Convergent boundary (continental- continental)

Himalaya Mountains

200

A deep valley that forms where two continental plates diverge 

rift valley

200

mid ocean ridges OR seafloor spreading

200
two plates that slide next tot each other.
transform
300
A theory explaining how the plates that make up the Earth’s crust move over the mantle.
Plate Tectonics
300

Most active geologic area on earth

Ring of Fire

300

When the ocean floor diverges and creates new crust

mid ocean ridge

300

Where is the oldest crust found on the ocean floor? 

AT the edge of the continents 

300
Two plates that move toward each other.
convergent
400
The part of the Earth’s upper mantle where magma rises and falls.
Asthenosphere
400

Where 2 ocean plates diverge

Mid Atlantic ridge OR Iceland

400

a crack in the earth's crust resulting from the displacement of one side with respect to the other

fault

400

Name the specific boundary type(s) that destroys crust

Subduction zones /convergent ( O-C) or (O-O)

400
A subduction zone is an example.
Convergent
500
The rigid outer part of the Earth. It includes the Crust and upper mantle.
Lithosphere
500

Convergent boundary (oceanic- continental)

Cascade Volcanic Mountains OR northwest coast of USA or Mt St Helens

500

Created during subduction zones where the two different crusts meet

(oceanic) trench

500

The crusts of the Earth float on this layer ( must name specific layer)

Asthenosphere

500
The Mid- Atlantic ridge is an example.
Divergent
