The Crust
What are the different peices of the Earth's crust called?
Tectonic Plates or Plates
What is the difference between Intensity and Magnitude?
Intensity = How it is felt in one location

What is it called when plates move away from each other and new rock fills in the gap? Hint: it causes volcanoes
Divergent Boundaries
What do you do if there is an earthquake where you are?
Stop, Drop, and Cover or get under something and cover your neck
Why is flexibility important for earthquake resistant buildings?
It allows them to move with the shaking
Afterquakes are smaller earthquakes that come after the initial shaking

What layer of the Earth is made of really really hot rock?
The Mantel
What is it called when two plates push really hard into each other? Hint: This kind of movement makes mountains

What scale going from 1 to 10 measures the Magnitude of an earthquake?
The Richter Scale
Why would you want a strong base for your tower?
If the base collapses, so does the rest of your tower
We experience earthquakes almost every day
True! although they are too small to feel, the Earths crust is constantly moving causing small tremors, or teeny tiny earthquakes we can't feel

71%
What kind of plate movements cause massive valleys and are responsible for moving the continents away from each other? Hint: There is a MASSIVE canyon in the middle of the Atlantic ocean caused by this.
Continental Rift
What machine in the exploratorium measures seismic activity? Hint: There is a word in this sentence that gives the answer away
seismograph
It has joints so it can move with an Earthquake
