Explain how the positions of earthquakes (both on the surface and in the interior), seafloor paleomagnetic data and GPS data, support the plate tectonics hypothesis.

By providing information about tectonic plates.

Explanation:

The location or position of earthquake provide information about the presence of tectonic plates. The sliding of plates over one another is the main and single cause of earthquake. Continental drift is also the consequence of the movement of the plates which divides a single large continent into seven small continents so we can conclude that the location of earthquake provides evidences that supports the plate tectonics hypothesis.

places of higher salinity. there are parts of the ocean where hardly any rain falls but warm dry winds cause lots of evaporation. this evaporation removes water – when water vapour rises into the atmosphere, it leaves the salt behind, so the salinity of the seawater increases. this causes the seawater to become denser.
