Webseafloor and recovered long cylinders of sediment. You will read about the sediment, “pull-up” cores of sediment, and view an image of the same sediment as seen under a microscope. This will give you multiple views of the seafloor: from the global scale of Google Earth, down to a 7-cm diameter core, and at the microscopic level. WebQuestion 1. SURVEY. 30 seconds. Q.
