What is the evidence that sea-floor spreading takes place in mid-ocean ridges?

The mid-ocean ridges are the buoyant, hot solidified magma that has formed from the decompressed, melting rock of the upper mantle where the oceanic plates are separating.

How do the ages of the rocks on the seafloor support the theory of seafloor spreading?
The ages of the rocks become older the farther the way they are from the ridges. The closer they are the younger it is. This leaves evidence to the seafloor spreading theory.
What process forms new seafloor?
Seafloor spreading at midoceanic ridges.
How are magnetic patterns in sea floor rock evidence of seafloor spreading?
Magnetic alignment of rocks, in alternating strips that run parallel to ridges, indicates reversals in Earth's magnetic field and provides further evidence of seafloor spreading.
How do the ages of the rocks on the ocean floor support the theory of seafloor spreading?
The ages of the rocks become older the farther the way they are from the ridges. The closer they are the younger it is. This leaves evidence to the seafloor spreading theory.
How do the ages of rock on the ocean floor support the theory of seafloor spreading?
The ages of the rocks become older the farther the way they are from the ridges. The closer they are the younger it is. This leaves evidence to the seafloor spreading theory.
What is the seafloor spreading apart at?
mid-ocean ridges
Where is the place where seafloor spreading occur?
Mid-oceanic ridges
Where does seafloor spreading take place?
Mid-Ocean ridges.
Where are most seafloor spreading centers located?
It is the mid-ocean ridges.
What is the primary evidence that forms the basis of seafloor spreading?
The magnetic properties of rocks along the mid-oceanic ridges change alignment in a symmetrical manner.
Explain how ocean-floor rocks and sediments are evidence of seafloor spreading?
The seafloor rocks vary in different places. Rock samples near ocean ridges are younger than rocks at deep sea trenches
A typical rate of seafloor spreading in the Atlantic Ocean?
The typical rates of seafloor spreading is 5 centimeters per year. Seafloor spreading is a process that occurs at mid ocean ridges.
