no continents occupied the Northern Hemisphere
Wegener's continental drift hypothesis stated that all the continents once joined together to form
one major supercontinent
two major supercontinents and three smaller continents

What measurement for earthquakes do scientists use most often today?
moment magnitude scale
Richter scale
seismic scale
What is a fault?
the place on Earth's surface where structures move during an earthquake
a fracture in Earth where movement has occurred
another name for an earthquake
Violent shaking from an earthquake can cause soil and rock on slopes to move and cause a
landslide
tsunami
fault
Liquefaction occurs when
large waves wash over coastal areas and destroy structures

What does Earth's crust and uppermost mantle form?
hydrosphere
asthenosphere
lithosphere
What is an earthquake's epicenter?
A spot halfway between the focus and the surface
the spot below the focus
the place on the surface directly above the focus
An earthquake's magnitude is a measure of the
size of surface waves it produces
