it makes mid-oceanic ridges
Sea floor spreading
There are two places that divergent boundaries occur. Under the sea where magma pushes up to form lava ridges and at the divergence at the Red Sea near the Suez canal.
Seafloor spreading occurs at divergent plate boundaries under the ocean.
the most famous divergent fault is the san Andreas faultEDIT: Actually, the San Andreas Fault is a Transform boundary. A Transform Boundary is when two plates are rubbing against each other while going opposite ways. A Divergent Boundary is when two plates move away from each other. Scientists have not pinpointed and named a Divergent Boundary but Divergent Boundaries usually occur under water in the sea, also called Sea Floor Spreading.
plates moving together
A rift zone on land, a mid ocean ridge under the ocean.
Sea floor spreading
it is a tsunami or an under water volcano
divergent boundaries are under the ground earth quakes

Hi when to plates pul apart under the ocean its called tectonic plate drift or contenetial drift.This allows countries to moves centimetres evvey year in any direction the plate travels.sometimes the plates rub and can cause earthquakes ,volcanos or tsunamis.

Three main structures form by convergent boundaries. There are three types of convergent boundaries, oceanic-oceanic, oceanic-continental, and continental- continental. Oceanic to oceanic boundaries form volcanic islands, because the two plates come together, one crust goes under, the other forms a mountain, and the lava from the crust that went under the other one goes through the mountain, making it a volcano. Oceanic- continental convergent boundaries form volcanoes, the continental crust form the mountain, the oceanice goes under and makes the lava that goes up through the mountain and makes a volcano. continental to continental boundaries form mountains. since both crusts are of the same density, they both shoot up and form a mountain.
I believe this is Iceland, however it is not necessarily a hotspot as such, as notable hotspots do not occur on plate boundaries. An example of a hotspot is under Hawaii and neighbouring islands.
