What kind of sedimentary rocks are formed when sediments are deposited in layers at the bottoms of lakes and oceans?

sedimentary rock formed by weathering and erosion


Can sedimentary rocks form under the ocean or on land only?

Sedimentary rocks formed under oceans, but the ocean may no longer be there. The Great Lakes region was once all under water and has much sedimentary rock.


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.


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 kind of sedimentary rocks are formed when sediments are deposited in layers at the bottoms of lakes or oceans?

The rock formed would usually be classified as clastic sedimentary rock, like shale.


Rocks formed from weathered debris from preexisisting rocks are called?

They are called clastic sedimentary 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.


How was asandstome formed?

Sandstone rocks are formed from sedimentary rocks. It is when sedimentary rocks are broke down into small pieces.


Can a moon rock become sedimentary rocks?

no because sedimentary rocks are made at the bottom of oceans


WHAT IS ANOTHER NAME FOR SEDIMENTARY ROCKS?

Another name for sedimentary rocks is "stratified rocks," due to their layered appearance formed by the accumulation and compaction of sediments. These rocks often contain fossils and are typically formed in environments like rivers, lakes, and oceans. They can also be referred to as "clastic rocks" when they are primarily composed of fragments from other rocks.


Is sedimentary rocks formed the same way normal rocks are?

No, because a sedimentary rock is formed from pieces of other rocks.


Rocks formed from sediments deposits?

Sedimentary rocks are formed from sediment deposits (gravel, sand, silt, clay) over long periods of time either on land or in water (lakes, oceans). As more and more sedimentary layers are deposited, the newer layers exert pressure on the older layers, which compacts the loose particles and cements them together - forming sedimentary rocks. Sedimentary rocks can also be formed through the precipitation of dissolved minerals to form limestone or dolomite.
