Answer: a. compaction Sedimentary rock
Which process squeezes layers of sediment together? Space Technology

Sedimentary structures include all kinds of features formed at the time of deposition. Sediments and sedimentary rocks are characterized by bedding which occurs when layers of sediment with different particle sizes are deposited on top of each other. These beds range from millimeters to centimeters thick and can even go to meters or multiple meters thick.

Ionium–thorium dating is a related process which exploits the insolubility of thorium (both 232 Th and 230 Th) and thus its presence in ocean sediments to date these sediments by measuring the ratio of 232 Th to 230 Th. Both of these dating methods assume that the proportion of 230 Th to 232 Th is a constant during the period when the ...

Longshore drift from longshore current is a geological process that consists of the transportation of sediments (clay silt pebbles sand shingle) along a coast parallel to the shoreline which is dependent on oblique incoming wave direction. Oblique incoming wind squeezes water...
