Answer:
Evidence that supports Hess' theory of seafloor spreading are:
-the age of different rocks on Earth's surface
-pillow-shaped rocks found in the sea
Explanation:
Seafloor spreading is a geological process that states that seafloor structures would originate from mantle materials through the action of convection currents. Emerging in the dorsal zones, magma - coming from the mantle - would solidify laterally, promoting the distance between the oceanic and dorsal bottom, opening a kind of crack in its crest. However, this slit created in the dorsal crest by distancing the anterior material would again be filled by the magma derived from the interior of the crust, which, when solidified, would lead to further distalation of the dorsal sides and so on.
The idea that the ocean floor moves as it expands from a central axis was proposed by Harry Hess of Princeton University in the 1960s.
