Question

Define sea floor spreading.
O the concept that the continents have moved about over the Earth's surface.
the process by which new lithosphere is created at spreading ridges as plates of
oceanic lithosphere move apart.
O the deflection of ocean waves as they approach shore.
a continuous, directed movement of sea water from lower regions by varying
temperatures and salinity which affect the density of the water, which in turn,
defines each oceanic region

Expert Solution

Step 1

The molten material found beneath the earth surface is termed magma. The mobile plate is the plate that divides the earth lithosphere. The plates are floating above the partially melted semi-plastic region is called Asthenosphere. The movement of several major and minor plates of the earth lithosphere is called plate tectonics. The internal heat source of earth driven convection current is the chief cause for the movement of earth lithospheric plates.
