A river carries sediment downstream and eventually drops it at its mouth, forming a delta. Which BEST explains why this process shows both constructive and destructive forces?
A. The river wears away land upstream and deposits sediment downstream.
B. The river destroys mountains and creates earthquakes.
C. The river creates new volcanoes and washes away sand dunes.
D. The river builds beaches while also breaking rocks into minerals.
A. The river wears away land upstream (destructive) and deposits sediment downstream (constructive).

E. Sand dunes are the early stages of a mountain forming in a desert.
F. Sand dunes are made of sand from large areas of the surrounding desert.
D. Sand dunes dunes are formed when sand moved by wind and rain collects.
F. Sand dunes are made of sand from large areas of the surrounding desert.
Over thousands of years, a mountain slowly becomes smaller and a delta grows larger at the mouth of a nearby river. Which statement BEST explains this change?
A. The mountain is shrinking because deposition is breaking rocks apart.
B. The mountain is shrinking from weathering and erosion, while the delta is growing from deposition.
