| Question | Answer |
| layers of the earth | |
| oceanic- thinner, less dense, basalt Continental- thicker, more dense, granite | |
|
Image:
Th (binary/octet-stream)
|
Lithosphere made up of crust and upper mantle |
|
Image:
Moho (binary/octet-stream)
|
MOHO between crust and rigid mantle |
|
Image:
Esrt (binary/octet-stream)
|
Most common elements in crust |
|
Image:
Mantle (binary/octet-stream)
|
thickest layer, part solid, part liquid |
|
Image:
Asth (binary/octet-stream)
|
Plastic mantle layer in which convention occurs |
| convection currents in the asthenosphere move the plates around | |
|
Image:
Core (binary/octet-stream)
|
Believed to be entirely liquid iron and nickel. Evidence is that S waves do not pass through this layer |
| inner core solid iron and nickle highest density | |
|

Esrt10 (binary/octet-stream)
|
properties of earth's interior |
|

Graph (binary/octet-stream)
|
temperature and pressure increase as you travel deeper into the earth |
| The lithosphere of the earth is broken up into plates which “float” on the plastic asthenosphere below | |
| Theory developed in the mid-1900’s that explained all geologic observations including mountains, earth- quakes, volcanoes, and trenches | |
| convergent move towards each other | |
|
Image:
Diver (binary/octet-stream)
|
Divergent move away from each other forms a ridge |
|
Image:
Trans (binary/octet-stream)
|
Transform slide past one another earthquakes found here |
|
Image:
Subd (binary/octet-stream)
|
Subduction zone (continental crust and oceanic crust) The oceanic crust beneath because it is more dense Volcanoes, mountains, earthquakes and trenches |
| HOT SPOTS • There are locations on earth, away from plate boundaries, where volcanic activity occurs | |
|
Image:
Fold (binary/octet-stream)
|
fold |
|
Image:
Faults (binary/octet-stream)
|
fault |
| Collision zone (continental crust and continental crust) colliding plates with same density crumple up as they collide • Mountains and earthquakes | |
| Island Arc (oceanic crust and oceanic crust) two oceanic plates collide and one usually subducts Volcanic islands, earthquakes and trenches |
