2 I) 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.
3 B) 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
4 c) Passive margins provide the materials or sediments from which mountains form.ActivePassive
5 Major mountain systems are related to plate tectonics. Most mountains IV) Mountain BuildingMajor mountain systems are relatedto plate tectonics. Most mountainsform along convergent boundariesWhere else wouldyou find mountains?Divergent BoundariesHot Spots
6 V) Mountain FactsA) Himalayan Mountains1) The largest/highest mountain rangeB) Mid-Atlantic Ridge1) The longest mountain range
7 Factors that affect mountain Deformation Deformation – all changes that occur to a body of rock.TemperaturePressureRock TypeTime exposed to pressure or heat
8 Tectonic ForcesMountains are the result of rock that is permanently deformed by stress/forcesThree types of forces cause three types of faults:TensionCompressionShear
36 b) 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.
