1) Mountains: These are elevated landforms of the earth's surface, rising thousands of feet above their surrounding. Mountains often form part of a mountain range, a linear sequence of peaks and ridges connected by valleys.
2) Plateaus: These are large, flat-topped elevation landforms that are higher than the surrounding terrain, but with limited ruggedness. Plateaus are often found at high elevations and can be the result of tectonic uplift, erosion, or deposition.
3) Plains: These are area of low elevation with relatively flat topography. Plains can be formed through various geological processes, including erosion, deposition, or tectonic activity.
