Answer: The movement of two continents or plates towards each other refers to the convergent boundaries. The process of plate movement was explained by Alfred Wegener in 1912 in the plate tectonic theory.
The movement of the plates on the surface of the earth is a product of the convective currents that come from within the interior of the planet. There exist three types of plate boundaries based on the arrangement of plate and earth structure such as divergent, convergent, and transform boundary.
The convergence can take place between the two continental landmass, oceanic masses and ocean, and continental landmasses. Where the heavier plate collides and sinks into the mantle.
Hence the geologist using the GPS learns that the movement of two landmasses close to each other is due to the consumption of one plate by another.
Orrr, for short; Over millions of years the tectonic plates of these two continents move slowly.
Explanation: hope this helps!
