Answer:
The Mississippi River formed Louisiana's coastline by eroding land which creates the coastline. The Mississippi river benefits Louisiana by being a river to trade in, a way of getting water, and being a tourist attraction that Louisiana profits from. Coastlines are formed by waves clashing with materials on a land. Over time, the clashes of land erode (take apart) the land, which forms a coastline. Without the Mississippi river, Louisiana would not have a tourist attraction in the form of a coastline and river, water would not be easily available to Louisiana, and Louisiana wouldn't see as much trade.
Explanation:
All land (in this case, coastlines) is shaped by waves. When the waves go at the land, the land loses itself in little tiny pieces overtime, which helps to shape land as we know it. Rivers are known to have lots of seafood and/or are of importance as rivers have water, which is required for human life, so the river is important to Louisiana.
