Changing Earth Surface Practice Test

A map of a mountain slope is shown at two times. At Time 1, a hiking trail crosses a steep slope. At Time 2, the map shows a fresh, bare patch on the slope and a pile of rock and soil at the bottom of the slope that was not there before. Multiple processes can contribute to surface change over time.

What change is shown in these maps?

Two maps show the same hillside with exposed rock at two times. At Time 1, the rock outcrop has sharp edges and fewer cracks. At Time 2, the same outcrop shows many more cracks and small rock fragments collected just downslope. Multiple processes may contribute to surface change over time.

Which explanation fits the observed change best?
