The process that presses sediments together is compaction. Thick layers of sediment build up gradually over millions of years. These heavy layers press down on the layers beneath them. The weight of new layers further compacts the sediments, squeezing them tightly together. The layers often remain invisible in sedimentary rock.
it gets weathered into sediment, then it gets washed into the ocean, sediment layers up over millions of years, and it gets squashed into sedimentery rock, then metamorphic and so on.
A geologic record means something which is present in the Earth's surface between various layers of sediment. By determining which layer they are present in, geologists are able to understand the time period something was originally placed there.
Main locations of sedimentary rock is at the bottom of a water source such as an ocean.As rivers flow to the sea, they may carry mud, sand, pebbles, and boulders along the way. The river drops this material, called sediment, into the sea. As layers of sediment build up over a period of many years, the great pressure of all these layers changes the sediment into sedimentary rock. Therefor you might be able to find sedimentary rock at the bottom of the ocean or a lake or river.

Weathering, erosion, and deposition.

Layers of sediment are pressed under the earth for thousands and millions of years, and solidify into rock.

Over millions of years, layers of sediment may build up and harden into sedimentary rock. Some of the many forms of sedimentary rock include sandstone, rock salt, and coal. Sandstone forms as sand hardens.
It is sand. Edit: Over many thousands of years - sediment gets compressed and compacted into layers. The layers form rocks such as slate and coal.
Weathering. Sediment is a type of rock composed of layers dating back to thousands of years.
something that dies then u have to have it buried in sediment rock and pressure no heat then millions of years
Sedimentary rocks
Simply because oil-bearing rock was formed millions of years ago, and is buried deep in the Earth's crust, due to being covered by successive layers of sediment.
FOSSILS are found in sedimentary rocks. sedimentary because the rocks have been under water for over millions years and build layers till it made a cliff. THIS IS ROCK CYCLE
