True or false sea floor sediments gradually thicken away from a mid-ocean ridge?
true
How are ridge pull and slab pull related?
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.
When the force of gravity moves a plate downward and away from a ridge?
It is a process called ridge push.
What does the sediment the is closer to mid ocean ridge compare to sediment that is farther away?
The closer the sediment is to the mid-ocean ridge, the younger it is. The oldest bedrock is found the farthest away from it.
What direction do plates move in relation to ridges?
Depends on the type of plate boundary, at a mid-ocean ridge the plates move away from eachother. Ridges can also occur as a result of plate collision where the top layer of lithosphere is scraped off the subducted slab, this is called an accretionary prism.
What a ridge push?
Ridge push is a gravitation force that causes a plate to move away from the crest of an ocean ridge, and into a subduction zone.
True or false sea floor sediments gradually thicken away from a mid-ocean ridge?
true
What causes the oceanic lithosphere to move away from the mid-ocean ridge?
it is caused by convection currents
What is a good sample sentence for the word crest?
I really enjoy hiking along the crest of that ridge because it is so colorful in the springtime. Sailing away on the crest of a wave is like magic.
What is a ridge push?
Ridge push is a gravitation force that causes a plate to move away from the crest of an ocean ridge, and into a subduction zone.
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.
What evntually happens to seafloor that is carried away from a mid-ocean ridge?
Seafloor continues to move away from the mid-ocean ridge and eventually comes into contact with another plate boundary. Ocean plates subduct underneath continental plates and are forced down into the lithosphere

What supports the theory of continental drift?
The chain in The Mid-Atlantic ridge is part of the longest mountain chain in the world. Which new oceanic lithosphere is created as older materials are pulled away.
Why moon does not have lithosphere?
Because the moon is in the exosphere far away from our planet and the lithosphere
What is an underwater mountain chain formed where new crust is created by seafloor spreading called?
The process of sea-floor spreading created the lithosphere under the Atlantic Ocean. As North America and South America moved away from Europe and Africa, the resulting crack was filled by mantle material, which cooled and formed new lithosphere. The process continues today. Molten mantle materials continually rise to fill the cracks formed as the plates move slowly apart from each other. This process creates an underwater mountain chain, known as a mid-ocean ridge, along the zone of newly forming lithosphere.
How far away is the lithosphere?
You're standing on it. The lithosphere is the crust and upper mantle of the earth.
