crystal plate a is moving away from crystal plate b whats is the expected average rate of change in position between a and b a. a few cm/year b. a few m/month c. a few mm / century d. a few mm /day
is that the mid-ocean is close to the ridge ans to the fault
New oceanic crust and unlithified sediments.
Midocean ridges are areas where continents broke apart. Midocean ridges are closest to the landmasses in younger oceans. One example where a midocean ridge intersected a landmass is the Arabian sea, which was formed by the pulling apart of the Arabian Peninsula and Africa.
One of the midocean ridges is, but others are in other oceans, seas, and bays.
You would expect to find a fold mountain range at a convergent or collision boundary rather than at a divergent boundary such as a mid ocean ridge.
a rift valleyis a dip in the ocean floor a mid ocean ridge is a mountain chain formed on the ocean floor . Rift valley - divergent boundary MidOcean Ridge Convergent Boundary
friction - convection currents in the mantle drag the plates away from the hot rising zone below the ridgegravity - gravity pulls down on the cold dense plate being subducted under the continent, dragging the plate away from the ridge

Older, as it moves away from the mid-ocean ridge the sediment gets thicker and older

MidOcean Partners was created in 2003.
Transform and normal faults form along mid-ocean ridges such as the Mid-Atlantic ridge.
The midocean ridges are the spreading centers where the plates are moving apart. The seamounts are extinct volcanos produced as the plate passed over a mantle hotspot.

The motto of Palmer Ridge High School is 'Ignite, Encourage, Engage, and Expect Excellence'.
it is known as sea floor spreading. this is when the oceanic plates diverge or move apart which causes the magma from the mantle to rise forming new sea floor.
