Which of the following sedimentary rocks would you expect to have originally been deposited by fast-moving streams? A. MudsoneB. Oolitic limesoneC. GreywackeD. Conglomerate

The rock that has a high fast moving streams is Conglomerate. So the correct answer is D. Conglomerate.

Conglomerates are special sedimentary rocks that develop in a mixture of finer sand or silt when rocks and pebbles are cemented together.

High-energy streams can carry and deposit larger clasts of gravel or pebble size. Conglomerates also indicate that in the middle course of the stream the deposition of the rocks occurred when the energy is relatively high.

Explanation:

The formation of conglomerates requires homogenization with larger rocks and pebbles of sand, mud, clay or silt. In fast-moving streams, ocean waves, landslides, or glaciers, this most commonly happens.

This mixture is compressed into solid rock over millions of years. Conglomerates can contain virtually any rock or mineral size or type mixed in almost any base of clay, mud, sand or silt.
