Which of the following illustrates the formation of a delta?
A sediment is deposited where a river flows into an ocean or lake.
B sediment is deposited where an ocean flows into a river.
C sediment is deposited where a stream leaves a mountain range.
D sediment is deposited where a lake enters an ocean.
The answer is A! Deltas are found at the end of rivers, where they meet a larger body of water. Take the Nile River Delta for example. The Nile River flows north into the Mediterranean Sea. Where the river and the sea meet, there is a delta.
