QUESTIONS | WITH COMPLETE SOLUTIONS.

When the waves reach the surface of the water, they spread outward
, - Moderate slopes are associated with flows
- Gentle slopes are associated with creep
Approach the land, sea floor changes
As the tsunami approaches land, the water depth decreases
This results in the water ' piling up' and causes these effects:
Due to human behaviour
We need ozone to protect us from sun rays
The ozone layer (25km above the surface)

The theory proposes that three separate phenomena relating to Earth's orbit
lead to climate change. They are referred to as the three Milankovitch Cycles:
1. Eccentricity
2. Precession
3. Obliquity
Even if we could make the technology 100% reliable, the overall system reliability
would be 75%
(from previous example)
(1.00 x 0.75 = 0.75)
- Human reliability brings down reliability significantly
, Grading of land surfaces for a new home and building construction can increase
probability of slope failure.
- high risk, wet climate, high slopes
Harvesting timber and urbanization are currently the leading human causes for
increase in landslides.
- Tornado: 22%
- Blizzard: 74% have people high and low on graph, little knowledge about
this
- Hurricane and Tornado: low chance, people agree
- Hurricanes have higher probability, have never had a tornado

Water saturates soil, increasing the likelihood of flows.
Following prolonged periods of deep water infiltration, slumps can develop
Slumps become problem after lots of rain
Water can also erode the base of a slope therefore decreasing it's resisting force
- current mountain ranges
- puzzle piece shapes
- Pangaea
- earthquakes match up with plate boundaries
, - sometimes we see earthquakes in ON, even though we are far from plate
boundary
- volcanoes also line up with boundaries
- According to Consumers Union study, eating peanut butter (which contains an
average level of 2 parts per billion of aflatoxin) once every 10 days presents a
cancer risk of 7 in one million
- Small as it may seem, it is higher than the estimated risk of cancer from most
pesticides
-This risk is higher than that of pesticides but we don't hear about it
Nature of Motion:
1. Flow
- rock avalanche;
- fast velocity
2. Slide or Fall
- stump, rockslide, rockfall;
- slow to moderate to fast velocity
3. Flow
- earth creep, earth flow, debris flow and mudflow;
- slow, slow/ moderate, 2 moderate velocity
4. Slide or Fall
- stump, debris slide, debris avalanche;
- slow/ moderate, moderate/ fast, fast
