What is the idea that continents have moved horizontally through the seafloor to their current locations?
seafloor spreading by Harry Hess
Places where the seafloor is forced under continental plates?
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.
What occurs at divergent boundaries and creates new seafloor?
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.
What zone can you find plants roots attached to the seafloor?
The Benthic Zone
What is another name given to a biochemist?

What is the usual amount of seafloor sediments in a given location?
500 to 1000 meters
If One seafloor plate slides under another seafloor plate and begins to melt back into magma the name of this process is?
Subduction
