Help? You are studying an outcrop where the lower layer is limestone and the layer directly on top of the limestone is sandstone
ELEN [110]

Answer:

Due to mixing of particles present in the upper layer of limestone with sandstone during deposition.

Explanation:

The parent layer was limestone layer which is older than sandstone layer. This sandstone layer spreads on the limestone layer because of wind. The wind moves these sandstone from other region and their deposition occurs on the limestone layer. During deposition of sandstone, some particles of limestone which are present at the surface mixes with the sandstone so that's why in sandstone layer, small and weathered pieces of limestone are present.
