Is the pattern of magnetic stripes in rocks on either side of a mid-ocean ridge the same?
its the same on either side of the mid-ocean ridge
How do strips of magnetized rock on the ocean floor provide evidence of sea-floor spreading?
Strips of ocean-floor basalt record the polarity of earth's magnetic field at the time the rock formed. These strips form a pattern that is the same on both sides of the mid-ocean ridge. the pattern shows that ocean floor forms along mid-ocean ridges and then moves away from the ridge.
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.
What landforms are found in ocean?
The same kind of landforms found on land. Oceans are just lands that are real low in elevation, as water is just sitting on top. Think of oceans as bathtubs or pools; the water there isn't permanent. This means the land is the same, so there are volcanoes, mountains, plateaus, valleys, etc. underneath the oceans.
What evidence helped support the theory of seafloor spreading?
The western coast of Africa and the eastern coast of South America, are of the same shape. The line of volcanic activity (the mid-Atlantic ridge) between the continents is of this same shape, as are the series of lesser ridges on each side of this central ridge. The easterly and westerly spreading of Iceland, which is located directly over this same ridge line. The fossil records of the continents on both sides of the ridge are the same in terms of species and time frame. The related location of certain geologic features, like coal deposits and other structures.
What is an ocean ridge formed by?
An ocean ridge is and underwater mountain range which is formed in the same way as an above water mountain range, by plate tectonics.

When a plate at a mid ocean ridge responds to gravity by down a slope it is called?
ridge push but figure it out yourself next time because i have had this same question on a test. (Is saying suspiciously.)
What can you infer about continents on opposite sides of the same mid-ocean ridge?
That at one point they were much closer to each other.

How does the ridge-rift in the pacific ocean differ from that in the Atlantic ocean?
Pacific ocean is shrinking due to plate tectonics while Atlantic is increasing in size. Looked up the same question just now for a final tomorrow.
How old are the oldest rock of the Atlantic sea floor?
The Mid-Atlantic Ridge is part of the greater mid-ocean ridge system, an underwater mountain range that is over 40,000 miles long. The age of new rock closest to the ridge would be roughly the same anywhere along the ridge.
What are the steps in process of sea floor spreading?
The sea-floor spreading begins at the mid-ocean ridge, which forms along a crack in the oceanic crust. Along the ridge, molten material that forms several kilometers beneath the surface, rises and erupts. At the same time, older rock moves outward on both sides of the ridge. As the molten material cools, it forms a strip of solid rock in the center of the ridge. When more molten material flows into the crack, it forms a new strip of rock.
Mid-ocean ridges are formed by?
_Seafloor Spreading_ 1. Hot, molten rock is forced upward toward the seafloor at a mid-ocean ridge. 2. Molten rock pushes sideways in both directions as it rises, moving the mantle with it. 3. Molten rock flows onto the seafloor and hardens as it cools. 4. New seafloor moves away from the ridge, cools, becomes denser, and sinks. - Maylin _ Source_ Glencoe Textbook
What is the same words as ridge?
bridge, hinge
