Question

River system in a open or close system

Answer 1

A river system can be considered an open system because it interacts with its surroundings and exchanges matter and energy with its environment. The river receives inputs such as water, sediment, nutrients, and organic material from its watershed, and exports these elements downstream. Additionally, rivers can exchange heat with the surrounding air and water bodies, and can be affected by human activities and natural events outside of the immediate watershed. This makes river systems dynamic and interconnected with other ecosystems and processes.
