Sedimentary rock, possibly conglomerate.

A sandbar is typically formed by deposition, as sediment is carried by water and deposited in shallow areas. However, erosion can also play a role in the formation of sandbars, as strong currents or waves can erode existing landforms and contribute to creating sandbars.
Baymouth bars form across bays at the entrance, where sediment is deposited by longshore drift to create a barrier that separates the bay from the open ocean. This feature results in shallow water inside the bay and can impact navigation and water circulation within the bay.
Waves break along the shoreline when they encounter shallow water, causing the bottom of the wave to slow down while the top continues moving forward, leading to the wave crest toppling over and breaking.
Barrier islands are formed through a combination of sea level rise, sediment accumulation, and wave action. Waves and currents transport sediments, which then accumulate along the shallow offshore areas, gradually building up the barrier islands. Over time, as sea levels rise, these sediment deposits are shaped into long, narrow barriers parallel to the mainland coast.
Conglomerate rock is most likely formed from pebble-sized sediment deposited in shallow water at an ocean shoreline. The pebbles are typically rounded due to erosion in water, and they can become cemented together to form the conglomerate rock.

In a sediment collecting basin, clay is typically deposited closest to the shore. This is because clay particles are very fine and can remain suspended in water for longer periods, allowing them to settle out in calmer, shallow areas near the shore. Sandstone and siltstone, which are composed of larger particles, tend to be deposited further offshore where water energy is higher and sediment transport is more vigorous.

Contenental Shelf.
Contenental Shelf.
The shallow extension of the continent that extends beyond the shoreline is called a continental shelf. It is the submerged part of a continent that extends from the shoreline to a drop-off point called the shelf break.
Sandbars occur when sediment is deposited by water, usually in shallow areas such as rivers or coastlines. They can form due to changes in water flow, wave action, or changes in sediment supply. Sandbars are dynamic features that can change over time due to natural processes.
The term for the part of a continent that extends beyond the shoreline beneath relatively shallow seawater is the continental shelf. It is an underwater extension of the continent that slopes gently from the shore to the ocean depths.
A sandbar is typically formed by deposition, as sediment is carried by water and deposited in shallow areas. However, erosion can also play a role in the formation of sandbars, as strong currents or waves can erode existing landforms and contribute to creating sandbars.
Smal ones..
A continental rise forms where the continental slope levels off, and sediment accumulates due to gravity transporting sediments downslope from the slope above. This is a gentle accumulation of sediments deposited by turbidity currents, rivers, and other geological processes at the base of the slope.
