Western mountains in USA

•Oceanic plate Farallon subducted under North American plate – 65 ml years ago•Extensive volcanism and rising of Rockies •Colorado plateau•Basin- range topography due to faults

O-C collision of ancient time

Farallon plate

North American Plate

•15 ml years ago – Farallon oceanic plate almost subducted under North American plate•Pacific and N.American plate came into contact•Farallon plate was moving eastward

Pacific- N.American transverse Boundary

•Now Pacific plate was moving north-west•North American plate moves south – south west direction•Result – San Andreas fault

Pacific- N.American transverse Boundary

•Remnant of Farallon plate- Juan de Fuca plate continued eastward movement•Divergence between Juan-de-Fuca plate and Pacific plate• Juan De Fuca plate subsiding below North American plate

O-C plate collision in recent time

•Subduction of oceanic plate => Volcanism•Rising of volcanic fold mt. –cascade range•Rising of Sierra Nevada in last 5 ml (orogeny started around 120-80 ml years ago)

O-C plate collision in recent time

• Lava flow – between 17-6 ml years ago•Hot spot beneath the Columbia plateau - North American plate moves south-west•Columbia-snake plateau•Basaltic lava plateau (like Deccan lava plt.)• Yellow stone national park – geysers

Hot Spot Volcanism in USA

•Sierra Nevada –Gold•Fold mountains – volcanism- still uplifting - EQ•Cascade range – part of Pacific ring of fire – volcanic rocks – rich in potassium – potential geothermal power

Western mountains: resources

• Rockies: young fold mountains (85 to 55 ml years ago)•Copper, Gold, Lead, silver, Zinc, Tungsten

•Ohio, Indiana, Illinois, Iowa and Missouri• Intensive crop and livestock farming•Most of the corn is used to raise or fattening livestock- hogs (pigs) and poultry• cattle rearing for meat and dairy products

Corn belt

• Intensive animal farming = factory farming•Milwaukee city meat processing•Chicago – meat packing•Wisconsin state - dairy

Animal Rearing in USA

•Cotton plantation system•Hybrid cotton variety with mechanized farming•Cotton exported•Textile industries – labour intensive – US import from Bangladesh, Pakistan and India

Cotton belt

•South – winter wheat (hard), north – spring wheat (soft)•Truck farming belt•Very high productivity per person•Highly subsidized farming
