APES 4.1 Plate Tectonics

Core

1st

• Solid & rlly hot center of earth

Mantle

2nd

• liquid layers that stays liquid b/c of core’s heat

Asthenosphere

3rd

• solid & flexible outer layer of mantle

Lithosphere

4th

• thin & solid layer of rock on top of asthenosphere

Crust

5th

• outer layer of lithosphere and earth surface

Divergent plate boundary

when plates pull apart

• creates valleys

Convergent plate boundary

When plates push together

• creates mountains

Transform boundary

when plates slide past each other

• creates earthquakes

Convention cycle

Magma rises and cools, This separates oceanic plates and creates a new lithosphere. (some?) oceanic plates push down and melt into magma which starts the cycle again

• creates volcanos and mid ocean ridges

Oceanic - Oceanic

When an O slides beneath (or subduct’s) an O it creates vocation and off shore trenches

Oceanic - Continental

When an O slides beneath (or subduct’s) a C it melts back into magma

Continental- Continental

When a C slides beneath (or subduct’s)Ring a C it forces the earths crust up which creates mountain ranges

Ring of Fire

A line/ pattern of volcanos along the pacific plate (b/c there’s a lot of convergent zones which pushes magma to the surface)

Transform Faults

Places where earthquakes are most likely to happen

Hotspots

Areas of rlly hot magma rises to the lithosphere
