1. What is the boundary definition?Delineated by a drainage divide, typically elevated landforms that separate adjacent basins
2. What is the structural organization?Often exhibit a hierarchical pattern, with smaller sub-basins feeding into larger ones
3. How does a drainage basin shape the land?As water moves through the basin, it erodes soil and rock, carrying sediment and nutrients downstream. This erosion and deposition change the shape of the land over time.
4. Why are drainage basins important for people and animals?They give us fresh water for drinking, farming, and factories. Healthy basins also keep rivers, lakes, and forests full of life.

Drainage divide: The elevated topographical boundary separating adjacent drainage basins, dictating water flow direction.
Confluence: The point where two or more streams or rivers merge, forming a larger watercourse.
Endorheic basin: A closed drainage basin where water collects internally, often in lakes or sinks, without reaching the sea.
