types of mass movement
- soil creep
- slow movement of soil down a slope due to gravity
- slowest type of mass movement - 1-2 cm per year
- Evidence of soil creep
- Trees grow at an angle.
- Terracettes form, these
are small steps of
accumulated soil.
- Fences bend.
- Walls crack

- bog burst
- mud flow
- fast moving river of rock, soil and
water down a slope.
- Fast moving. the amount or water and
the angle of the slope determine the
speed up to 100kmp/h.
- Usually happens after periods o heavy
rainfall

- land slide
- avalanche
- An avalanche is a
rapid movement of
snow and ice down a
slope.
- Small controlled explosions are
used in the alps to cause small
avalanches, and thereby prevent
large avalanches.

- River of mud when ash from a
volcano mixes with melting
snow.
- Example Nevada del Ruiz
- 23,000 killed
