What landforms are at different plate boundaries?
... What landforms are found at different plate boundaries? • Both fold mountains and ocean trenches result from plates moving together. If both landforms occur in the same area, they are found in association with subduction. • If fold mountains occur by themselves, they are in areas where collision i ...

How the Andes Mountains are used
... The Andes Mountains run the length of the West Coast of South America, rising in the North in Colombia and finishing in Chile and Argentina in the South. They are world's longest mountain range running for over 7,000km and covering 6 countries. The mountains have been formed as a result of the conve ...

Effects of Plate Tectonic Movement
... i. The Fault-block Mountains or block mountains are created when faults or cracks in the Earth's crust force materials or blocks of rocks upward or down. The uplifted blocks are Block Mountains or horsts. The intervening dropped blocks are called graben, which can be small or form rift valley system ...

Appalachian Mountains
The Appalachian Mountains (/ˌæpəˈleɪʃɨn/ or /ˌæpəˈlætʃɨn/, French: les Appalaches), often called the Appalachians, are a system of mountains in eastern North America. The Appalachians first formed roughly 480 million years ago during the Ordovician Period and once reached elevations similar to those of the Alps and the Rocky Mountains before they were eroded. The Appalachian chain is a barrier to east-west travel as it forms a series of alternating ridgelines and valleys oriented in opposition to any road running east-west.Definitions vary on the precise boundaries of the Appalachians. The United States Geological Survey (USGS) defines the Appalachian Highlands physiographic division as consisting of thirteen provinces: the Atlantic Coast Uplands, Eastern Newfoundland Atlantic, Maritime Acadian Highlands, Maritime Plain, Notre Dame and Mégantic Mountains, Western Newfoundland Mountains, Piedmont, Blue Ridge, Valley and Ridge, Saint Lawrence Valley, Appalachian Plateaus, New England province, and the Adirondack provinces. A common variant definition does not include the Adirondack Mountains, which geologically belong to the Grenville Orogeny and have a different geological history from the rest of the Appalachians.
