What do scientists use to measure the rate of movement of oceanic plates?
sea-floor spreading
What do scientists now know about earth that would have answered the scientists who rejected wegeners theory?
the sea-floor spreading, and the movement of tectonic plates
What happens when magma in the mantle heats up?
Lots of water will evaporate very fast and the mantle's compositions would harden and solidify to become part of a new sea floor. This is what scientists call 'sea-floor spreading'.
Determining how the sea floor changes over time has given scientists information about the?
formation rate of the ocean crust
What do scientist use to study earths interior?
sea floor spreading :D-3
What can scientists learn about from fossils found in sea floor sediment?
The climate at the time the fossile was preserved. :)
What discovery led scientists to accept Wegeners continental drift hypothesis?
One day while scientists were exploring the sea floor, they discovered sea-floor spreading, thus proving Wegener's hypothesis to be correct.
What did scientists learn when they mapped the ocean floor in the 1800s?
there is a mid-atlantic ridge
What discovery did scientist make when comparing the age of the sea floor to that of the continents?
The scientists realized that the continents were much older, leading them onto the theory of Sea Floor Spreading!
What do scientists use to measure the rate of movement of oceanic plates?
sea-floor spreading
What scientists helped discover the process of the sea floor?
the scientist was Dr. alfred wegener.
What do scientists now know about earth that would have answered the scientists who rejected wegeners theory?
the sea-floor spreading, and the movement of tectonic plates
What do scientists research on submarines?
The sea floor, under water mountains, sea life, under water lava flows, etc.
What did scientist discovere when they analyzed the magnetic bands on the ocean floor?
Scientists found Alternating bands of magnetism.
