3. SEDIMENTATION
1º ESO A
Process for which the solid material transported by a water current settles at the back of a river , reservoir or artificial channel
The sea accumulates the sediments, contributing to the shape of the landscape. In this way beaches are formed.

4. EROSION
1º ESO A
Degradation and the transport of the material or substances of the soil.

Water
Fluvial erosion
When the slopes are gentler, the water moves more slowly.
It transports the eroded materials
When the rivers arrive at the platter lands , they deposit sediment on their banks .

8. Waves and currents wear away coasts and create cliffs .

Water
Marine erosion
Waves 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 A
Temperature
Temperature erosion
Abrupt changes in temperature can break rocks.
Water infiltrates through rocks. When it freezes, it expands, and the rocks break.
