A divide
land
It's call divide or watershed.
A ridge of land separating river systems is called a water shed. Normally the land is very high up and mountainous.

the main river and all of its tributaries are called a river system. The land drained by the river system is called a drainage basin. Drainage basins are separated by the high land in between, known as a divide or watershed.
Dry land doesn't float on top of water like peas in a soup. It's anchored. The rock that is high enough is dry land, the rock that isn't is ocean floor. Ocean basins are just the same as river beds or lake basins, just bigger.
River basins play a crucial role in water availability by acting as natural catchment areas that collect precipitation and runoff, directing it into rivers and lakes. The size, topography, and land use within a basin influence how much water is stored and how quickly it flows. Additionally, river basins can affect the distribution of water resources, impacting agricultural practices, drinking water supplies, and ecosystem health. Effective management of these basins is essential for maintaining sustainable water availability for various uses.
A river basin drains all the land around a major river. Basins can be divided into watersheds, or areas of land around a smaller river, stream or lake. Large river basins, such as the Neuse and Cape Fear, are made up of many smaller watersheds. The landscape is made up of many interconnected watersheds.
Plateaus and basins are both landforms, but they have different characteristics. Plateaus are elevated flatlands with steep sides, while basins are low-lying areas surrounded by higher land. Plateaus are typically formed by geological forces such as uplift and erosion, while basins are often created by tectonic activity or erosion.
A river basin is an area of land drained by a river and its tributaries. It includes all the land where water flows towards the main river. River basins are important for managing water resources and ecosystems as they help regulate water flow and support diverse plant and animal life.
Oceans themselves are not drainage basins; rather, they are large bodies of saltwater that receive water from various drainage basins. A drainage basin, or watershed, is an area of land where all precipitation collects and drains into a common outlet, such as a river, lake, or ocean. In this context, rivers and streams within drainage basins ultimately carry water to oceans, making the oceans the final destination for the water collected in these basins.
