Sedimentary Rock
because magma are molten materials which exist below the solid rock of the earth's crust .we sedimentary rocks are formed by the result of deposition or accumulation and lithification of sediments of some weathered particles and other different materials therefore magma not often made because they don't contain fossils
Sedimentary rocks are made from particles called sediment. They are made from layers of sediment (small particles) on the bottom of rivers or seas. The sediments are compressed as more layers build on top of them. The particles then become cemented together to form solid rocks. The layers of rock are called strata. Sedimentary rocks have a grainy structure and they easily crumble.
Sedimentary rocks are formed from buildup of sediment, or particles of dirt and organic debris and things like that. Think of sedimentary rocks like the bottom of a river bed- stuff builds up on top until it becomes hard and solid- a rock, so pressure is a factor, but not necessarily heat. It is usually metamorphic rocks that involve both heat and pressure.
Cementation is the process of deposition of dissolved mineral components in the interstices of sediments. It is the sticking together of sediment to form a new rock and is an important factor in the consolidation of coarse-grained clastic sedimentary rocks such as sandstones, conglomerates, or breccias during diagenesis or lithification. Cementing materials may include carbonates, quartz, iron oxides, or clay. (Source wikipedia)
Sedimentary Rock
The three processes that occur during the formation of sedimentary rocks are weathering, erosion, and deposition. Weathering breaks down rocks into smaller particles, erosion transports these particles to different locations, and deposition involves the settling and accumulation of these particles to form sedimentary layers. Over time, these layers are compressed and cemented to form solid sedimentary rocks.

The five major processes involved in the formation of sedimentary rocks are weathering, erosion, transportation, deposition, and lithification. Weathering breaks down rocks into smaller particles, erosion moves these particles, transportation carries them to new locations, deposition settles the particles in layers, and lithification compacts and cements the sediments into solid rock over time.
An example of deposition is when sediments settle and accumulate at the bottom of a river or ocean over time, forming layers of sedimentary rock. This process occurs as the energy of moving water decreases, allowing particles to be deposited and build up into solid rock formations.
In unified science, deposition refers to the process where particles or materials from a gaseous state directly transform into a solid state without passing through the liquid phase. This can occur through various mechanisms such as sublimation or chemical reactions. Deposition plays a role in phenomena like vapor deposition in materials science or the formation of frost in nature.
Examples of deposition include the formation of sedimentary rocks such as sandstone and shale, the accumulation of snow to form glaciers, and the settling of dust particles on surfaces. Deposition also occurs in chemical processes when gases transition directly to solid form, such as frost forming on a cold surface.
Some sedimentary rocks form as a direct result of the accumulation and cementation of sediment particles, such as sand, mud, or gravel. Over time, these sediment particles are compacted and cemented together to form solid rock layers.
Sedimentary rock is formed when rock fragments, mineral grains, or organic particles are compacted and cemented together over time. This process occurs through the deposition and lithification of sediment in layers. Examples of sedimentary rocks include sandstone, limestone, and shale.
Lithification is the process by which loose sediment compacts and cements together to form solid rock. This often involves the combination of pressure, temperature, and the deposition of minerals that bind the sediment particles together. The end result is the formation of sedimentary rocks, such as sandstone or shale.
Deposition mainly occurs when the energy of a system decreases to the point where particles lose motion and come together to form a solid. This process is most commonly observed when a gas transitions directly into a solid without passing through the liquid phase, such as snowflakes forming from water vapor in the atmosphere.
There are three main steps to create a clastic sedimentary rock: weathering and erosion of existing rocks, transportation and deposition of the sediment, and compaction and cementation of the sediment to form a solid rock.
