Miscellaneous
Caused due to the displacement of energy on the ocean floor, usually an earthquake.
What is a tsunami?
This is the location on the surface directly above the focus.
What is the Epicenter?
Tension, Compression, and Shearing are examples of this.
What is Stress?
Country with the most earthquakes
What is Indonesia?
This type of volcano is cone shaped, tall, and produces explosive eruptions.
What is a Composite volcano?
In 1883, one of the most deadly and explosive eruptions occurred due to this volcano.
What is Krakatoa?
The point within the Earth where an earthquake starts.
What is the focus?
This is the study of earthquakes.
What is seismology?
This type of fault creates tension between the land.
What is a normal fault?
Made almost entirely out of liquid lava flows, this volcano has lava coming from every side from a vent making a flat, broad lava cone.
What is a shield volcano?
These waves can travel through solids, liquids, and gases and have the greatest velocity out any other wave.
What are Primary (P) Waves?
Formed when tension forces rocks to drop down relative to other rocks.
This is when the rock bend down on the other side of the axis.
What is an Anticline?
This occurs when a reverse fault makes one block of land move above the other one.
What is Compression?
This volcano has a bowl shaped crater and forms from particles and solidified lava blobs. Deemed the simplest type of volcano.
What is a cinder cone?
These are made from compression and folding of Earth's crust due to tectonic plate collisions.
What are Folded Mountains?
It defines the measure and earthquake size and doesn't change with distance. Intensity describes how much it shakes at a given location.
What is the difference between Magnitude and intensity?
These are fractures on the Earth where movement has occured.
What are faults?
For example, if a normal fault were to occur, this would be the block moving while the other stays still.
What is a hanging wall?
Formed by small masses of lava that build up over time to form a bulge.
What is a Lava Dome?
A volcanic ring scattered with volcanoes and earthquakes, that surrounds most of the Pacific Ocean.
What is The Ring of Fire?
Used to record seismic waves from earthquakes with sensore to detect motion, and then convert into electrical signals.
What is a Seismograph?
This state has a high frequency of earthquakes.
What is Alaska?
This occurs when two pieces of land rub horizontally against each other.
What is a strike slip fault?
Largest and most explosive type of volcano. Some examples include Aniakchak in Alaska, and Chaiten in Chile
What is a Caldera?
