Which of the following did alfred wegener not use to support his theory of continental drift.

Magnetic surveys of ocean floor reveal.

Among the new findings was the discovery of zebra stripe like magnetic patterns for the rocks of the ocean floor. In this image there is a dusky purple stripe in the center. The discovery adds a key element to the theory of plate tectonics. Ofg has developed proprietary magnetic compensation algorithms to remove vehicle heading and attitude effects from auv and rov based magnetometer surveys.

The same patterns in relation to midoceanic rifts are present in different oceans. Other colored stripes are symmetrical about the dusky purple stripe. The magnetism should reverse as it moves from one segment to the next. Hydrothermal vents and associated mineral seafloor massive sulphide deposits.

Navy and the scripps institution of oceanography tows the first marine magnetometer and finds magnetic striping on the seafloor off the west coast. Magnetic surveys over the ocean floor in the 1960s revealed symmetrical patterns of magnetic bands anomalies parallel to midoceanic rifts figure. The appalachia sierra nevada and rocky mountains all formed due to plate. These magnetic surveys can be used to map or identify.

The patterns reflect the creation and spreading of oceanic crust along the mid oceanic ridges. With reversed polarity the north and south poles are in the opposite position during wwii magnetometers attached to ships to search for submarines located an astonishing feature. These patterns were unlike any seen for continental rocks. The normal and reversed magnetic polarity of seafloor basalts creates a pattern.

Here the plotting compass is simulating a ship using a magnetometer to conduct a magnetic survey of the ocean floor. Coast and geodetic survey ship pioneer in a joint project with the u s. Basalt forming at the ridge crest picks up the existing magnetic polarity. Stripes of normal polarity and reversed polarity alternate across the ocean bottom.

Discovery of magnetic striping on ocean floor. This indicates the type of data that revealed the magnetism of the ocean floor and provided key evidence for the idea of sea floor spreading. This pattern of stripes is like what they discovered on the seafloor. Magnetic surveys of the ocean floor reveal alternating stripes of normal and reversed polarity paralleling the mid atlantic ridge.

Magnetometers in the oceans discovered strange patterns. The oldest ocean crust is only about 150 to 200 million years old.
