Is there a pattern to the locations of earthquakes and volcanoes around the globe?
No, earthquakes and volcanoes are random.
Yes, earthquakes and volcanoes usually occur near the boundaries of tectonic plates.
yes, earthquakes and volcanoes usually occur in the middle of tectonic plates.
No, earthquakes and volcanoes usually occur under water.
Most earthquakes tend to occur at which location?
The central regions of very large continents
Groups of islands farthest from any continents
The boundaries between continents and oceans
The steep slopes of the very oldest mountains
Tectonic plates:
can move towards each other
can move away from each other
can slide past each other
All of the above

Most geologists think that the movement of Earth's tectonic plates is caused by
the rotation of the Earth.
the Earth's magnetic field.
subduction.
convection currents.
Which layer of Earth flows slowly and causes the crust to move?
Crust
Mantle
Inner Core
Outer core
What is the correct order (starting from the surface) of Earth’s layers?
crust, outer core, inner core, mantle
mantle, outer core, inner core, crust
crust, mantle, outer core, inner core
outer core, inner core, crust, mantle
When tectonic plates slide against each other causing the earth to move.
Subduction means.....
one plate goes under another plate
two plates slide past each other
two plate collide and form folded mountains
Sea-floor spreading explains how.....
new crust is created at a divergent boundary
volcanoes are formed on continents
deep sea trenches are formed
