They can also form barrier islands, like Padre Island in Texas. Rivers bring sand to the shore, which forms our beaches. These are constructive forces. Q: What type of forces are involved when deposited rock forms deltas or barrier islands? Choices: - gravity forces - accumulation forces - matter forces - constructive forces A:
constructive forces
