Answer:
d. The slope is composed of dry gravel.
Explanation:
Angle of repose is the maximum steep or angle a heap of sediment will form without been unstable or slump. This simply means at the angle of repose the sediment is at the verge of sliding or slumping.
At angle lesser than repose, gravitational force which assist slumping cannot overcome frictional force which goes against slumping. Therefore the sediment possess the ability to become steeper, resist sliding and retain stability as more sediment accumulates.
The measured angle of repose of the hill is 35°. The angle of repose for dry gravel ranges from 30 ° to 45 ° . Therefore it has the ability to retain stability since it range of repose accommodate for more sediment until it meet the angle of repose.
