|
Definition
Crust:
Mantle: Lower and Upper Layer
Core: Solid inner portion
Solid portions of crust and upper layer mantle make up litosphere
Asthensophere is under it

Earth Chemical Composition |
|
Definition
- Earth core consist of hot iron and forms of nickel
- Mantle consists of iron, magnesium, and calcium
- Crust covers the mantle, lighter rock
|
|
|
Term
|
Definition
- When layers of sedimentary rock are pressed together by continental plate movements
- Folds upwards are anticlines, downwards are synclines
Alps and Himalayans |

|
Term
|
Definition
Created when tectonic plate movement produces tension that result in displacement. Southwest US |
|
|
Term
|
Definition
Like boiling water, heating things rise up when they cool and slowly go back down. A cycle to reach equilibrium |
|
|
Term
|
Definition
- That the lithosphere, solid portion of mantle and earth crust) consists of Major and minor plates
- These plates are on top of and move with the viscous upper mantel because of the heating below

Definition
Plates that spread apart and form new crust |
|
|
Term
|
Definition
Process of subduction that causes one plate to go under another |

Term
|
Definition
dip-slip: vertical movement along the fault long (wall above fault plane moves down)
strike-slip: horizontal movement across the plane
Oblique-Slip: Both vertical and horizontal
