As new seafloor rocks are formed, they record the direction of the earth's changing magnetic field.
b. false
As seafloor converges, one plate may also flow underneath the other causing earthquakes, forming volcanoes, or developing deep ocean trenches. wherein plates diverge from every other, molten magma flows upward between the plates, forming mid-ocean ridges, underwater volcanoes, hydrothermal vents, and new ocean ground crust
Every location of the sea floor has ordinary functions consisting of commonplace sediment composition, standard topography, the salinity of water layers above it, marine existence, the magnetic path of rocks, and sedimentation. some features of the seabed consist of flat abyssal plains, mid-ocean ridges, deep trenches, and hydrothermal vents.
However, satellites can use radar to degree the peak of the sea floor very as it should be. And if there are sufficient measurements to subtract the results of waves and tides, satellites can definitely degree bumps and dips inside the sea surface that end result from the underlying panorama of the sea ground.
