• mitigate

• resilience

• viscosity

• fault

The ability to recover quickly from difficulties; toughness

• mitigate

• resilience

• viscosity

• plate boundary

Type of seismic wave which causes particles in the ground to move in a push-pull motion similar to a coiled spring

• surface wave

• secondary wave

• earthquake

• primary wave

A crack or fracture in Earth’s lithosphere along which movement occurs

• mid-ocean ridge

• plate boundary

• fault

• seafloor spreading

Type of seismic wave that causes particles in the ground to move up and down in a rolling motion

• primary wave

• surface wave

• secondary wave

• viscosity

Location inside Earth where seismic waves originate and rocks first move along a fault and from which seismic waves originate
