Answer 2

Answer:

A plateau formed by a volcanic eruption.

Explanation:

Lava plateaus are formed by "quiet" (non-eruptive) runny lava during successive eruptions through vents. The resulting sheet lava comes out of  rifts or by volcanic eruptions. Lava flows then cover the original landscape to form a plateau, which may contain lava fields, cinder cones, shield volcanoes and other volcanic landforms.
