Why Were Magnetic Patterns On The Ocean Floor Puzzling

Tracks of continents plowing through the ocean floor rock.

Why were magnetic patterns on the ocean floor puzzling.

Because they showed alternating bands of normal and reversed polarity why was the study of paleomagnetism in the study of plate tectonics. As long as the magnetic field remains constant the polarity stripe widens. Magnetic patterns on the ocean floor were puzzling because they showed altering bands on of normal and reversed polarity wegeners hypothesis of continental drift was finally confirmed by. Plate tectonics and reversals of the earth s magnetic field are responsible for the magnetic stripes found on the ocean floor.

Describe how tectonic plate motion occurs. Magnetic patterns on the ocean floor were puzzling because they showed alternating bands of normal and reversed polarity wegner s hypothesis of continental drift was finally confirmed by evidence supporting the idea of sea floor spreading. Why were magnetic patterns found on the ocean floor puzzling. Evidence supporting the idea of sea floor spreading what finally confirmed wegener s hypothesis of continental drift.

All rocks were magnetic. They showed alternating bands of normal and reversed polarity. When magma flows out of a mid ocean ridge small magnetic minerals in the magma align themselves to point in the direction of the earth s current magnetic north. What do you call the process that forms and moves new oceanic crust.

Describe what a ridge is. When the earth s magnetic field reverses a new stripe with the new polarity begins. They did not show alternating bands of normal and reversed polarity. Such magnetic patterns led to recognition of the occurrence of sea floor spreading and they remain some of the strongest evidence for the theory of plate tectonics.

Why were magnetic patterns found on the ocean floor puzzling. Explain how sediment that is closer to a mid ocean ridge compares to sediment that is farther away. In 150 million years. North america and eurasia were formed when a rift separated the continent of.

Why were magnetic patterns on the ocean floor puzzling. Explain why magnetic patterns on the ocean floor were puzzling. This lava subsequently cools rapidly and forms solid rock. Identify the most conclusive proof of continental drift.

No rocks were magnetic.
