3 SEDIMENTATION1º ESO AProcess for which the solid material transported by a water current settles at the back of a river , reservoir or artificial channelThe sea accumulates the sediments, contributing to the shape of the landscape. In this way beaches are formed.
4 EROSION1º ESO ADegradation and the transport of the material or substances of the soil.

7 When the slopes are gentler, the water moves more slowly. Causes of erosion1º ESO AWaterFluvial erosionWhen the slopes are gentler, the water moves more slowly.It transports the eroded materialsWhen the rivers arrive at the platter lands , they deposit sediment on their banks .
8 Waves and currents wear away coasts and create cliffs . Causes of erosion1º ESO AWaterMarine erosionWaves and currents wear away coasts and create cliffs .Water transports the sediments , deposits it , and forms beaches.
9 Causes of erosion Temperature erosion 1º ESO ATemperatureTemperature erosionAbrupt changes in temperature can break rocks.Water infiltrates through rocks. When it freezes, it expands, and the rocks break.
