1 Geohazard Landslide in NC
Eric Angat Teacher Landslides are caused by the force of gravity pulling on the rocks.

2 1. In what part of North Carolina are landslides most frequent
1. In what part of North Carolina are landslides most frequent? ( N-E-S-W) Landslides are most common in the Western part of NC due to the slopes of the Appalachian Mountains.

3 2. What usually causes the landslides in Western North Carolina?

4 3. What is frost wedging? Frost wedging can result to landslide!
Water expands by 9% when it freezes. The expansive force of frost break rocks into smaller fragments. This process is called frost wedging. Frost wedging can result to landslide!

5 http://www. goalfinder
Water expands by 9% when it freezes. This property enables it to break rocks

6 4. How does frost wedging work?
The freezing and thawing of water results to the breaking of rocks through wedging. https://www.youtube.com/watch?v=_XnCTcjNpuc

7 5. What are the fault lines that can result to an earthquake
in North Carolina? New Madrid fault, stretching to 150 miles, crossing parts of Arkansas, Illinois, Indiana, Kentucky, Mississippi, Missouri and Tennessee Charleston fault in South Carolina

8 What are landslides? What determines the state of the flow of a landslide? What is a soil creep? How are potential landslides detected? What are the consequences of landslides?

9 Landslide- downhill movement of rocks, soil, mud, and other debris.

10 7. What determines the speed of the flow of a landslide?
What are landslides? 7. What determines the speed of the flow of a landslide? 8. What is a soil creep? How are potential landslides detected? What are the consequences of landslides? Landslides are uncontrollable downhill flow of rocks, soil, mud, and other debris. It is determined by the types of materials ( rocks, soil, mud) and the angle of slope. A type of landslide or erosion that moves so slowly. Tilted utility post, bent trees, and cracks on walls and road. Delayed construction, obstructed roads, tsunami

11 steep cliffs at the top of a slope
Cracks on roads and walls.

12 Split trunks and stretched roots Tree bark scrapped off.
