Shield volcano.

The rocks are formed by cooling magma, and their specific type depends on the minerals available in the area. The process of magma formation is different at each type of plate boundary, where the tectonic setting is unique. Therefore, the composition of magma differs in each of these settings. As a result, tectonic settings determine the types of volcanoes that form and the types of eruptions that take place. Thinkstock/Comstock/Getty Images. Divergent plate boundaries, caused by the shifting of the Earth's tectonic plates, create igneous rocks as the plates move. The rocks are formed by cooling magma, and their specific type depends on the minerals available in the area. The main type of rock found at divergent plate boundaries is igneous. These rocks are formed when magma cools and becomes solid, either above or below ground. They are rich in elements including silicon, aluminium, sodium, potassium, calcium and iron, and make up about 95 percent of the upper part of the Earth's crust.

Types of volcanoes at divergent boundaries are the boundaries of tectonic plates of earth where two plates will be diverging and drifting apart from each other. The divergent plate boundaries cause the earth surface to ruptures and openings and eventually lead to eruption of magma contents. The volcanoes found in mid-Atlantic ridge, which are caused by divergent plate boundaries, are the best example for such volcanoes. Shield volcano is a type of volcano found at the divergent boundaries. SPREADING CENTER VOLCANOES. The type of volcanoes that are caused by diverging plate boundaries are called as spreading center
