- Mountainous regions: The steep slopes of mountains create a strong gravitational pull, causing water to flow rapidly. Examples include the Himalayas, the Andes, and the Rocky Mountains.
- Highland areas: Similar to mountainous regions, highland areas with significant elevation differences can generate fast-moving rivers and streams. Examples include the Scottish Highlands, the Ethiopian Highlands, and the Tibetan Plateau.
- Glacial regions: Melting glaciers release large volumes of water, which can form fast-moving rivers and streams. Examples include regions near the Greenland ice sheet, the Antarctic ice sheet, and glaciers in Alaska and the Canadian Rockies.
- Coastal areas with steep terrain: In some coastal areas, the land near the shoreline may have steep slopes, resulting in fast-flowing rivers and streams that empty into the ocean. Examples include the Pacific Northwest coast of North America, the fjords of Norway, and the Milford Sound region in New Zealand.
