chemical weathering
The natural shifting of a river's course has caused the river to separate into two branches. One branch continues in the river's previous course. The other branch takes a new route across the land. Eventually, it empties into the ocean. Which landform will most likely form where the new branch empties into the ocean? (1 point)
canyon
hill
mountain
delta
