Is the analysis of seafoor sediments evidence of 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
What types of volcanoes are formed at spreading centers?
Volcanoes at spreading centers is referred to as spreading center volcanism. This usually takes place on mid-oceanic ridges where the plates diverge.
Explain the relationship between trenches and seafloor spreading?
1. New sea-floor is created by the upwelling of magma at mid-ocean spreading centers; old ocean floor is destroyed by subduction at deep sea trenches. 2. The area is a subduction zone. Magma from underground comes up and destroys that crust. That crust is then recycled and the magma cools and hardens. That creates new land, that creates the trenches. Seafloor spreading is in the ocean and happens with convection currents. That is the relationship between. 3. As new seafloor is formed at mid-ocean ridges, the old seafloor is pushed down into trenches at subduction zones.
Divergent Boundaries are also called?
Spreading centers.
What are the spreading centers?
It is a center at the bottom of the ocean that occurs at mid-ocean ridges
Where are most seafloor spreading centers located?
It is the mid-ocean ridges.
Ocean ridges generally are located where?
At spreading centers.
Where is the greatest sediment thickness on the ocean floor?
Near the trenches, or in the seafloor furthest away from spreading centers.
Ocean crust is formed were in the ocean?
Ocean crust is formed at seafloor spreading centers. One example of this is the Mid-Atlantic ridge.
Where are most hydrothermal vents found?
Hydrothermal vents are found along seafloor spreading centers on the bottom of the oceans.
Have been found in waters of hydrothermal vents?
hydrothermal vents are found in the deep zone

What boundary type is sea floor spreading?
These ridges are spreading centers or divergent plate boundaries
Divergent Boundaries are also called?
Spreading centers.
