2I) Where Mountains Form Mountain Belts1) Most Mountains are associated with convergent plate boundaries2) Most mountains occur in long belts that follow convergent boundaries3) Himalayas lie along a current convergent boundary4) Appalachians are in the middle of a plate – but were formed by converging plates over a billion years ago.
3B) Continental Margins (land and sea meet) Active Marginsa) occur along plate boundariesb) mountain building takes placec) Himalayan Mountains2) Passive Marginsa) stable areas away from plateboundariesb) Appalachian Mountains
4c) Passive margins provide the materials or sediments from which mountains form.ActivePassive

6V) Mountain FactsA) Himalayan Mountains1) The largest/highest mountain rangeB) Mid-Atlantic Ridge1) The longest mountain range
7Factors that affect mountain Deformation Deformation – all changes that occur to a body of rock.TemperaturePressureRock TypeTime exposed to pressure or heat
8Tectonic ForcesMountains are the result of rock that is permanently deformed by stress/forcesThree types of forces cause three types of faults:TensionCompressionShear
36b) There are two types of dome mountains: Individual, isolated structures that form in layers of sedimentary rock.b) There are two types of dome mountains:Plutonic Domean igneous intrusionpushes up existing rocklayers.
