Question

Quizplus · Accepted Answer

Ultramafic rocks form at the upper mantle, which is located below the Earth's crust. These rocks are composed primarily of dark, heavy minerals like olivine and pyroxene and are associated with the mantle portion of the Earth's lithosphere. They are not typically found at the Earth's surface or in volcanoes, and while they may be involved in convergent boundary processes, they do not form specifically at these boundaries.
