Question | Answer |
The 4 layers of the Earth | Crust, Mantle, Outer Core, Inner core |
Crust (size, made of..., makes up...) | Thinnest layer, made of rock, makes up part of the (Lithosphere) |
Continental Crust (Made of, Density, Thckness) | Made of granite, less dense, thiner |
Oceanic Crust ( made of, density, thickness) | Basalt, more dense, thicker |
Mantle (thickness, made of) | Thicker Layer, made of magme |
Asthenosphere | upper part of mantle, convection cells |
Outer core(made of) | Liquid, iron nickel |
Inner core (made of) | Solid Iron, nickel |
As depth increases, | temputure increases |
Plates | Pieces the lithosphere is broken up into |
Lithosphere | big solid slabs of rock between earths crust and mantle |
Plate tetonics | magma rises in the mantle which moves to the lithospheric plates |
Plate boundries | edges where plates touch |
Divergent | PLates mover away from eachother |
Convergent | When plates move toward 1 another |
Transfor | plates move side to side |
Collision | 2 contenental plates collide to form moutains |
Subduction | 2 plates collide and 1 is forced under another to produce a deep sea trench and island chaines. One ocean plate and 1 continental plate collide with the ocean plate subducting beneath to produce volcanos. Crust is melted as it subducts ina down motion |
