Document Summary
Stony desert: northwestern kenya, pebbles, basalt lava composition, bedrock underneath from which they are derived is basalt lava, comes from close to lake turkana in kenya. Geologic hazards of natural origin and the role of people. Role of people is to accentuate the problem caused by natural processes. Want to minimize risk to life and property form hazardous conditions arising out of natural processes. Wind action, streams, ice action, marine processes, mass movement. Mass movement means movement of materials down slope, under influence of gravity and their own mass. Mass movement occurs in all conceivable natural environments. Water and mass movement are important related to damage that they cause to people: important for earthquakes and volcanic activity. Engineers use to attempt to make best decisions. Interested in analyzing possible solutions and thinking about what might go wrong. Geologic cycle (at least the surface part) From high to low pressure: air movement, from one extreme to another.
