You are a geologist trying to determine if the slope on which your client’s house sits is stable. you determine that the angle of repose of the hillside is 35 degrees. which of the following situations would be considered stable?
a. the slope is composed of saturated sand.
b. the slope is composed of dry sand.
c. the slope is composed of damp sand.
d. the slope is composed of dry gravel.

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.  

Your answer is d. silli hope this ! : ) i left an explanation down below if you need it: a sill forms when hot magma squeezes between layers of rock to form a hardened sheet of rock. a sill is basically a tabular sheet intrusion between old layers of sedimentary rock, volcanic beds, or in the direction of foliation inherent in metamorphic rock. the word sill means a concordant intrusive sheet.

Don't depend on this but logically i think c
