Verified
A very well sorted sandstone with large-scale cross-bedding indicates the sand was likely:
A) deposited by the wind in dunes
B) deposited by water in a braided river system
C) deposited by water in a meandering river system
D) deposited by a turbidity current offshore
Well Sorted
A condition of sedimentary particles that display a narrow range of sizes due to the action of transport and deposition processes.
Cross-bedding
A geological feature that forms as inclined layers of sediment are deposited across a horizontal surface, indicating ancient water or wind flows.
- Determine and detail the conditions under which different sedimentary rocks are formed.
