Erosion and Deposition CHAPTER NEW CHAPTER Erosion and Deposition the BIG idea Water, wind, and ice shape Earth’s surface. 5.1 Forces wear down and build up Earth’s surface. 5.2 Moving water shapes land. 5.3 Waves and wind shape land. 5.4 Glaciers carve land and move sediments. CHAPTER OUTLINE CHAPTER RESOURCES

5.1 Forces wear down and build up Earth’s surface. Water, wind, and ice move sediment in the process called erosion. erosion deposition mass wasting CHAPTER RESOURCES SECTION OUTLINE

5.1 Forces wear down and build up Earth’s surface. Water, wind, and ice move sediment in the process called erosion. The placement of sediment in a new location is deposition, part of the erosion process. erosion deposition mass wasting CHAPTER RESOURCES SECTION OUTLINE

Moving water shapes land. 5.2 Moving water shapes land. Water drains from land in drainage basins, which are separated by divides. drainage basin divide floodplain alluvial fan delta sinkhole CHAPTER RESOURCES SECTION OUTLINE

Moving water shapes land. 5.2 Moving water shapes land. Water drains from land in drainage basins, which are separated by divides. As water flows over land and underground, it moves sediment and changes land features. drainage basin divide floodplain alluvial fan delta sinkhole oxbow lakes meanders CHAPTER RESOURCES SECTION OUTLINE

Waves and wind shape land. 5.3 Waves and wind shape land. The action of water moves sand and builds up new landforms, such as sandbars and barrier islands. longshore drift Incoming waves push sand up the beach at an angle. The sand washes back straight down the beach. longshore current 2 1 wave direction longshore current sandbar barrier island dune loess CHAPTER RESOURCES SECTION OUTLINE

Waves and wind shape land. 5.3 Waves and wind shape land. The action of water moves sand and builds up new landforms, such as sandbars and barrier islands. longshore drift longshore current sandbar As more sand is deposited, the sandbar rises above the surface to become a barrier island. Waves and currents move and build up sand deposits to form a sandbar under the water surface. barrier island dune loess CHAPTER RESOURCES SECTION OUTLINE

Waves and wind shape land. 5.3 Waves and wind shape land. The action of water moves sand and builds up new landforms, such as sandbars and barrier islands. longshore drift Wind forms dunes. longshore current Wind makes sand particles build up and tumble down, causing a dune to migrate, or move. wind sand-particle movement dune movement sandbar barrier island dune loess CHAPTER RESOURCES SECTION OUTLINE

Glaciers carve land and move sediments. 5.4 Glaciers carve land and move sediments. Glaciers are large bodies of ice glacier till moraine kettle lake CHAPTER RESOURCES SECTION OUTLINE

Glaciers carve land and move sediments. 5.4 Glaciers carve land and move sediments. Glaciers are large bodies of ice that change landscapes as they move. glacier till moraine kettle lake CHAPTER RESOURCES SECTION OUTLINE
