metamorphic rocks
No, compressed layers of sedimentary rocks are not known as intrusions. Intrusions are igneous rock formations that form when magma is forced into existing rock formations and solidifies underground. Sedimentary rocks are formed through the accumulation and compression of sediments.
The different layers of a volcano are made from the lava and ash produced by the volcano. Some volcanoes have different thicknesses of layers or only one type of layer depending on the kind of eruption and how much ash it produces.
Sedimentary rocks like sandstone, shale, and limestone are formed when layers of sediments are compacted and cemented together over time. This process is known as lithification.
If the layer is of dead plants, it is a compressed layer known as a coal seam.

A rock composed of compressed layers (sometimes resembling a cake) are known as sedimentary.

To create a sedimentary rock, layers of sediment such as sand, mud, or minerals must be deposited and compressed over time. This process, known as lithification, involves the compaction and cementation of the sediment layers to form a solid rock.
The building up of layers of sediment is known as sedimentation. This process occurs when particles of rocks, minerals, and organic matter settle and accumulate on the Earth's surface over time, forming layers of sediment. Over millions of years, these layers can become compressed and cemented together to form sedimentary rocks.

Dust-sized particles of hardened lava are known as volcanic ash. They are created during volcanic eruptions when molten lava is explosively ejected into the air, cools rapidly, and shatters into tiny fragments before falling to the ground. Volcanic ash can travel long distances and have significant impacts on human health, agriculture, and the environment.
Sedimentary rocks made from fragments of rocks, minerals, and shells are known as clastic sedimentary rocks. Examples include sandstone, shale, and conglomerate. These rocks form when pre-existing rocks are weathered, eroded, transported, and deposited in layers.
They are called exons.
The earth materials existing above bedrock are typically categorized into layers known as soil horizons. These layers include topsoil, which is rich in organic matter and nutrients and supports plant growth; subsoil, which contains minerals leached from above layers; and regolith, which is a mixture of rock fragments and minerals. The composition and thickness of these layers can vary depending on factors like climate, vegetation, and geology.
