Areas between hills, also known as valleys or dales, are geographical features that are formed when two hills or mountains are close together and the land in between them is lower than the surrounding land. Valleys and dales are often characterized by their U-shaped cross-section and can be found in many different types of terrain. Valleys and dales are often used for agricultural purposes, as they provide a sheltered environment for crops to grow. Valleys and dales are also popular tourist destinations, as they offer stunning views and unique landscapes.
