What is the process in which the sea floor separates and moves in opposite direction is known as?
The process in which the sea floor separates and moves in opposite directions is known as seafloor spreading. This occurs at mid-ocean ridges, where tectonic plates move apart, allowing magma to rise from the mantle and create new oceanic crust.
What happens to the ocean floor the farther the oceanic lithosphere is from a mid ocean ridge?
As the oceanic lithosphere moves away from a mid-ocean ridge, it cools and thickens. This process causes the ocean floor to become older and denser, resulting in its gradual subsidence. The farther it gets from the ridge, the deeper the ocean floor becomes due to the increased thickness and weight of the lithosphere.
How do strip 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.
What on the ocean floor is evidence that earths magnetic field changes?
Evidence that Earth's magnetic field changes can be found in the alignment of magnetic minerals in rocks on the ocean floor. As magma solidifies into new rock, the magnetic minerals within it align with the current magnetic field direction. By studying the alignment of these minerals in rocks of different ages along the ocean floor, scientists can track changes in the Earth's magnetic field over time.
What are pieces of evidence of sea floor spreading?
Pieces of evidence for sea floor spreading include the presence of mid-ocean ridges where new crust is formed, symmetric magnetic striping on either side of mid-ocean ridges, age dating of oceanic crust that shows it gets older as it moves away from ridges, and the discovery of pillow basalts and other volcanic rocks on the ocean floor.
What moves the ocean floor?
the tectonic plates under the earths surface

A portion of the ocean floor moves rapidly downward what type of wave would you expect?
tsunami
What causes water near the ocean floor to move from poles to equator?
Water near the ocean floor moves from the poles to the equator primarily due to thermohaline circulation, which is driven by differences in temperature and salinity. Cold, dense water at the poles sinks and flows towards the equator, while warmer, less dense water rises and moves poleward at the surface. This global conveyor belt of ocean currents plays a crucial role in regulating climate and distributing heat across the planet. Additionally, the Coriolis effect influences the direction of these currents as they move along the ocean floor.

Is mid-ocean ridge is how the direction of sea-floor spreading?
It spreads away form the ridges
What is it called when the sea floor spreads out from both sides of a mid ocean ridge and moves towards continents?
sea floor spreading or divergent boudary
Use the words sea floor spreading and mid ocean ridges in a complete sentence?
Mid ocean ridges are the direct result of sea floor spreading.
In which location would an ocean ridge?
The mid-ocean ridge is almost in all of the oceans
What happens to the ocean floor the farther the oceanic lithosphere is from a mid ocean ridge?

The farther it gets from the ridge, the deeper the ocean floor becomes due to the increased thickness and weight of the lithosphere.
What is the topography of the ocean floor?
