Waves hiting at an angle and then bending around features of the coast is known as___________ b. Landforms associated with longshore drift form where the________ is pierthd enough to create them. c. When there is longshore dift, the overall drection of sand transport is________ to the coast. d. In order to produce longshore drift, the direction of waves must not be_________ to the coast. e. A_________ forms when longshore drit creates a ridge of sand separating a waterway from the ocean. f. The direction that sediment is traveling along a coast is called the__________ direction.

Answer 1

1. Waves hitting at an angle and then bending around features of the coast is known as wave refraction.

2. Landforms associated with longshore drift form where the sediment is plentiful enough to create them.

3. When there is longshore drift, the overall direction of sand transport is parallel to the coast..

4. In order to produce longshore drift, the direction of waves must not be perpendicular to the coast.

5. A baymouth bar forms when longshore drift creates a ridge of sand separating a waterway from the ocean.

6. The direction that sediment is traveling along a coast is called the downstream direction.

Explanation:

Waves forms different kinds of land form in the coastal areas. Waves hit coast in a particular angle It is known as wave refraction. When sediments get deposited in the coastal areas and forms a bar which get detached from the shore is called long shore bar.

To create long shore drift the direction of wind should not be perpendiular to the coast. Direction will be parallel. A baymouth bar is formed when a ridge of sand is created and separates the waterway from ocean. Sediments travel along the coast in downstream direction.
