Which process involves the transportation of material by dissolving it in water?

The process that involves the transportation of material by dissolving it in water is known as solution. In the context of rivers and water flow, solution refers to the process where soluble minerals and nutrients are carried along with the water itself after they have dissolved. This is crucial for the transportation of various substances, such as salts and minerals, which can be easily integrated into the aquatic environment.

Unlike other processes, such as traction, suspension, and saltation, solution does not involve the physical movement of particles along the riverbed or through water as separate entities. Rather, it represents a chemical process where the materials become part of the water, allowing for the effective distribution of essential nutrients and minerals throughout the aquatic ecosystem. This process is vital for maintaining the health of the river and the organisms that inhabit it, highlighting the significance of solution in river systems.
