What is the difference between the epicenter and the focus of an earthquake?
The focus is the underground point where an earthquake starts releasing energy, while the epicenter is the spot on earth's surface directly above the focus.
400
What is the Ring of Fire?
A string of volcanoes surrounding the pacific ocean and on tectonic plate boundaries.
400
How is an earthquake defined?
any kind of shaking of the ground measurable by seismic instruments.
400

Secondary Waves
400
The stress force that pushes the two pieces of crust/pieces together is called…
Compression Stress
500
Why do scientists say they can’t predict earthquakes, but they can forecast them?
Because of the unpredictable shaking, they can calculate how large they can be.
500
Why are some places on Earth more likely to have earthquakes than others?
Most seismic activity is concentrated along tectonic plate boundaries.

Why are some places on Earth more likely to have earthquakes than others?
Most seismic activity is concentrated along tectonic plate boundaries.
500
Why do aftershocks happen after a big earthquake, and why can they last for days or even months?
Aftershock can last so long because the stressed rock has to have time to settle and reach a new equilibrium.

How does a tsunami form from an earthquake?
When an earthquake forms from underwater, the waves from the earthquake form water waves causing a tsunami.
