What ate the four types of general landforms how do geographers define them and what are the characteristics of each one?

Mountains, hills, plateaus, and plains are the four major types of landforms. Minor landforms include buttes, canyons, valleys, and basins. Most geologists classify a mountain as a landform that rises at least 1,000 feet (300 meters) or more above its surrounding area. A hill is a landform that is higher than the surrounding land and has a visible summit; they're like mountains, only shorter. A plateau is a flat, elevated landform that rises sharply above the surrounding area on at least one side. A plain is a broad area of relatively flat land.
