Which of these provides the best evidence that Earth’s crust is divided into tectonic plates?

• the distribution of water on Earth’s surface
• the distribution of biomes on Earth’s surface
• the distribution of rock types on Earth’s surface
• the distribution of earthquakes on Earth’s surface

Tectonic motion caused tension between plates in Earth’s crust. A sudden release of this energy occurred. Based on this information, which event happened?

• Subsidence
• Earthquake
• Volcanic eruption
• Meteoroid impact

Which ongoing process causes the buildup of energy that is released at a later time when an earthquake occurs?

• Heat from Earth’s core slowly melts the rocks found deep in Earth’s crust.
• Nuclear reactions in Earth’s lower crust release electromagnetic waves.
• Jagged edges along a fault generate friction between two moving tectonic plates.
• Tectonic plates near a fault continue to move even though the fault remains motionless.

In the 1960s, seismometers were installed around the world for the purpose of monitoring nuclear testing. The seismometers unexpectedly showed that most of the world’s earthquakes and volcanoes occurred in belts along the continental margins. How did these new data help support the theory of plate tectonics?

• by allowing scientists to prevent future volcanoes near tectonic plate boundaries
• by providing evidence the continents have moved extensively over time
• by providing evidence of interactions between moving tectonic plates
• by allowing scientists to predict where future earthquakes would occur
