Answer 1

Answer:

1. A sand dune is a mount, hill or ridge of sand that lies behind the part of the beach affected by

tides.

2. A beach forms when waves deposit sand and gravel along the shoreline.Beaches are made up from eroded material that has been transported from elsewhere and then deposited by the sea. For this to occur, waves must have limited energy, so beaches often form in sheltered areas like bays. Constructive waves build up beaches as they have a strong swash and a weak backwash.

ITS A BRIEF EXPLANATION OF Q.NO.1

ANSWER OF Q NO. 2

Beaches are wave-deposited accumulations of sediment located at the shoreline. They require a base to reside on, usually the bedrock geology, waves to shape them, sediment to form them, and most are also affected by tides.
