How was the Mississippi formed?

The Mississippi delta was formed over 7,000 years in a process called the delta cycle. When sediment starts to deposit underwater plants start to grow and a delta starts to form. A series of deltaic lobes formed over 7,000-8,000 years. Over the centuries the delta formation slowed down.

How it is today.

Rivers get bigger after a while and when the do they flood their surroundings. Rivers erode rocks in their path leaving a rocky bottom. Small streams join with bigger rivers. Then rivers start getting even bigger. River start to curve or start changing course. Then after a while a delta starts forming.
