2  A landslide is when a chunk of earth falls down a steep slope  it can be made of dirt, rocks or debris

3  Landslide can occur anywhere there is a slope and unsound land  They tend to happen where there are frequent earthquakes, hurricanes, tsunamis, or even heavy raining

4

5 Landslide tend to happen when there is more rain. They don’t typicly happen in the winter due to the earth being frozen with frost (but that does not mean they cant happen)

6  Landslides affect many different thing as in…  Buildings on or near the hill  Gardens  Houses  The hill itself  Any forest nearby

7  During a landslide there are some things that always happen  The land tends to fold up first  Then is starts to fall  It can happen slowly or very fast  There are 4 kinds of landslides  Mudflow, slump, debris flow, and rockslide

8

9  The most extreme conditions would be…  The whole side of the mountain collapses  It moves faster than a car  The width of it is bigger than 3 cars

10  Landslides have no official scale so they are measured by…  How many metric tons fell  How deep they are  How far they traveled

11  Tsunamis (if it falls in a lake)  The hill may be completely destroyed  It will wipe out any forest nearby  It could break a dam causing floods

12  a metric ton = 2204.62262  A tsunami is a giant wave  Mudflow: a landslide made of mud  Slump: when it all falls at once  Debris flow: made of gravel, wood, or anything that’s not dirt or rock  Rock fall: rocks falling at high speeds
