How does a river delta form? Select the words that complete the explanation.

• A river carries a large load of gravel. As the river approaches the ocean, its speed decreases, and it deposits the material to form a delta.

• A river carries a large load of pebbles. As the river approaches the ocean, its speed increases, and it erodes the material to form a delta.

• A river carries a large load of sediment. As the river approaches the ocean, its speed decreases, and it deposits the material to form a delta.

• A river carries a large load of sediment. As the river approaches the ocean, its speed increases, and it weathers the material to form a delta.
