Rock Cycle Processes
Metamorphic to Igneous
melting, hardening, & cooling
How does Metamorphic Rock form?
when heat & pressure are applied to other rock types
Lava
the magma that reaches the surface of the earth
Convergent Boundary
when to plates collide
Intrusive
Igneous Rock that cools slowly and has large crystals
Igneous to Sedimentary
eroding, layering, compacting, & cementing
How is Igneous Rock formed?
when magma cools and hardens it
Lithosphere
the crust and solid, upper portion of the mantle
Divergent Boundary
when two plates pull apart (divide)
Extrusive
Igneous Rock that cools quickly and has small crystals
Sedimentary to Metamorphic
heat & pressure
How is Sedimentary Rock formed?
when small parts of other things come together
Seamount
an undersea volcanic mountain found on the ocean floor
Transform Boundary
when plates slide past each other
Upwelling
the movement of cold, deep ocean water to the surface
Metamorphic to Sedimentary
eroding, layering, compacting, & cementing
What are some examples of Metamorphic Rock? (3)
marble, slate, gneiss
Polarity
having two opposite poles (positive/negative or north/south)
El Nino
a climate event in the Pacific resulting in warmer water
Subduction
when which one lithospheric plate goes under another
Sedimentary to Igneous
melting, cooling, & hardening
What are examples of Igneous Rock? (3)
obsidian, granite, basalt
Deep Ocean Currents
a stream of water that flows deep beneath the ocean’s surface
Coriolis Effect
the way Earth’s rotation affects winds & ocean currents
Abyssal Plains
a large, nearly flat region on the ocean floor
