- Contains areas of standing water and peat bogs, due to the combination of high rainfall and impermeable rock.
- V-shaped river valleys formed by the numerous surface streams. Valley sides are steep due to the resistant nature of the granite.
- Contour lines are found close together on a map.
- The land is at a higher altitude than the surrounding area due to the resistant nature of the granite.

- Extraction of china clay. Kaolin, also known as china clay, is a product of hydrolysis and is used in ceramics and paper-making. The industry is very important for the local economy and employment.
- Quarrying. Granite blocks were used for dry-stone walling, buildings and road stone. Many quarries are now abandoned.
- Tourism. Dartmoor is a National Park, popular for walking, camping and pony trekking. Over 10 million people visit the area each year.
- Farming. The soils are poor and acidic, and frequently used for sheep farming rather than growing crops.
- Mining. Copper and tin mining used to be common in the area. The metals were found in thin veins within the granite.

- Quarrying, mining and china clay extraction can leave scars on the landscape, making it less attractive for both tourists and local people.
- Tourism causes pollution and congestion on the roads. Tourist activities can sometimes lead to conflict with local people.
- Tourists buy second homes, pushing up property prices so that locals cannot afford to buy. Rural poverty is becoming a problem in areas such as Dartmoor.
