Do Ocean sediments become younger or older away from midocean ridges?
Older, as it moves away from the mid-ocean ridge the sediment gets thicker and older
At locations where sea floors spreading occurs rock is moved away from a mid-ocean ridge what replaces the rock as it moves away?
continental crust.
When the force of gravity moves a plate downward and away from a ridge?
It is a process called ridge push.
Why does the lithosphere thicken away from the ridge crest?
Cooling as rock moves away from the ridge crest causes the rock to become increasingly rigid.
What is a force that is causing the plates to move at a midocean ridge?
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
Is it true that as the new seafloor moves away from the ridge and becomes hotter it moves upward and forms still higher ridges?
No. The rock cools down as it moves away and sinks deeper.
Is it true that as oceanic crust moves away from the mid-ocean ridge. it cools and becomes more dense?
True.
Is it true oceanic crust moves away from the mid ocean ridge it cools and becomes more dense?
yes
What happens when you move roks away from the ocan ridge?
They increase in age and density, and decrease in temperature.
In which location would an ocean ridge?
The mid-ocean ridge is almost in all of the oceans
How are ridge and slab pull related to convection in Earths mantle?
they are related because they all have to do with the oceanic lithosphere.The convection causes the lithosphere to move sideways and away from the midocean ridges.The ridge push makes the oceanic lithosphere slide downhill under the force of gravity. The slab pull:the old lithosphere is denser than asthenosphere so, the edge of the tectonic plates that contains oceanic lithosphere sinks and plls the rest of the tectonic plate.
Why are oceans far away form a ridge?
cuz rocks come up from the ridge and create land by the ridge
