- a volcano that has not erupted in thousands of years
- seismic waves that vibrate back and forth
- a scientist who studies earthquakes
- the giant land mass that once contained all the present continents
- rock formed from igneous or sedimentary rock that has been subjected to extreme heat and pressure over time.
- a mixture of broken down rocks and the remains of living things that are carried by wind, water or glaciers

Down
- an instrument to record seismic waves
- carrying away of tiny rock particles and soil by wind, water, ice or just plain gravity.
- rock formed by cooling and solidifying of magma
- seismic waves that move along the Earth’s surface
- magma that flows on the earth's surface in a volcanic eruption
- a scale for the magnitude of an earthquake based on the damage caused
- igneous rock that cools and hardens inside the earth’s crust
- igneous rock that cools and hardens outside the earth’s crust
- the point inside the Earth’s surface where an earthquake begins
- The movement of solid "plates" that make up the crust of the earth.
- non-living; not formed by living things
- a crack or fracture in rock along which movement can occur
- Rock formed from sediments that are compacted (=pressed) and cemented together.
- the point on the Earth’s surface directly above the focus of an earthquake
- molten rock beneath the surface of the earth
