explain how sea-floor spreading provides a way for continents to move
Seafloor spreading is the phenomenon where plates move apart from a spreading centre, where new crust is formed. [ The fact that the plates move apart means that the plates will carry anything which is part of their structure, or is placed upon them...much like a conveyor belt. Many plates have continental landmasses as part of their structure. Consequently, the movement of the plate away from
the spreading centres will also carry the continents away from the spreading centre associated with the plate.
