Erosion / Deposition
The Geology Book
- Law of disintegration
- List and describe the five main causes of erosion. How many types of erosion can you observe happening around where you live?
- Research various large hurricanes that have happened in the past few years. How much damage did each one do?
- Describe the rapid erosive processes (three are discussed).
- What is a “delta?”
- How is a turbidite formed?
- What causes a tidal wave (tsunami)?
This is week 2 of the experiment started in the last lesson. Has your mound decreased any? What caused this decrease?
- Rain; Ice; Plants and animals; chemicals; ocean waves
- Allow students to do their own research.
- Cavitation occurs when tiny bubbles in moving water explode inwardly; plucking is where rocks are picked up by moving water; kolk is like an under-water tornado that breaks up rock.
- Slowing water from a river into a larger body of water deposits its sediments onto the sea floor
- First, an event such as an earthquake starts a mud flow underwater. Next the mud flow spreads out. Eventually the mud flow hardens into a layer of rock.
- An underwater earthquake or volcanic eruption causes a shock wave of energy to race through the water. As the wave nears the shoreline, it becomes a wall of water which slams into the shoreline.
