Earth layers
|
Core, Crust, Lithosphere, uppermost mantle, and Asthenosphere.
|
|
Core
|
The deepest inner portion of earth, representing 1/3 of it's entire mass (differentiated into two zones).
|
|
Crust
|
Earth's outer shell of crystalline surface rock, ranging from 5 to 60km (3 to 38mi) in thickness from oceanic crust to mountine ranges.
|
|
Uppermost mantle
|
Is solid and makes up the lithosphere, approximately 45-70km thick.
|
|
Asthenosphere
|
Region of the upper mantle right blow the Lithosphere, is known as the plastic layer, and flows very slow under extrem heat/ pressure.
|
|
Rock cycle
|
The interelationship among the three rock forming processes, and it shows how each rock could transfrom to other rocks.
|
|
Main rock type and formation
|
Igneous, Sedimentary, and Metamorphic.
|
|
Igneous rock
|
Has soildified and crystallied from from hot molten state (either magma or lava).
|
|
Sedimentary rock
|
Formed from the compaction, cementation, and hardening of sediments derived from other rocks.
|
|
Metamorphic rock
|
Existing igneous and sedimentary rock that has undergone pround physical and chemical changes under increse presure and temperature.
