![]() The waves move through the earth, causing the shaking of the ground surface. A divergent plate boundary runs through the Gulf of California in Mexico. Some of this magma crystallizes in the lithosphere, while some is expelled to the ocean floor as lava and forms submarine volcanoes. When a series of mantle plumes exists beneath a large continent, the resulting rifts may align and lead to the formation of a rift valley such as the present-day Great Rift Valley in eastern Africa. However, the Indo-Australian plate, at the centre of which our continent lies, is being pushed to the north-east at about 7cm per year. Examples of oceanic divergent boundaries include the Mid-Atlantic Ridge, the East Pacific Rise, and the Southeast Indian Ridge.ĭo Earthquakes Occur At Divergent Plate Boundaries? These boundaries are important because they are a major source of the earth's volcanic activity and earthquakes. In conclusion, oceanic divergent boundaries are found under the ocean and mark the separation of two tectonic plates. As the plates move apart, the magma that rises up can create volcanoes, and the movement of the plates can also cause earthquakes. Oceanic divergent boundaries are important because they are a major source of the earth's volcanic activity and earthquakes. As these plates move apart, magma rises up and forms new crust, creating the Southeast Indian Ridge. This boundary marks the separation of the Australian Plate and the Antarctic Plate. As these plates move apart, magma rises up and forms new crust, creating the East Pacific Rise.Ī third example is the Southeast Indian Ridge, located in the Indian Ocean. This boundary marks the separation of the Nazca Plate and the Pacific Plate. As these plates move apart, magma rises up and creates new crust, forming the ridge.Īnother example of an oceanic divergent boundary is the East Pacific Rise, located off the west coast of South America. This ridge is formed by the separation of the North American Plate and the Eurasian Plate. One of the most well-known is the Mid-Atlantic Ridge, which runs down the center of the Atlantic Ocean. ![]() There are several examples of oceanic divergent boundaries around the world. ![]() This process is known as sea-floor spreading. As the magma cools, it solidifies and becomes part of the earth's crust. This type of boundary is found under the ocean, where magma from the mantle rises up and creates new crust. An oceanic divergent boundary is a type of tectonic boundary where two plates are moving apart from each other. ![]()
