Magnetic striping magnetic minerals are found in rocks.
Magnetic stripes on sea floor.
By using the magnetometer the magnetic polarity will be shown through a timescale that contains the normal and a reverse polarity.
Among the new findings was the discovery of zebra stripe like magnetic patterns for the rocks of the ocean floor.
Basalt the once molten rock that makes up most new oceanic crust is a fairly magnetic substance and scientists began using magnetometers to measure the magnetism of the ocean floor in the 1950s.
Magnetic striping of the sea floor after mid ocean ridges and trenches were discovered more evidence was discovered that helped to support the theory that the continents had moved around.
When scientists studied patterns in the rocks of the ocean floor they found more support for sea floor spreading.
The discovery of magnetic stripes on the seafloor in the 1950s validated the plate tectonics theory for the geological community.
In the 20th century the magnetic survey was conducted in the mid ocean ridge in order to investigate evidence of sea floor spreading.
These two things were the magnetic striping on the ocean floor and the age of seafloor rocks.
Surprisingly earth s magnetic poles have reversed themselves many times during earth s history.
Evidence from magnetic stripes.
These patterns were unlike any seen for continental rocks.
Magnetic stripes and isotopic clocks oceanographic exploration in the 1950s led to a much better understanding of the ocean floor.
