WebApr 1, 2010 · Scientists use the magnetic polarity of the sea floor to determine the age. Very little of the sea floor is older than 150 million years. This is because the oldest sea floor is subducted under other plates and replaces by new surfaces. The tectonic plates are constantly in motion and new surfaces are always being created. WebFor example, take the Great Rift Valley in Africa. The African, Arabian, and Indian plates are moving. The land of Africa east of the Great Rift Valley is separating from the rest of Africa. Eventually (a few million years), a new plate will be created, being the land that has separated. ( 6 votes)

WebAnswer (1 of 2): Plate motion Euler’s contributions In the 18th century, Swiss mathematician Leonhard Euler showed that the movement of a rigid body across the surface of a sphere can be described as a rotation around an axis that goes through the centre of the sphere, known as the axis of rota...
WebThen they can track the movement every day and over a year they can map exactly how fast it is moving, and in which directions. Scientists do this along tectonic plates all over the world so we can track plate movement (which often correlates to earthquake monitoring because earthquakes often occur along the edges of tectonic plates).
