Evidence shows that molten material erupts through this valley. The material then hardens to form the rock of the ocean floor.

Pillow lava forms when molten lava erupts underwater and cools rapidly, creating characteristic pillow-like structures. This type of lava is commonly found along mid-ocean ridges, which are areas where sea-floor spreading occurs. The presence of pillow lava on the ocean floor is evidence of volcanic activity associated with sea-floor spreading.

Not really but sea floor sediments thickness increase with increased distance from spreading centers which is good evidence. Other evidence such as magnetic reversals, temperature, dating methods provide the best evidence of seafloor spreading
Magnetic reversals
Magnetic minerals on the ocean floor.
Because of the stripes at the sea floor which are magnetic minerals
Magnetic reversals and sea floor spreading.
Magnetic reversals and sea floor spreading.
Magnetic reversals and sea floor spreading.
The spreading of the sea floor.
seafloor spreading, age of the sea floor and ocean trenches.
Ridges, parallel to the axis of spreading, are formed in the ocean floor as hot lava moves up to fill the gap then cools when it comes in contact with sea water.
