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.
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
What is the evidence for sea-floor spreading?
at the mid-ocean ridge, molten material rises up from the mantel and spreads out, pushing the older rocks to both sides of the ridge.
How are ocean-floor rocks and sediments evidence of seafloor spreading?
because that there are younger rocks found at ocean ridges than the ones found near deep-sea trenches
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.

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.

What evidence in rocks supports the theory seafloor spreading?
Convergence supports the theory of seafloor spreading. Samples of the deep ocean floor are evidence of seafloor spreading because the basaltic oceanic crust and overlapping sediment become younger as the mid-ocean ridge is approached. Also, the rock that makes up the floor of the ocean is younger than the continents.
