Plate Tectonics
Where two tectonic plates meet is called a boundary or this. Hint: it starts with a "f".
What is a fault?
This part of an earthquake in the point below ground where the earthquake originates.
What is the focus?
The study of earthquakes is called this.
What is seismology?
The Circum Pacific Belt or this, is a region where about 80% of earthquakes occur.
What is the Ring of Fire?
The largest earthquake in history occurred in this country in 1960. Kudos if you know it's magnitude.
What is Chilie?
9.5 Magnitude
This boundary in the state of California is the site of much tectonic activity.
What is the San Andrea's Fault?
This earthquake part is the point on the earth's crust directly above the position underground where the earthquake started.
What is the epicenter?
Earthquake tracking centers use these graphs which record the energy waves from an earthquake.
What are seismographs or seismograms?
There are approximately this many earthquakes per year. However, only those around a magnitude of 3.5 can be felt by humans.
What is one million?
Buildings and bridges in earthquake prone areas are built to do this instead of break.
What is sway? I'll even take move.
When a tectonic shift happens under the ocean, one of these may develop.
What is a tsunami?
Earthquakes release a lot of this in the form of waves. Hint: It starts with an "e".
What is energy?
These earthquake waves travel the fastest and can travel through both solids and liquids.
What are primary waves or P waves?
The seconds delay between the arrival of these waves tells scientists how far away an earthquake started.
What are P and S waves?
This type of map gives the altitude and shape of various geographic structures.
What is a topograhpic map?
A huge earthquake in 1906 destroyed this California city.
What is San Francisco?
In general, the most powerful earthquakes occur at this type of movement boundary. Hint: The duck in the submarine.
These earthquake waves move the second fastest. They can only go through solids.
What are secondary, shear, or S waves?
These waves, sometime referred to as Love waves and Rayleigh waves, move along the "surface" of the earth causing damage.
What are surface waves?
These imaginary horizontal lines divide the earth into a northern and southern hemispheres.
What is latitude?
Plates can be described by how they move. These are the are the 4 types of plates based on movement.
What are convergent, divergent, transform, and subduction?
These releases of energy happen either before or after the actual earthquake.
What are foreshocks and aftershocks?
The mathematical term used to describe that information from at least 3 earthquake tracking stations must be used to find the origin of an earthquake.
What is triangulation?
This earthquake measuring scale is logarithmic, meaning that each number represents a 10 times increase in the magnitude of the earthquake. Hint: not Richter
What is the Modified Mercalli Intesity Scale?
These imaginary vertical lines divide the earth into an eastern and western hemisphere.
What is longitude?
