Plate Tectonics Flashcards
Subduction
Heavier oceanic crust goes be each lighter crush which leads to new island arcs like New Zealand or mt. Ranges where magma is released ljke The Andes
Plate tectonics
Model/theory that explains why continental plates move and how they interact
(Sit on mantel(liquid))
North American plate includes part of asia Greenland and North America & we can investigate how they interact in changes in mt.ranges and land mass
Continental plates colliding
Increase in continental plate thickness (smash , compress go up ) and eventually to new mountain ranges like Himalayas
- not all have subduction
- increase in altitude could be from change in habits
Oceanic hot spot
Hot rock rises from the mantel and breaks through oceanic crust created by the movement of the plate over the area creating a chain of islands
Ex)Hawaii islands
Rift valleys
Two continental plates move apart from eachother forming deep lakes and valleys
Ex) lake Victoria
