Humans have drilled into the surface of the upper mantle. Even our deepest drilling usually stays in the crust.


About 90% of earthquakes occur where tectonic plates collide, forming faults. Earthquakes at faults occur when the two moving tectonic plates become caught at one spot and pressure builds as the plates continue to try to move. When the snag between the plates releases, an earthquake occurs.
Questions might include the following:
  • Have any earthquakes occurred recently on the mountain?
  • When did the volcano erupt last, and when is it expected to erupt again?
  • Have any thermal scans of the magma chamber been conducted recently?
  • Has any bulging or surface changes appeared on the volcano recently?
  • Have any gases been released by the volcano recently?
The tremors felt by the person on the safety poster are probably the faster, less-damaging body seismic waves of the earthquake. These waves are faster than the more damaging surface waves. If people are far enough away from the focus of the earthquake, they may have time to seek safety when they feel the first body waves at their location.
Mechanical weathering occurs when rocks are broken down into smaller pieces physically. Lichen are responsible for biological weathering, so this is not the right answer. The small cracks in the rock’s surface are the clue. The rock expands and contracts due to the heating and cooling it gets from the sun. It will experience frost weathering during the times of year when the water that seeps into the cracks freezes and thaws.
