As Tanya walked, she could feel the effects of the elevation on her breathing. It was hard to catch her breath. But the ground was flat, level, and easy to walk on—not like the steep peaks she navigated yesterday. Which landform is Tanya most likely hiking on?

A plateau is a broad, elevated area of land with a relatively flat surface. Tanya feels the effects of high elevation, but the ground is level rather than steep, so a plateau fits best. Plains are generally flat but not notably elevated, while mountains have steep slopes and peaks.
