The sedimentary rock in question is sandstone.
Sandstone is a clastic sedimentary rock made up mostly of weathering sand size debris that accumulates where the waters are slower.
Sandstone is formed by all of the processes named above.
-weathering of the rocks
-erosion caused by water and wind
-transportation by water bodies
-deposition by the water masses where they are slower
-lithification under the pressure
-compactation while mixing with multiple other sediments.
