Weathering And Erosion
The Different Types of Weathering Erosion occurs when rock is washed, blown, or carried away Weathering occurs when rock is broken down but stays in one place. The MAIN causes of erosion are; • Running water • Wind • Waves • Glaciers
Grand Canyon: Rock layers formed and then were worn away by running water.
In this picture the running water eroded rock, forming a canyon.
The ground has been washed away by water. That is 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?
Water erosion has taken this soil away and created gullies.
These rocks have been blasted by wind and sand causing them to become rounded. WIND ABRASION
Over great time, weathering from wind and running water caused these formations.
Arches 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.
Wave Action ; when waves hit the rocks and pieces of rock break off. This is what causes shorelines to erode and creates beaches.
Weathering 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?
Weathering cause by tides and waves on the coast line.
Erosion The 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
Erosion Still the same rock. 1910
Erosion Still the same rock. 1920
Erosion Still the same rock. 1970
Erosion Still the same rock, but where did it go? 1990
This glacier is carving out a U shaped valley between these mountains.
This is a picture of a glacier which carves out a U-shaped valley where it flows dragging rocks and boulders along the way.
• Oxidation • Root Pry • Exfoliation • Frost Action (Freeze and Thaw) • Wind abrasion
This rock is red because of the oxidation of iron in the sediment when the rock was being formed.
Plant Roots
Root Pry
This is a picture of the Half Dome. The rock is peeling away from the mountain in layers just like an onion. This is exfoliation.
Dome Exfoliation
Freeze and Thaw
Frost Action or freeze and thaw slowly breaks up this sedimentary rock into unusual shapes.
Weathering from wind, rain, and freeze and thaw made Bryce Canyon.
