inal answer:
The typical composition of each clast size in sedimentary rocks varies depending on the type of rock. Clastic sedimentary rocks are classified based on their grain size, which includes the size and composition of the clasts.
Step-by-step explanation:
The typical composition of each clast size in sedimentary rocks can vary depending on the type of rock. Clastic sedimentary rocks are classified based on their grain size, which includes the size and composition of the clasts. The clasts can range from fine-grained (small particles) to coarse-grained (large particles). For example, sandstones are composed mainly of sand-sized particles, while conglomerates are made up of larger clasts such as gravel and pebbles.
It's important to note that the composition of each clast size can also provide information about the transport and depositional history of the sediment. Geologists may use grain size analysis to classify and describe the sediment, as well as to determine the environment in which the rock was originally formed.
Overall, the typical composition of each clast size can vary in different sedimentary rocks, but it plays a crucial role in understanding the characteristics and origins of these rocks.
