Sedimentary rock forms from the layering of eroded rock. Over time, sediments, which consist of fragments of other rocks, minerals, and organic materials, accumulate and are compacted and cemented together. This process typically occurs in bodies of water, such as rivers, lakes, or oceans, where the layers build up over time. Examples of sedimentary rocks include sandstone, limestone, and shale.

What type of rock forms from layering of eroded rock?
Sedimentary rock forms from the layering of eroded rock material, which accumulates and undergoes compaction and cementation over time. Examples of sedimentary rocks include sandstone, shale, and limestone.
What feature of sedimentary rock is common to nearly every type of sedimentary rock?
The feature common to nearly every type of sedimentary rock is layering, known as stratification, which is formed by the accumulation and compaction of sediments over time. This layering provides information about the environment in which the rock was formed.
What pre-existing rock does siltstone form from?
Siltstone can be formed from the eroded and transported particles of any rock type.
What type of rock can become sedimentary?
Any type of rock, igneous, metamorphic or sedimentary, can become eroded and re-deposited and cemented together to become a new sedimentary rock.
Type of sedimentary rock made from compacted mud?
Mudstone is a type of sedimentary rock that forms from the compaction and cementation of mud or clay particles. It has a fine-grained texture and is typically composed of silt and clay-sized particles. Mudstone is commonly found in marine environments and is a relatively soft and easily eroded rock.
What type of rock forms from layers of sediment?
Sedimentary rock.
What rock type forms from molten rock?
Igneous Rock comes from molten rock.
When magma is forced up in to layers of rocks and hardens layers?
When magma is forced up into layers of rock and hardens between them, it forms a type of igneous rock called a sill. Sills are parallel to the layering of the preexisting rock and are typically thin, horizontal intrusions. Over time, sills can be exposed at the surface through erosion and weathering processes.
What type of rock forms when molten rock cools and soldifies?
Igneous rock
What type of rock forms in layers?
That would be sedimentary rock, and (honorable mention) occasionally metamorphic rock.
What type of rock forms most often near an active volcano?
The most common type of rock that forms near an active volcano is igneous rock. This type of rock forms from the cooling and solidification of magma or lava. Examples include basalt, andesite, and rhyolite.
What type of event has to occur to create an angular unconformity?
An angular unconformity forms when older tilted or folded rock layers are eroded, creating a flat surface. New horizontal layers are then deposited on top of this surface, resulting in an angular discordance between the older and newer rock layers.
