Waves usually reach the shore at an (a), this is because of the (b) direction, because of this sand is moved up the beach by the (c) of the wave at an angle. The (d) carries the material directly back down the beach due to gravity. This process is repeated producing a (e) pattern which moves sand along the shore by a steady current. People have built wooden groynes to stop this movement and widen the beach. Unfortunately this can starve beaches further along the coast of fresh sand leading to increased e(f). .Where the coast changes direction suddenly the sand is deposited out to sea producing a (g) such as Spurn Head.

Sedimentary rock formation occurs when igneous, metamorphic, or other sedimentary rocks are exposed to the unyielding forces of nature found on the earth's surface. the formation of sedimentary rock occurs by several processes over millions of years. when rock sediments are deposited, an increase in weight causes pressure to increase which leads to the compaction of the rock particles. water is pushed out and cementation occurs as dissolved minerals are deposited in the very small spaces between the rock sediments acting as glue that binds the sediments together. which process describes the changing of sediments into rock by compaction and cementation? a) deposition b) lithification c) physical weathering d) chemical weathering
