What is the more appropriate term for river branches in a delta?

Correct answer: Distributaries

Direct answer: Option B, distributaries. A distributary is a smaller channel that branches away from the main river, especially near its mouth in a delta. Step by step: a river carries sediment toward the sea; deposition raises and divides the channel; the river splits into several smaller outward-flowing channels; these are distributaries. Option B is correct. Option A, volcanic vents, are openings through which volcanic material may emerge and are unrelated to delta channels. Option C, ice cracks, occur in frozen surfaces and have no connection with ordinary delta branching. Option D, desert channels, are channels in dry regions and do not name the branches of a delta river. A tributary joins a main river, while a distributary leaves it. Memory cue: tributary comes to the river; distributary departs from it.
