This map shows an area on Earth called: __________.

• Hot Spots

• The Ring of Earthquakes

• The Ring of Fire

• The African Plate

Why do earthquakes often cause damaging fires?

• Magma from deep underground escapes through faults.

• Tsunamis from earthquakes generate enough heat to start fires.

• Lightning strikes are common during earthquakes.

• Earthquake vibrations can break gas lines, water lines, and electrical lines.

Why are seismic waves of an earthquake more strongly felt at the epicenter of an earthquake?

• The epicenter is directly above the focus, the place inside the Earth where the earthquake starts.

• Most faults converge at the epicenter.

• Millions of small movements of the crust occur here.

• Crustal plates rise and fall with the ocean tides.

Why was magnetism so important in discovering plate tectonics?

• It illustrated the location of the South Pole.

• It allowed for the measuring of mountain building rates.

• It allowed for the depth of the ocean to be measured.

• It demonstrated sea floor spreading.
