The movement of the tectonic plates is caused by
the rotation of the Earth.
convection currents in the Asthenosphere
the gravity of the iron-nickel core.
the Moho discontinuity.
In some areas of the world, like California and Japan, earthquakes are a common occurrence. How can this best be explained?
The strong ocean currents are undermining both areas causing earthquakes.
Both areas are located near the edge of the Pacific Ocean, the unstable sand causes earthquakes.
Both areas are subjected to strong ocean wind and waves that causes earthquakes.
Both areas are on the boundary of active plates, the motion of the plates causes earthquakes.
The map in the picture shows tectonic plate boundaries. This map would be useful in predicting the location of future
droughts
hurricanes
earthquakes
tornadoes
