Define erosion? 1,2 A stream slows down and deposits sediment over time. How does an alluvial fan form? 1,3 Acidic water dissolves rocks underwater to form a cavern. How might erosion by groundwater create a landform? 1,4 A cave or a chamber in a cave. What is a cavern? 1,5 Running Water What cause a Valley to form? 2,1 Where the river enters the ocean. Where is a delta formed? 2,2 It moves rocks above ground where it is exposed to wind and rain. How does the gopher tortoise cause physical weathering? 2,3 Water that is below the Earth’s surface What is groundwater? 2,4 Where land and a body of water meet. What is shoreline? 2,5 Forms good soil for faming Why is Loess valuable? 3,1 Dust blown by wind making layers of dust build up. How is Loess formed? 3,2 Underground cavern What landform is mainly created by erosion by groundwater? 3,3 Plant roots and ice What causes cracks in rocks to grow larger? 3,4 Wind What mainly causes sand dunes? 3,5 Water speed and erosion increase What would happen if the slope of a stream was increased? 4,1 Gravity What force mainly causes landslides, rock falls, and mudslides? 4,2 Rain What weather condition mainly causes landslides, rock falls, and mudslides? 4,3 Release acid into soil increasing chemical weathering. How do decaying leaves affect rocks in the soil? 4,4 Melting ice blocks and Sediment What is needed for kettle lakes to form? 4,5 Cave What landform most likely formed beneath a sinkhole? 5,1 Mass movement caused by gravity Define Creep. 5,2 River water slowing down as it enter the ocean What causes the deposition of sand at a delta? 5,3 Marble What type of rock is most affected by acids? 5,4 A shape change due to exposure to wind/a change in size Define abrasion. 5,5
