Where do sedimentary rocks come from above ground or underground?
Sedimentary rocks are typically formed above ground through the accumulation and compaction of sediment particles such as sand, clay, and organic material. These sediments may originate from weathering and erosion of existing rocks. Once deposited, pressure and cementation over time solidify the sediments into sedimentary rocks.
Which of the following conditions are necessary to cause loose sediment to become sedimentary rock?
The necessary conditions for loose sediment to become sedimentary rock are compaction, which involves the squeezing together of sediment grains, and cementation, which involves the binding of grains together by minerals like calcite or quartz. Over time, these processes form solid rock.
What are two reasons the particles in a sedimentary rock stick together?
Particles in sedimentary rocks stick together because of compacting pressure from layers of sediment above them, and because of natural cements like calcite or silica that fill the spaces between particles and bind them together.
How is weathering related to the formation of sedimentary rocks?
Weathering is the breaking down of existing rock into smaller pieces that are transported by erosion to a place of deposition, which can lead to compaction and cementation--two processes necessary in the formation of sedimentary rock.
The process in which the weight of sediment above squashes together the sediments below?
The process you are referring to is called compaction. This occurs as the weight of overlying sediment compresses and squeezes the sediments below, reducing pore space and increasing the density of the sediment layers. Compaction is an important step in the formation of sedimentary rocks.

Are sand pebbles water and plaster mixed together an igneous metamorphic or sedimentary rock?
At this point they are none of the above. They are sediment. If lithified they will form sedimentary rock.
An igneous rock becomes a sedimentary rock when what occurs?
When an Igneous rock is broken down by physical processes it can become sediment, carried along rivers and waterways to reach the sea and the oceans. When upon the seabed, it is slowly covered by other sediment, and the combined force of the water above and sediment above working with sea mud and other sea deposits forms sedimentary rock.

How does sediment rocks form?
Sedimentary Rocks are formed when when sediment peices from other rocks are put under pressure from Above and presses them into minerals Sources: Common Knowledge/Science class :bradleyss
Which action will change a sedimentary rock into a metamorphic rock?
Heat from magma and pressure from above ground.
How do layers change into rocks?
Sediment layers are squeezed from above by the weight of overlying sediment, causing compaction. Compaction squeezes out air and water between the sediment particles. Minerals form as the air and water is squeezed out, cementing the particles together, and forming sedimentary rock.
What process can lead down to a metamorphic rock becoming a sedimentary?
Erosion. If a metamorphic rock is exposed above sea level it will erode or weather, the products from this erosion or weathering will be moved by gravity, wind or water to a sea or basin where the products will settle as a sediment. If the conditions are right the sediment will eventually become a sedimentary rock.
Are sedimentary rocks made on the Earth's surface?
Sedimentary rocks form at the bottom of bodies of water, as more and more layers of sediment build up above them. Compared to the depths at which metamorphic rocks form, and some of the places igneous rocks form, these are indeed close to the Earth's surface.
