pearls are formed in clams and oysters with a foreign object such as a grain of sand in there shell put layers f calcite and calcium around the object. the sand on beaches and underwater is tiny bits of quartz and grinded coral even though coral isn't a rock but a living creature.

Why do clastic sedimentary rocks generally form underwater?
Clastic sedimentary rocks are generally formed underwater because water provides the necessary medium for the transportation and deposition of sediments. The energy from moving water helps carry and deposit the particles that eventually cement together to form clastic sedimentary rocks. Additionally, underwater environments offer a more stable setting for sediment accumulation compared to terrestrial environments.
Where are most sedimentary rocks found on continents formed?
Most sedimentary rocks on continents are formed in areas with large bodies of water, such as along coastlines, in river valleys, or in shallow marine environments. These environments provide ideal conditions for the accumulation and deposition of sediments which eventually compact and cement into sedimentary rocks over time.
What rocks are formed from broken rocks?
Rocks formed from broken rocks are known as sedimentary rocks. These rocks are formed from the accumulation and lithification of sediments, which can include fragments of other rocks, minerals, and organic material. Common examples of sedimentary rocks formed from broken rocks include sandstone, conglomerate, and shale.
What are rocks in the sea called?
Rocks in the sea are typically referred to as sea rocks or underwater rocks. They can also be called submerged rocks or marine rocks.
What sedimentary rocks are formed from the remains of plants and animals?
Sedimentary rocks formed from the remains of plants and animals are called organic sedimentary rocks. Examples include coal, formed from the remains of plants, and limestone, formed from the shells of marine organisms.
Most fossils are found in what A in rock layers which formed underwater b in rocks which were formed from cooling lava from volcanoes c in sand on seashores d in the waters of seas and lakes?
A. in rock layers which formed underwater
How do layers in sedimentry rocks form?
The land where the rock was formed was underwater when the rock was formed. Over the years layers of Sediment sank to the bottom. Pressure formed the sediments into rock.

What kind of rocks are in underwater caves Metamorphic Igneous or Sedimentary?
Not sure quite what you are asking about, but anyway it is more accurate to ask what kinds of rock hold the caves, not what rocks are in the caves. Most caves are in limestone, a sedimentary rock, irrespective of water-level. There are a few caves in igneous rock: lava-tubes in basalt-flows, but on land, not underwater. There are also a good many caves in marble, the metamorphic but still-soluble form of limestone; and again the water-level is secondary to the cave itself. A few caves exist in rock-salt, an evaporite.
Are metamorphic rocks naturally formed?
Metamorphic rocks are naturally formed. they are formed from natural changes that happen to other rocks.
How is sedimenary rocks formed?
Sedimentary rocks are formed from the earths surface when sediments hardens into rocks :]
What rocks are formed from broken rocks?
Rocks formed from broken rocks are known as sedimentary rocks. These rocks are formed from the accumulation and lithification of sediments, which can include fragments of other rocks, minerals, and organic material. Common examples of sedimentary rocks formed from broken rocks include sandstone, conglomerate, and shale.
What is formed first rocks or minerals?
Minerals are formed first then rocks
What are rocks called when they are formed by sand rocks and shells?
Rocks formed from sand, rocks, and shells are known as sedimentary rocks. Sandstones, mudstones, and limestone are common examples of sedimentary rocks that can be formed from these materials.
What rocks are igneous sedimentary and metamorphic?
Igneous rocks are those formed by the solidification of magma. Sedimentary rocks are formed by the lithification of the sediments which accumulate from the erosion of preexisting rocks of all types. They also included rocks form from animal and plant remains. Metamorphic rocks are formed when sedimentary or igneous rocks are heated and or squashed.
