Answer:
True
Explanation:
Mid-ocean ridges are also known as "mid-oceanic ridges." This is regarded as the longest underwater mountain range that are connected across the globe. It's total length is around 65,000 km.
This ridge is formed by "two" tectonic plates that meet at a "divergent boundary" (a linear feature that allows the plates to move apart from each other). The movement of the plates are caused by the rising of "convection currents" (currents in a fluid) in the mantle.
Thus, the answer is true.
