Answer:
a land that is raised and flat
Step-by-step explanation:
Typically, plateau was formed by either Volcanic activity or a Tectonic activity.
Collection of Eruptions from Volcanoes could gradually increase the land elevation overtime, forming the raised and flat structure on the land. Similar process could also be found from the upward movement in the Earth's crust when tectonic plates were colliding with one another.
Currently, Geologist predict that Plateaus make up almost 1/3 of the Earth's surface. They can be found in all continents across the world.
