Seafloor Spreading and convection current

4. -the theory that earth outer shell is though is divided into large slabs of solid rocks called plates that glide over earth mantle the rocky inner layer above earth cure
6. -contact between two plates that slide herizontally past one another commonly connecting two mid ocean ridges
8. -the upper most layer of the oceanic portion of the tectonic plates
12. -the solid outer part of the earth
13. -the upper layer of the earths mantle below the lithosphere in which there is relatively low resistance to plastic flow and convection is though to occur
14. -where an extre heavy plate a plate that is extremely heavy even gravity act upon it and pull them apart

1. -a theory that says the continental land masses were drifting across the earth sometimes plowing through oceans and into each other
2. -a layer inside a planetary body bounded below by a core and above crust seafloor spreading the formation of new areas of oceanic crust, which occurs through the upwelling of magma at mid ocean ridges where ocean crust is created
3. -the hot fluid or semi-fluid material below or within the Earth's crust
5. -the formation of of new areas of oceanic crust which occurs through the upwelling of magma at mid ocean ridges and it's subsequent outward movement on either side
7. -is a large fractures in the seafloor where the plate slip each other 12.mid ocean ridge the creation of new crust, subduction on the other hand destroy old crust
9. -is a process of recycling it returns the material back to the mantle or one of the driving forces that allow the changes in the plate movement
10. -a proposed driving force for plate motion in plate tectonic that occurs at mid ocean ridges as the result of the rigid lithosphere sliding down the hot cross
11. -the location where two plates meet
