the magnetic patterns from seafloor data

The patterns reflect the creation and spreading of oceanic crust along the mid-oceanic ridges. Always run perpendicular to the equator.

This creates a symmetrical pattern of magnetic stripes of opposite polarity on either side of mid-ocean ridges.

. Are indicators of past and future earthquake sites. After digesting the data in this report along with other information two young British geologists Frederick Vine and Drummond Matthews and also Lawrence Morley of the. The magnetic patterns from seafloor data.

The lava erupted on the seafloor is the most magnetic because it has the smallestcrystals. When these magnetic patterns were mapped over a wide region the ocean floor showed a zebra-like pattern. Mattox 1992 Based on the pattern and spacing of the oceanic magnetic stripes and the inferred motion of the plates the age of the ocean floor can be determined.

The crystals have no time to grow any larger because the cold nearfreezing seawater at the bottom of the ocean makes the lavas cool very fastThe dikes which are the frozen conduits or pathways that supplied the magmato the seafloor are less magnetic because they don t cool as fast as. These surveys revealed a series of invisible magnetic stripes of normal and reversed polarity in the sea floor like that shown in the figure below. The magnetic patterns from seafloor data were created by magnetite in lava flows.

At the mid-ocean ridge spreading axis these flips in the direction of the Earths magnetic field are recorded in the magnetization of the lava. Explains how magnetic polarity frozen into seafloor basalts reveals evidence for the creation of new seafloor at mid-ocean ridges. C are indicators of past and future earthquake sites.

The pattern of magnetic strips shows that the seafloor is expanding at mid-ocean ridges. D have no one explanation accepted by scientists. A were created by magnetite in lava flows.

This is their best hypothesis. 6 hours agoThis cycle of creation and destruction takes about every 180 million years the age of the oldest seafloor. The magnetic patterns from seafloor data.

The crusts magnetic record. Age of Sea Floor. Were created by magnetite in lava flows.

Magnetic Patterns on the Sea Floor. E always run perpendicular to the equator. Are caused by hot spots.

Have no one explanation accepted by scientists. Are indicators of past and future earthquake sites. Müller and others 1997.

When seafloor lava solidifies at the seafloor its magnetic crystals. Have no one explanation accepted by scientists. In the figure below the age of the ocean floor is depicted.

The patterns reflect the creation and spreading of oceanic crust along the mid-oceanic ridges. The striped magnetic pattern develops because as oceanic crust pulls apart magma rises to the surface at mid-ocean ridges and spills out to create new bands of ocean floor. Are indicators of past and future earthquake sites.

Always run perpendicular to the equator. B are caused by hot spots. Have no one explanation accepted by scientists.

Are caused by hot spots. Always run perpendicular to the equator. Why do magnetic stripes on the ocean floor form a symmetrical pattern on either side of mid-ocean ridges.

Naval Oceanographic Office prepared a report summarizing available information on the magnetic stripes mapped for the volcanic rocks making up the ocean floor. Were created by magnetite in fissure flows. This indicates how strong in your memory this concept is.

Basalt forming at the ridge crest picks up the existing magnetic polarity. Later after the planets magnetic field flips again the. In 1962 scientists of the US.

Practice Magnetic Evidence for Seafloor Spreading. Always run perpendicular to the equator. The magnetic patterns from seafloor data were created by magnetite in lava flows.

Are indicators of past and future earthquake sites. This creates a symmetrical pattern of magnetic stripes of opposite polarity on either side of mid-ocean ridges. The magnetic patterns from seafloor data were created by magnetite in lava flows.

The magnetic pattern from seafloor data recorded off the coast of Vancouver and Washington State a. The figure below shows the observed magnetic pattern along the mid-Atlantic Ridge south of Iceland. How magnetic patterns develop on the seafloor.

Seafloor lavas have built-in magnetic clocks that reveal their age. Are caused by hot spots.
