Deposition Deposition is the dropping, or depositing, of sediments by water, wind, or ice. It builds new land on Earth’s surface, like a delta at the end of a river or the pile up of a sand dune in the desert. Shells on the beach are deposition by ocean waves. Deposition begins with a and Dunes and Deltas begin with a “D” “D”. Chant: Weathering will break rocks down Erosion moves it all around Put it here and then done we’re Now we have deposition Landslides Landslides are mass movements of land due to gravity. Landslides can cause buildings to fall, or power and gas lines to break. Landslides even occur on the continental slope in the ocean. Volcanic eruptions Volcanoes are mountains with openings in crust through which magma, gases, and Earth’s ash reach surface. Earth’s When the magma erupts from the volcano the top of the mountain can be changed, either built up or exploded off. The lava and ash can destroy forests and bury fields. Volcanic eruptions can even change weather patterns. Earth’s Volcanic eruptions also occur under the oceans; these volcanoes that are built up are called If the seamount rises above the ocean surface it is called a (for example Seamounts. volcanic island Hawaii or Japan). Earthquakes Earthquakes are vibrations on surface caused by sudden movement in the Earth, often Earth’s along a fault, a break in surface. Earth’s Some earthquakes cause little damage and some cause a lot of damage. Large earthquakes can cause landslides. Earthquakes under the ocean can cause huge waves, called that destroy land and tsunamis cause great damage if they come ashore. Floods Floods occur when a large amount of water covers land that is usually dry. When the flood occurs; rapid erosion can take place and move soil and sediments away. When the flood recedes; new sediment is left behind and can build up rich soil deposits.
