If a piece of sea floor has moved 50 km in 5 million years what is the yearly rate of sea-floor motion?
To calculate the yearly rate of sea-floor motion, we divide the total distance moved (50 km) by the total time taken (5 million years). 50 km / 5,000,000 years = 0.00001 km per year Therefore, the yearly rate of sea-floor motion is 0.00001 km/year.
What motion of the sea floor causes the mid Atlantic ridge rift valley?
The motion of the sea floor at the mid-Atlantic ridge rift valley is primarily caused by seafloor spreading. This process occurs when new oceanic crust is formed as magma rises up and solidifies at mid-ocean ridges, pushing the existing seafloor apart. Over time, this spreading creates a rift valley at the mid-Atlantic ridge as the tectonic plates move away from each other.
Which are younger old seafloor rocks or old continental rocks?
Old sea floor rocks are much younger than old continental rocks! This is because the oceanic lithospheric plate forming the seafloor tends to be recycled at places known as subduction zones where it is forced below less dense (commonly continental) lithosphere. As such the oldest continental rocks tend to be 2-3 billion years old whereas oceanic crust neve tends to be more than a few hundred million years old.
Magnetic stripes on the seafloor are caused in part by?
symmetrical spreading of the ocean floor at mid-ocean ridges, where molten material rises to create new seafloor. As this material cools and solidifies, it records the Earth's magnetic field at the time, creating magnetic stripes on the seafloor. This phenomenon provides evidence for seafloor spreading and plate tectonics.
Is there evidence that seafloor-spreading?
Yes, there is evidence supporting seafloor spreading, including magnetic striping patterns on the ocean floor, the age progression of seafloor away from mid-ocean ridges, and the presence of hydrothermal vents along mid-ocean ridges that release magma from the Earth's mantle.

What is the age of the oldest seafloor?
The sea floor is older than 200 million years. It has been recycled by plate tectonics. Very old rocks have survived.

What is seafloor mining?
Mining on the sea floor, are you dumb?
How old is the sea floor?
The age of the sea floor varies, with the youngest being less than 200,000 years old and the oldest being over 200 million years old. This variation is due to the process of seafloor spreading at mid-ocean ridges and the subduction of older seafloor at deep-sea trenches.
Where do you find young seafloor?
in the depths of the oceanic crust floor.

What motion of the sea floor is responsible for the formation of the mid Atlantic ridges rift valley?
According to scientists, the process associated with seafloor spreading is responsible for the formation of the mid Atlantic ridges rift valley.
What motion of the sea floor causes the mid Atlantic ridge rift valley?
The motion of the sea floor at the mid-Atlantic ridge rift valley is primarily caused by seafloor spreading. This process occurs when new oceanic crust is formed as magma rises up and solidifies at mid-ocean ridges, pushing the existing seafloor apart. Over time, this spreading creates a rift valley at the mid-Atlantic ridge as the tectonic plates move away from each other.
The bottom of the ocean is called?
The bottom of an ocean is typically called the seafloor. Although the seafloor can have variant geographical features such as mountains or volcanos, a normal, and flat terrain is called the seafloor.
What three pieces of evidence for Wegener's theory came from the sea floor?
seafloor spreading, age of the sea floor and ocean trenches.
