atlantic Ridge Major Landforms created: Iceland - Island Arc Ridges, Mid Oceanic Underwater Volcano Rift valley (Continental) Tectonic Activity: Volcanos Sea-floor spreading Doming and faulting Rising magma 1 of 4 The Destructive Boundary Continental and Oceanic Crust Moving towards eachother Example: South American and Nazca Plates- forming the Andes and a deep sea trench, the Peru-Chile trench Major Landforms: Volcanoes Deep ocean trenches Mountain range/ Fold Mountains Tectonic Activity: Subduction Melting of descending plate Powerful earthquake caused by friction Volcanic eruption 2 of 4 A Collison Boundary Continental and Continental Crust Moving towards eachother Example: Indo-Australian and Eurasian plate- forming the Himalayas Major Landforms: Fold Mountains Tecontic Acvtivity: Big Earthquakes No volcanoes 3 of 4 A Conservative Bounddary Also known as a 'Transform plate' Continental and Continental Crust Moving side by side Example: San Andreas Fault- North American and Pacific Plates Major Landforms: No major landforms are found here Tectonic activity: Big earthquakes No volcanoes 4 of 4
