how do rivers become larger as they travel across land? groundwater rises, adding water to rivers. tributaries combine, adding water to rivers. ice sheets melt slowly, adding water to rivers. rainfall in an area increases, adding water to rivers.
Answer
Answer:
B. Tributaries combine, adding water to rivers.
Brief Explanations:
As rivers flow, tributaries (smaller streams and rivers) join them, increasing their volume and making them larger. Ground - water rise, ice - sheet melting, and increased rainfall can contribute water but tributary combination is the main way rivers grow in size as they travel across land.
