Mechanical Weathering and Erosion Lab

Mechanical Weathering and Erosion Lab. Review. Station #1 Wind Erosion. The wind would transport the sand to a new location. The sand would probably stick to the clay, adding material to the landform. Over long time period the wind blown sand would reshape other landforms.

  1. Mechanical Weatheringand Erosion Lab Review

  2. Station #1 Wind Erosion • The wind would transport the sand to a new location. • The sand would probably stick to the clay, adding material to the landform. • Over long time period the wind blown sand would reshape other landforms. • Both use moving sand to physically reshape an object.

  3. Station # 2 Splash Erosion • Mountains that experience large amounts of rainfall would be worn down more rapidly. • Some material is less resistant to weathering, so it would break down more quickly. 3.The water dropped from a greater height moved the material faster. It also moved the larger pebbles further away from the landform.

  4. Station # 3 Dissolving Rock • As the water slowed down the sugar settled out of the water. (deposition) • The surface of the “rock” was weathered and eroded. • The rock is carried towards the bottom of the tray. When the water evaporates the sugar is left behind. Stalagmites and stalactites are formed in a similar way.

  5. Station #4 Mechanical Weathering • Rock fall, Landslide, Saltation Abrasion

  6. Station #5 • Answers will vary • Magnetite

  7. Station # 6 Wave Erosion Wave Erosion of Coastal Cliffs Animation

  8. Station # 7 Preventing Erosion • The plant would help hold the soil in place. • Water moving at a greater velocity will carry (erode) more sediment. • Parking lots, roads and paved driveways allow running water to pick up speed before coming in contact with soil, which will increase erosion.

  9. Station # 8 Rates of Weathering • Rock B is more resistant to weathering. • Rock A is less resistant to weathering. • Drawing should show that rock A has been broken down into sediment. Most of the sediment would have been washed away. • Drawing should show the formation of a hoodoo. Rock B would have protected the portion of Rock A that was directly below it, forming a tower or a column. Hoodoo
