which evidence from the sea floor shows that tectonic plates move ?

AThe sea floor is much older than any of the continents.
BThe sea floor is youngest near a mid-ocean ridge and older farther away.
CMid-Ocean ridges circle Eqarth like seams in a baseball
DThe sea floor is thinner than continental crust.

"The sea floor is youngest near a mid-ocean ridge and older farther away" is the one evidence from the sea floor among the following choices given in the question which shows that tectonic plates move.

Answer:

b) The seafloor is youngest near a mid-ocean ridge and older farther away.

Explanation:

The evidence that Alfred Wegener gave in his plate tectonic theory, was based on the fact that the seafloor is spreading and this was highlighted by Harry Hess in his geodetic survey of the ocean basins and his findings.

Which shows that seafloor spreads in both direction based on the studies of the paleomagnetism and the formation of the rocks that differed in terms of the ages.

He found that old rocks are found near the continental shelves and the newer rocks are located near to the mid-oceanic ridges as the rocks in the ridges are formed by the spreading of the lavas on both sides of the ridges that creates and reverse magnetic properties of the rocks that aligned to the northern and the southern faced sides.
