False
People can feel every earthquake that happens
Divergent Boundary
A plate boundary where two plates move away from each other.
Convergent Boundary

Wegener’s evidence for continental drift includes…
Transform Boundary
A plate boundary where two plates move past each other in opposite directions
Subduction
The sinking of one lithospheric plate under another lithospheric plate is known as:
Seismic Waves

Aftershocks
Following an earthquake small tremors known as ______ can occur, lasting for hours to days after the original quake
Earthquake
Happen when a plate scrapes, bumps, or drags along another plate
Pangaea
The name given to the ancient supercontinent
Magnetic Patterns (stirpes)
One of the main pieces of evidence for Sea-Floor Spreading
Why was Wegener’s hypothesis of a supercontinent that broke apart rejected?
He could not tell how the continents moved.
