Iceland is an example of a country undergoing a continental divergent boundary. The Mid-Atlantic Ridge divides Iceland and is the boundary between the North American and Eurasian tectonic plates. When divergent boundaries occur under continental plates, they form a rift valley.
Considering this, what happens at a divergent plate boundary?
Divergent boundaries in the middle of the ocean contribute to seafloor spreading. As plates made of oceanic crust pull apart, a crack in the ocean floor appears. Magma then oozes up from the mantle to fill in the space between the plates, forming a raised ridge called a mid-ocean ridge.
What are the characteristics of divergent boundaries?
Effects that are found at a divergent boundary between oceanic plates include: a submarine mountain range such as the Mid-Atlantic Ridge; volcanic activity in the form of fissure eruptions; shallow earthquake activity; creation of new seafloor and a widening ocean basin.
