What does seafloor spreading form?
Mid-ocean ridge system.
What is the difference between a rift valley and a mid ocean ridge and what kinds of boundaries do they form at?
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
How do the mantle's convection currents move to form a mid-ocean ridge?
The mantle's convection currents move in the mantle in the form of magma which creates the mid-ocean ridge. Mid-ocean ridges are found in every ocean in the world and when the currents erupt as lava the eventually cool and create a crust.
Where part of a mid-ocean ridge above water?
The Mid-Atlantic Ridge comes up above the surface of the water to form the island Iceland.
What do underwater volcanic eruptions cause?
Underwater eruptions cause tsunamis and cause lava to form and underwater ridge.
What cause new material to form at a mid ocean ridge on the ocean floor?
New material forms on the ocean floor of the mid-ocean ridge due to plate tectonics and volcanic activity. Volcanic eruptions deposit cooled magma on the ocean floor.
What form a mid ocean ridge?
tectonic plates
What does seafloor spreading form?
Mid-ocean ridge system.
What can divergent boundaries form?
A rift zone on land, a mid ocean ridge under the ocean.
Which features form the longest mountain ranges on Earth?
Ocean Ridge
What does a mid ocean ridge form along?
A divergent plate boundary

How does new mid-ocean ridge form?
a mid-ocean ridje is an undersea mountain chain where new ocean floor is produced;a divergent plate boundary under the ocean.
When does a mid ocean ridge form?
It forms when the 2 plates converge or come apart
