Weight of potential failure block Angle of internal friction Angle of potential failure plane Water content None of the above, they all increase it

Gypsum Halite Potash Limestone Chert
If a litre of sea water is evaporated, which of the following evaporites that precipitated will occur in the greatest amount? Gypsum Halite Potash Limestone Chert

In which of these settings would one most likely find a nuee ardente?
At the site of a fissure eruption At a constructive plate boundary In Hawaii At a destructive plate boundary At a transform plate boundary

How many earthquakes of Richter magnitude 5 would it take to equal the output of energy from a single earthquake of Richter magnitude 7? 2 30 60 900 27 000

In order to determine the seismic risk of an area, we need to determine the Richter magnitude of earthquakes that occur in that region. The Richter magnitude is determined by: Measuring the amount of movement on the fault that caused the earthquake Measuring the intensity of earthquake damage Measuring the length of time of the ground-shaking event Measuring the time between the first arrival of S waves and the first arrival of surface waves on the seismogram Measuring the amplitude of the seismic waves on a seismogram

For seismic P and S waves received by seismographs at various distances from an earthquake focus, a plot of first arrival times against distance would look like:

5 years 14 years 20 years 28 years 50 years
