A hill is a peak of land above sea level, like a mountain, but lower and not as steep. These geological formations can be formed by erosion or deposition of sediment. These areas can be grassy, or covered in trees, or devoid of vegetation as in a desert. Hills often fill the transition between flatter plains and rougher mountain areas. Note that there may well be some dispute between geographers and inhabitants as to whether a given terrain feature is a hill or a mountain.
Sometimes hills make good tactical positions as they can give defenders higher ground while forcing enemies to fight uphill. Because of this, many armies may construct fortresses on top of hills. This occupation may be contested by the native creatures of the hills however, such as hill giants or the burrow-dwelling halflings.
Agriculture in hilly regions faces a number of challenges, mostly to do with drainage, soil erosion and the difficulty of ploughing on a slope, but these have been overcome in a variety of ways and some crops actually seem to do better on a hillside than on flat land (grapes being a good example).
