A) True
B) False

Answer 1

A river is formed as it incises into the surrounding rocks and sediments, abandoning the floodplain and leaving a record of its historical size and location.

Step-by-step explanation:

True. A river is formed as it incises into the surrounding rocks and sediments, abandoning the floodplain and leaving a record of its historical size and location. As the river flows, it erodes the rocks and sediments, carrying fragments downstream and depositing them elsewhere. This process not only shapes the river's channel but also creates a record of the river's past.
