Explanation: Conglomerate is a rock consisting of grave or pebbles embedded in a matrix. Conglomerates typically contain finer grained sediment, e.g., either sand, silt, clay or combination of them. It takes a strong water current to transport and produce a rounded shape on particles in conglomerate.
Answer: The glacial-interglacial cycle is triggered by changes in Earth's orbit around the Sun, and, as a result, there is approximately 100,000 years between interglacials (or glacials).
