Why Were Magnetic Patterns On The Ocean Floor Puzzling

All rocks were magnetic.

Why were magnetic patterns on the ocean floor puzzling.

When the earth s magnetic field reverses a new stripe with the new polarity begins. In short it doesn t the spreading of the sea floor comes from magma oozing up between the cracks between continental plates as lava. In 150 million years. Evidence supporting the idea of sea floor spreading what finally confirmed wegener s hypothesis of continental drift.

This lava subsequently cools rapidly and forms solid rock. 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. Name the location where deep ocean trenches form. 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.

Tracks of continents plowing through the ocean floor rock. Describe how tectonic plate motion occurs. No rocks were magnetic. Why were magnetic patterns found on the ocean floor puzzling.

Describe what a ridge is. They did not show alternating bands of normal and reversed polarity. Identify the most conclusive proof of continental drift. Because they showed alternating bands of normal and reversed polarity why was the study of paleomagnetism in the study of plate tectonics.

What do you call the process that forms and moves new oceanic crust. Explain why magnetic patterns on the ocean floor were puzzling. 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. Magnetic patterns on the ocean floor were puzzling because they.

As long as the magnetic field remains constant the polarity stripe widens. Explain how sediment that is closer to a mid ocean ridge compares to sediment that is farther away. Why were magnetic patterns on the ocean floor puzzling. Why were magnetic patterns found on the ocean floor puzzling.

North america and eurasia were formed when a rift separated the continent of.
