- earth structure
- core
- mantle
- crust
- tectonic plates
- plate boundary types
- destructive
- moving towards
- ocanic sink
- ocanic plate destroyed in mantle
- friction at subduction zone=earthquake
- volcanoes form
- ocean trenches form
- volcanoes form
- friction at subduction zone=earthquake
- ocanic plate destroyed in mantle
- ocanic sink
- continental and oceanic
- moving towards

- ocanic plate destroyed in mantle
- ocanic sink
- moving towards
- collision
- 2 continental plates
- example- Himalayas
- nazca and S.America
- moving towards
- constructive
- moving away
- Mid atlantic ridge
- magma rise-fill gap
- cool-create new ccrust
- moving away
- Mid atlantic ridge
- moving away
- cool-create new ccrust
- moving away
- conservative
- sideways move
- same direstion, different speed
- san andreas fault
- no crust created or destroyed
- sideways move
- destructive
- plate boundary types
- very thin 20km
- 2 types
- oceanic
- thinner
- denser
- sink
- younger
- continentle
- thicker
- less dense
- don't sink
- older
- oceanic
- plated move due to convection current in mantle
- tectonic plates
- semi-molten rock,move slowly
- crust
- solid iron and nickle

- Fold mountains
- process
- river deposit sediments in geosyncline depressions
- sediments compressed
- sedimentary rocks form
- examples- sandstone, limestone
- plates compress
- sedimentary rocks fold upwards
- sedimentary rocks form

- river deposit sediments in geosyncline depressions
- plate boundary
- destructive
- collision
- characteristics
- high mountain
- rocky , steep slopes
- high- snow and glacier
- valleys- lakes
- land uses
- farming
- high slopes- graze animals
- lower grow rops
- HEP power
- steep sided, high lakes
- mining
- metal ores
- zig zag roads to access
- tourism
- scenery
- winter sports
