What erupts on the ocean floor?
Three types of lava flows are common on the sea floor: pillow lava, lobate lava, and sheet lava. Scientists believe the main difference between the shapes of submarine lava results from how fast the lava erupts from deep-sea fissures and how steep the seafloor is that the lava travels over.
Are there any extinct volcanoes on the East Coast?
No. The geologic forces that generated volcanoes in the eastern United States millions of years ago no longer exist. Through plate tectonics, the eastern U.S. has been isolated from the global tectonic features (tectonic plate boundaries and hot spots in the mantle), that cause volcanic activity.
What volcano erupted in the Caribbean?
