Answer:
New crust, sometimes islands/mountains
Explanation:
Divergent boundaries are when two tectonic places are moving away from each other. In the current configuration of Earth, that happens in the ocean.
When plates move away from each other, they leave a gap. That gap is filled with lava that solidifies quickly and forms now crust. If the ocean floor is relatively shallow, and the lava pressure is big enough, that can lead to the formation of new islands, mountains/volcanoes on top of the gap. That's basically how the Galapagos islands were created.
Often, waterfalls form as streams flow from soft rock to hard rock. This happens both laterally (as a stream flows across the earth) and vertically (as the stream drops in a waterfall). In both cases, the soft rock erodes, leaving a hard ledge over which the stream falls
Answer:
Some, but not all, earthquakes are related to volcanoes. ... However, most earthquakes are caused by the interaction of the plates not the movement of magma . Most earthquakes directly beneath a volcano are caused by the movement of magma. The magma exerts pressure on the rocks until it cracks the rock.
