Because of plate tectonics. Because it's 2 plates underwater that are moving apart.
Magma rise up to where the 2 plates are separating to fill in the gap. Seafloor spreading occurs underwater.
The Super Continent was broken apart, in part by sea-floor spreading.Scientists discovered that sea-floor spreading continues to move the continents.Sea-floor spreading can be measured using specialized equipment.
Spreading Of ocean floor
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
Mid ocean ridges are the direct result of sea floor spreading.
yes it does

Sea floor spreading occurs at the mid ocean ridges.
No, sea floor spreading does not happen in a convergent boundary. Sea floor spreading occurs at divergent boundaries, where tectonic plates move away from each other, allowing magma to rise and create new oceanic crust. Convergent boundaries involve tectonic plates colliding, leading to subduction or mountain building.

A deep trench to the mantle
the sea floor is spreading about 3cm every year answers will vary but it is usually around 3cm
Sea floor spreading mean the process by which molten material adds new oceanic crust to the ocean floor
