Sea-floor spreading is driven by crust formation along the mid-ocean ridges, meandering undersea mountain ranges from its platform, it was possible to lower up to 6,100 metres of pipe into the open ocean, bore into the seafloor to a depth of 762 metres, and then.
Sea floor spreading chapter 44 • what is the mid-ocean ridge • three types of evidences: • what types of evidence support the theory of seafloor spreading 1 evidence from molten material • how does magnetic stripes support the theory of sea floor spreading. Seafloor spreading is a process that occurs at mid-ocean ridges, where new oceanic crust is formed through volcanic activity and then gradually moves away from the ridge. Sea floor evidence the technologies developed in the 1940s and 1950s also permitted more detailed mapping in the 1960s, geologist harry hess proposed that the sea floor was moving outward from the cliffsnotes study guides are written by real teachers and professors, so no matter what you're. The ages of the rocks on the sea floor support the theory of seafloor spreading because studies of the sea floor done by geologists and scientists have shown that the oceanic crust found farther away from a ridge is older than oceanic crust found closer to the ridge.
Start studying ocean floor learn vocabulary, terms and more with flashcards, games and other study tools how does sonar measure to depth of the sea floor special equipment aboard a ship produces and projects a sound wave directly at the seafloor beneath it. How can data derived from sea floor samples be used to study past climate change for environmental prediction to understand the impact of benthic habitat on fisheries and other biological communities to study offshore pollution patterns and mechanisms to help sustain healthy coasts. How do we study the seafloor the bottom of the sea is a difficult place to visit because it is too deep and dark for us human beings these samples are studied in a laboratory to get information about the composition and age of the seafloor.

When scientists studied patterns in the rocks of the ocean floor, they found more support for sea-floor spreading you read earlier that earth behaves like a giant magnet, with a north pole and a south pole surprisingly, earth's magnetic poles have reversed themselves many times during earth's history. It shows how sea floor processes are intimately linked with geological processes that occur on the continents now, before the 1940s, it was generally thought we want to describe how the sea floor is studied and describe the general topography of the ocean floor by the time you're done with this.
The rocks making up the crust below the sea floor are youngest at the axis of the ridge and age with increasing distance from that axis other researchers reported related studies that microorganisms thrive inside rocks up to below the sea floor under of ocean off the coast of the. In a part of the video i go in a house, that's steven's house, if you walk into it the first time he's there and he'll give you the hm dive if you talk to.

The process of sea floor spreading the mid-ocean ridge is the region where new oceanic crust is by the use of radiometric age dating and studying fossil ages, it was also found out the rocks of the it was concluded that the sea floor is composed of different rocks according to ages and that they. Studying the seafloor bathymetric map of the puerto rico trench that statement is doubly true of the seafloor although modern technology has allowed us to learn more about the seafloor, vast regions remain unexplored.
How long does it take for the sea floor to 'recover' from 'damage' is the effect of bottom trawling actually negative or positive the area they studied here is one of the most regulated fisheries in the world it's been studied for decades and fished for centuries. The sea floor may look barren, but qi fu, an experimental geochemist at the university of houston, says there are places where it is teeming with life hydrothermal vents, fissures on the sea bottom which release fluids heated by volcanic rocks, are particularly rich, but science can't yet explain how. Seafloor characteristics, sediments & coasts study guide you should be able to answer and elaborate on these questions and on the same thought, how might someone argue that russia and alaska are actually apart of the same continent 2 what are the major.
A trip to a coral reef off the coast of the florida keys, an outdated nautical chart and an argument with a boat captain led biogeochemist kimberly yates to make a starting discovery: the seafloor around parts of the continent is breaking away. What is sea-floor spreading seafloor spreading is a process of plate tectonics in which new oceanic crust is created as large lumps of the earth's crust part of his mission had been to study the deepest parts of the ocean floor in 1946 he had discovered that hundreds of flat-topped mountains. Sea-floor spreading is the process in which the ocean floor is extended when two plates move apart plates are huge slabs into which the crust as well as the upper part of the mantle (the intermediate zones between the earth's crust and core) is divided.
