Seafloor Spreading / Subduction

The process that adds crust to the ocean seafloor 

what is evidence for convection currents

The San Andreas Fault is an example of a transform boundary

the Ring Of Fire is at

this ridge separates the western hemisphere from the eastern hemisphere

the pacific ocean is 

here, molten material rises from the mantle and erupts, then spreads out, pushing old rocks out

convergent boundaries include tectonic plates that move away from eachother

this ridge is pushing the nazcan plate upwards and the atlantic plate down

what moves from the mantle to the crust of the Earth

what is the area around the Pacific Plate that has volcanic and EQ activity?

divergent boundaries move away from each other

what is evidence for earthquakes

the longest chain of mountains in the world is called?

what is going on inside of the mantle

where convergent boundaries interact and one tectonic plate moves underneath the other

what is evidence of subduction

the Atlantic Ocean is 

here subduction allows parts of the ocean floor to sink back into the mantle
