1. What conditions might cause mud to flow?
The conditions that might cause mud to flow is a steep slope and/or wet soil.
2. What conclusion can you draw from the two images?
I concluded from the two images that the steeper the slope, the better chance of a mudflow. I also noticed that even if you have the smallest change in slope, it can still create a mudflow.
3. List at least two ways you could make the mud slide off the 30° slide plane without changing the plane's angle.
One way to create a mudflow off the 30 degree slope is to add more water to the soil. Another way is to make the slope more slippery.
4. What conditions in nature would be represented by the answers you gave for question 3?
More rain with a slippery clay surface that the soil could be still on.
5. List at least two factors that contribute to the formation of mudflows on volcanoes.
A sudden release of water from a nearby glacier, and the quantity of loose debris such as ash.
6. How might forest fires affect an area's potential for experiencing mudflows?
It burns the forests and brush which creates a flat burned surface.
7. Hypothesize about how mudflows could change the topography of an area after a fire.
I hypothesize that it would cover the burned material on the surface and cover it making it seem like the fire never happened.
8. What human activities strip soil of its protective vegetation and increase its vulnerability to mudflows?
Logging removes trees from the landscape and construction.
9. Write a paragraph describing the conditions that cause dangerous mudflows. Include the types of locations where mudslides are most likely to occur.
The conditions that are needed to create a dangerous mudslide are, loose soil, water, a steep slope, and vegetation but not a lot of it. Loose soil so that it doesn't take much for the mudslide to begin, water because it also helps the slide to move faster. A steep slope so that gravity is a big factor when the mudslide begins. Not a lot of vegetation because the roots aren't attached into the ground anymore.
