2. A beach is the land along the edge of a body of water and is usually made up of any number of materials sand, gravel, pebbles, cobbles, rock, or shells. Beach material accumulates on the beach during periods of accretion or moves away from the beach during periods of erosion. Never stationary for long, beaches are always moving. Beaches can be hundreds of kilometers long or very short. The coast is a more general term referring to the junction of land and water, but a beach is made of specific materials like sand, cobbles, or shells. San grains allow water to quickly flow through, so even though it’s near the ocean,, beaches tend to be water limited. In addition, a few organisms are able to survive in sandy habits due to the loose grains that are readily moved by waves. The longer the wind blows the bigger the waves; stronger winds mean higher waves; and the greater the fetch, the bigger the waves. Thus the biggest waves of all occur in the storms that last the longest with the most energetic winds with hundreds of miles between the storm at sea and the beach. Waves do not actually consist of water traveling from where the wind is blowing all the way to the beach. Instead of moving water, waves are moving energy that was transferred from the wind to the water. This energy propagates, or moves, through the ocean to the beach in the form of a wave. But the water itself is not moving forward as in a current. Instead, the energy rolls through the water in a circular motion called a wave orbital.
What is the most common type of organism found in the ocean? Blood worms, are one of the most abundant sandy beach animals. These blood worms may occur in tremendous numbers in the mid intertidal area of a sandy beach. They are called blood worms because of the red color of their bodies, their bodies stretch through the moist sand sometimes up to a foot long. They can be found up to about eight inches in
