seafloor spreading by Harry Hess
The region where the seafloor is forced beneath the continental plate is called a subduction zone. When the seafloor descends down it produces a deep-ocean trench.

At divergent plate boundaries the spreading of the tectonic plates results in the reduced pressure of the underlying magma. As the spreading continues, lava fills in the area of spreading and cools, becoming the newest addition to the seafloor. This process occurs at a steady rate ranging from a few centimeters to several centimeters of new sea floor each year. However, at a different location opposite the newly formed seafloor are convergent plate boundaries where land and seafloor is destroyed to make room for new seafloor.
The Benthic Zone
The thicker the slab of seafloor, the more material it contains, leading to a greater weight. This weight is influenced by the density of the rock forming the seafloor. Thicker slabs of seafloor would have more mass and therefore weigh more than thinner slabs.
The amount of seafloor sediments can vary widely depending on location. Generally, it ranges from a few centimeters to several kilometers thick. Factors such as proximity to land, ocean currents, and sediment sources influence the accumulation of sediments on the seafloor.

They proved that the seafloor was spreading.
whatis the flat part of the seafloor called?
The observation of the alternating magnetic stripes on the seafloor was instrumental in formulating the hypothesis of seafloor spreading.

Yes. Seafloor spreading is the term given to the creation of new seafloor at divergent boundaries. At a divergent boundary, two oceanic plates move apart, which obviously means that something must then surface to fill the void. This is where the magma rises from the Earth's interior and cools to become seafloor. On the other end, at convergent boundaries, the old seafloor is forced under the continental plates, where it is recycled back into the Earth's magma supply.
