____ would indicate deposition occurred in a high-energy environment.

Question

Quizplus · Accepted Answer

Conglomerates are composed of large, rounded grains that were transported by high-energy forces such as fast-moving water or strong wind. This indicates deposition in a high-energy environment. The other options do not necessarily indicate a high-energy environment. Pelagic oozes are composed of fine-grained particles that settle slowly in deep ocean waters. Shales are composed of fine-grained particles that were deposited in calm, low-energy environments. Clay-rich rocks may indicate deposition in a variety of environments, including both high- and low-energy. Glacial till is composed of a mix of unsorted rocks and sediment deposited by melting glaciers, but it may not necessarily indicate a consistently high-energy environment.
