the world and in relation to tectonic plate boundaries. For example you have highly destructive and explosive volcanoes often found along destructive plate boundaries because of increased pressure within the subduction zone. An example of this is the Philippines‚ which is situated above a destructive plate boundary and this leads to numerous and highly destructive volcanic eruptions. You also find volcanoes along constructive plate boundaries where the plates are moving apart and this is creating

The Alps are the youngest and highest mountain system in Europe. They stretch across the western and southern part of the continent in a broad arc. The mountain range startsnear the Mediterranean Seaon the border between France and Italy. Then it curves north- and eastward through northern Italy‚ Switzerland Liechtenstein‚ southern Germany‚ Austria and Slovenia. The Alps are about 1‚000 km long‚ the broadest section over 260 km wide. The highest peak‚ Mont Blanc‚ situated on the border between

occur both on land and sea.They may occur at areas where plates collide (subduction zones/ convergent plate margins) ; where plates slide past eachother along fault lines (transform plate margins) or due to volcanic eruption. Earthquakes may be of three different categories: * Tectonic – movement in the earth’s crust due to sudden movement along fault lines. * Plutonic - occurs deep within the subduction zone of colliding plates. * Volcanic – earthquakes accompanied by molten lava

roles do plate tectonics play in the geomorphology of Pacific Islands? The earth’s crust is made out of plate tectonics. Each plate has a defined boundary and direction it moves. The plates in Earth’s crust perform two actions; they submerge under each other or they spread out. The Pacific Plate is the largest plate and it borders around many plates. The Pacific Plate moves northwest. New crust is formed from magma outpours‚ which are a result of the zones spreading. The tectonic plates created the

2. Summarize plate tectonics. It explains the theory of how the changing surfaces of the earth are formed. 3. What are convection currents and what is their role in plate tectonics? Convection currents are the rise and lowering of heat in te earths mantle like a boiling pot of water. The heat is denser at the bottom of the pan it rises the falls to the bottom and reapaets it self. This rising and dropping is the effect that why the plates move. 4.

The Galapagos Islands are located on the equator west of the South American coast. Like many oceanic islands‚ they are formed by a mantle plume or hotspot like Hawaii. A major subduction zone currently sits under the islands‚ the two plates that are subducting beneath the South American and Caribbean plates are the Nazca and the Cocos plates. The Galapagos

The three types of plate boundaries are: * Divergent boundaries are a region where the rigid plates are moving apart‚ typified by the oceanic ridges * Convergent boundaries are a boundary in which two plates move together * Transform boundaries are a boundary in which two plates slide past each other without creating or destroying lithosphere 5.
