Loose material such as sand, gravel and pebbles that can be transported and deposited.

Two beaches might look different, but measurements allow you to describe precisely how their slopes or sediment differ.

Loose material, such as sand and shingle, that can be transported and deposited.

Loose material, such as sand, shingle or silt, that can be transported and deposited by water.

Waves and currents also move sediment and deposit it elsewhere, building beaches, spits and bars. Sediment includes loose sand, shingle and finer particles. It can reach the coast from eroding cliffs, rivers or neighbouring stretches of shoreline.

Solid material, such as clay, sand, pebbles and boulders, carried or deposited by a river.

Loose material such as sand, gravel and pebbles deposited on a beach.

Distinguish sediment size, measured in millimetres, from roundness, judged using categories.

Link deposition to reduced energy and the dropping of sediment, rather than simply stating that waves reach the shore.

Explain limitations specifically. For example, selecting only large pebbles biases the sediment sample, so use a consistent sampling rule.
