Sedimentary rocks.
Rocks formed by layering.
Clastic sedimentary rocks are composed of particles of weathered and eroded or fragmented in situ rocks of varying mineralogy.
The layering that occurs in sedimentary rocks is called bedding or stratification. Bedding is formed by the deposition of sediments in discrete layers over time, while stratification refers to the overall layering pattern in a rock formation.
Water is not a form of pyroclastic material. Pyroclastic material refers to fragmented volcanic rocks, ash, and other debris expelled during volcanic eruptions.
Intrusive igneous rocks.
weathered remains of other rocks
a molten rock
"layering" As in "layered" igneous intrusion.
Sedimentary rocks are formed from pre-existing rocks or pieces of once-living organisms. They form from deposits that accumulate on the Earth's surface. Sedimentary rocks often have distinctive layering or bedding.
Sedimentary rocks are formed by the layering of materials, as new layers are added, they compress the lower layers which eventually physically adhere together.
Igneous rocks typically do not have distinct layers, as they form from the solidification of molten material (magma or lava) that cools and crystallizes. Unlike sedimentary rocks, which are formed from the accumulation of sediment in layers, igneous rocks are usually homogeneous and can be either intrusive (formed beneath the Earth's surface) or extrusive (formed at the surface). However, some igneous rocks may exhibit layering due to processes like differential cooling or the presence of varying mineral compositions, but this is not a defining characteristic.
Sedimentary rocks, such as sandstone or shale, erode to expose layering due to the distinct horizontal beds created during the deposition process. The layering, or bedding, in sedimentary rocks forms as sediments settle and accumulate over time, preserving a record of the Earth's past environments and processes.
