Which term describes the process that creates new oceanic crust at mid-ocean ridges?


A.
convergent boundary

B.
palaeomagnetism

C.
seafloor spreading

D.
tectonic motion

Answer 1

please help me

Answer 2

When plates separate, basically what is underneath the plates (very hot) is exposed, and the seawater cools that, creating new oceanic crust

Answer 3

sea floor spreasading

Answer 4

I believe the answer is C. A is where the plates collide, creating ridges. B is abour magetism

Answer 5

learned about this stuff a year ago

Answer 6

i have more questions

Answer 7

Which force is responsible for seafloor spreading?

A.

C.
convection in the crust

D.
gravity in the crust

Answer 8

Movement in the mantle, I believe, causes this .. So C, I think.

Answer 9

This movement is caused by convection currents from the core/mantle.

Answer 12

so what is the letter you think

Answer 13

Answer 14

because the mantle moves upward and the last definition
