History of Earth

Theory that Earth is composed of large pieces that move around the outside of Earth

• sea floor spreading

• plate tectonics

• mantle

• rock cycle

Formation of oceanic crust through the movement upward of magma at a mid-oceanic ridge

• sea floor spreading

• plate tectonics

• mantle

• rock cycle

Check all of the following that are TRUE about DIVERGENT plate boundaries

• tectonic plates move away from each other

• tectonic plates move towards each other

• this is where new crust is formed

• mid-oceanic ridges are formed here

Check ALL that are true about CONVERGENT plate boundaries

• plates slide past each other (rub sides)

• plates move towards each other

• mountains form at these plate boundaries

This is the plate boundary where tectonic plates slides past each other (rub sides)

• divergent

• convergent

• subduction

• transform

This is the plate boundary where one tectonic plates moves beneath a different part of crust

• divergent

• convergent

• subduction

• transform
