At A-level, sediment and particle analysis is one possible data source as part of a portfolio of evidence to help understand a range of physical processes (past and present) that have been operating in an area or region. In most instances, projects that link to sediment analysis for an NEA will be focused on coastal or glacial environments. There may also be opportunities to use evidence from a fluvial system as part of wider study of the hydrological system.
The shape of sedimentary particles is an important physical attribute that can provide information about the sedimentary history of a deposit or even the energy that was associated with a particular system when particles were laid down. Particle shape is complex. It may be related to: lithology, particle size, the mode of transport, transport energy and weathering.
