2. A delta is a landform that can be found at the mouth of a river. How is a delta formed?

• Ocean waves deposited sand and sediment as they crashed on the shore.
• As the river reached the ocean, the flow slowed down. This caused sediments to be deposited in a triangular formation.
• A river's flow sped up as it reached the ocean. This caused sediment to spread outward when it reached the coast.
• Waves from tropical storms caused coastal erosion, and the remaining coastline was shaped to create the landform.
