2The Different Types of Weathering The MAIN causes of erosion are; Erosion occurs when rock is washed, blown, or carried awayWeathering occurs when rock is broken down but stays in one place.The MAIN causes of erosion are;Running waterWindWavesGlaciers
3Grand Canyon: Rock layers formed and then were worn away by running water.
4In this picture the running water eroded rock, forming a canyon.
5The ground has been washed away by water. That is erosion.
6The water is creating erosion The water is creating erosion. The water is breaking up the soil and carrying it away. What did the power of running water create in this picture?
7Water erosion has taken this soil away and created gullies.
9These rocks have been blasted by wind and sand causing them to become rounded. WIND ABRASION
10Over great time, weathering from wind and running water caused these formations.
11Arches National Park was created when softer rocks weathered due to wind and rain and tough rocks on top were left behind forming huge arches and pillars. The sediment or rock bits we carried away leaving the empty space.
12Wave Action ; when waves hit the rocks and pieces of rock break off Wave Action ; when waves hit the rocks and pieces of rock break off. This is what causes shorelines to erode and creates beaches.
13Weathering from waves and tides made this arch. Can you make a hypothesis about what this coastline looked like millions of years ago? Can you predict what this coastline will look like in the future? Why?
14Weathering cause by tides and waves on the coast line.
15ErosionThe first five pictures of this presentation are of the same rock, just in different time periods. Pay attention to the dates on the side of the pictures and see what the water did to this rock.1890
