Answer: Igneous
Explanation:
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. More than 700 types of igneous rock have been identified.
Most rocks formed at divergent boundaries are categorized as malefic igneous rocks, which are dark-coloured due to their high magnesium and iron content. This category includes basalt, gabbro and peridotites, which are often found at these boundaries.
