The four main types of landforms are mountains, hills, plateaus, and plains. Other minor landforms are canyons, valleys, and basins. These are natural features that make up a terrain.
Mountains are steep landforms that are 1,000 feet or more above nearby land. Mountains are further classified into volcanic, dome, and fault-block mountains. Hills are similar to mountains in height, but not as steep. Different types of hills are drumlin, butte, tor, puy, and pingo. Plateaus are also raised surfaces but with relatively flat tops. Some examples are the Tibetan Plateau and the Colorado Plateau. Plains are flat landforms without elevation. Kinds of plains are flood, alluvial, river, and coastal plains.
