How are talus slopes built?

Question

Quizplus · Accepted Answer

Talus slopes are typically built by the accumulation of rockfall debris that has fallen from the slopes above. As rocks weather and erode, they break apart and fall down the slope. Over time, the accumulation of fallen rocks can form a steep and unstable talus slope. Glacial transport and debris flows are also involved in the formation of some talus slopes, but rockfalls are the primary mechanism in most cases. Intense low temperature chemical weathering does not build talus slopes.
