Valley
In country that has hills, but is not very steep, a river or stream runs more slowly. It makes a wider valley that often has some large bends as the river flows around the hills, always following the lowest way. Water running down from the hillsides often carries soil that spreads out across the valley, making flat land that is good for growing food crops and raising cattle and other animals. Many farms are in valleys that are in hilly land. Many towns are built on the sloping sides of valleys. Famous valleys of this type are the Loire Valley and the Lower Rhine Valley in Europe and the Thames Valley in England.
