Sponges are bottom-dwelling creatures that attach themselves to something solid, such as a rock. They rely on the system of the water canal to deliver food and oxygen to them. Sponges consume plankton.
Not necessarily. While nearly all fossils, including seashells, are found in sedimentary rock, most sedimentary rock does not contain fossils. Even then, those fossils will not necessarily be seashells. If you do find a rock with seashells, though, you can be pretty much guaranteed that it is sedimentary.
Yes, seashells can be considered a sediment. When seashells accumulate and compress over time, they can become cemented into sedimentary rock formations such as limestone. This process is part of the sedimentary rock cycle.
Magical Seashells.

A rock that contains fossil seashells was most likely formed as a result of sedimentation.
The rock was most likely formed through the process of sedimentation, where layers of sediment accumulated over time and eventually turned into rock through compaction and cementation. The fossil seashells in the rock suggest that the area was once covered by a sea or ocean where these organisms lived and were preserved in the sediment as it solidified into rock.
You are likely to find embedded seashells in limestone, which is a type of sedimentary rock formed from the accumulation of coral, shells, and other organic material.
A rock that contains fossil seashells was formed through a process called sedimentary rock formation. Over time, seashells and other organic materials accumulated on the ocean floor, where they were buried by layers of sediment. As pressure increased and minerals precipitated from water, these sediments cemented together, preserving the fossilized remains of the seashells. This process can take thousands to millions of years, resulting in rocks such as limestone or shale that contain these fossils.
Seashells are not classified as rocks. They are composed of calcium carbonate and formed by marine animals as protective outer coverings. While they may be found in rocky areas, seashells are biogenic, meaning they are produced by living organisms, whereas rocks are inorganic solid materials.
A rock made entirely of seashell fragments is known as a coquina. Coquina rocks are formed from the accumulation and compression of broken seashells, creating a unique and porous sedimentary rock that is often found along coastal regions.
Not 'mud', it is the remains of shells and skeletons of dead sea creatures, as well as precipitated calcite that eventually lithify to form limestone.
