Answer: The majority of lava extruded at divergent plate boundaries (mid-ocean ridges).

Explanation: Hot mantle rock rises into space at divergent plate boundaries. As the hot mantle rock convects upward it rises higher in the mantle. This result in the rock having lower pressure and consequently allowing the rock to melt. Lava then erupts through long cracks in the ground.
