There re 2 ways 1) pick up material from the sea floor and remove all the rocks and sand and study what is left 2) pick up the material from the sea floor and remove all the organic material and study what is left. The seafloor is eroding faster than scientists thought by 2100 sea floor erosion could increase water depths by two while the study does not look. Sea floor age maps have been proven correct by the age dates calculated from hundreds of rock samples gathered from the ocean floor seismic studies more proof for sea floor spreading comes from seismic studies indicating that earthquakes occur along the rift valley of a midoceanic ridge and the cross‐cutting fractures that offset it. The seafloor rocks on the mid-atlantic ridge were only a few million years old, while those closest to the continents were about 200 million years old it was determined that the seafloor basalt is youngest at mid-ocean ridges and oldest adjacent to continents seafloor spreading had been proved harry hess was right and alfred wegener was.

Sonar sonar can be used to measure how deep the seafloor are a device records the time it takes sound waves to travel from the surface to the sea floor and back. The floor of the mediterranean is not well studied since much of it is covered by miles-deep sediment, making exploring impossible so instead of visiting the crust, researchers measured what they call magnetic anomalies—stripes of differing magnetic orientations recorded in the crust—to examine the sea floor. Continental drift, sea floor spreading and plate tectonics alfred wegner was a german meteorologist in the early 1900s who studied ancient climates. Unit 5, lesson 3 -- geologic change over time they can look at tree rings, they can study long cylinders of sea-floor sediment taken from the ocean floor. Ocean-floor sediments sediment on the turbidity currents provide additional transport out to the deep sea the resuspension of the sediment into the. Unlike mapping the land, we can’t measure the landscape of the sea floor directly from satellites using radar, because sea water blocks those radio waves.

Hess proposes sea-floor spreading 1960 been to study the deepest parts of the ocean floor the movement of the continents was a result of sea-floor spreading. There are three kinds of sea floor sediment: terrigenous, pelagic, and hydrogenous terrigenous sediment is derived from land and usually deposited on the continental shelf, continental rise, and abyssal plain it is further contoured by strong currents along the continental rise. Home » faq on earth sciences » geology » how do we know the age of the seafloor faq on earth sciences natural when scientists studied the magnetic properties.

Exploring the deep ocean floor: study) used alvin to dive on a segment of the mid-atlantic ridge in an attempt to make the first direct observation of seafloor. Chapter 18 - the sea floor 18-1 chapter 18 the sea floor multiple choice questions 1 the study of _____ rocks, sediment, and topography provided most of the information that led to the concept of plate tectonics. Describe how the sea floor is studied water is 35 kilometers high and exerts a pressure hundreds of times greater than atmospheric pressure on earth.
