What is produced when magma rises at a divergent boundary?

When magma rises at a divergent boundary, it results in the process known as seafloor spreading. This occurs at tectonic plates that are moving away from each other, allowing magma from the mantle to flow up to the surface. As the magma erupts and cools, it solidifies into new crust, forming new oceanic lithosphere.

Seafloor spreading can create mid-ocean ridges, which are underwater mountain ranges formed by the accumulation of this newly formed crust. It is a fundamental part of the geological processes that lead to the expansion of ocean basins. The constant upwelling of magma and the subsequent cooling also contribute to the formation of new igneous rocks, but the specific process being described is seafloor spreading itself.

While mountain ranges and earthquakes can occur near divergent boundaries, they are not direct products of the rising magma at those locations. Mountain ranges are typically associated with convergent boundaries, where tectonic plates collide. Earthquakes can occur due to movements of tectonic plates, but they are not produced by the magma rising directly. The formation of new igneous rocks is an outcome of the cooling of magma, but it is the process of seafloor spreading that specifically describes the rise of
