Types of Volcanoes
This Volcano is the simplest type of volcano and has a bowl shaped crater at the summit.
What is a Cinder Cone?
This type of Stress pulls on Earth's crust, stretching the rock to make it thinner.
What is Tension?
This is short for primary waves.
What are P waves?
This is a wave produced by and earthquake or landslide.
What is a Tsunami?
Some of the energy released in earthquakes is in the form of this.
What are Seismic Waves?
This Volcano is the largest volcano, and is sometimes called a Stratovolcano.
What is a Composite Volcano?
This is a break of the rock in Earth's crust or mantle.
What is a Fault?
Seismic Waves begin here.
What is The Focus?
Tsunamis and this are around the Ring of Fire
What are Earthquakes and/or Volcanoes?
This lurches up into motion releasing a great amount of energy for earthquakes.
What is Stress?
This is a large and explosive volcano, and is bigger than a crater. It forms a huge bowl.
What is a Caldera?
This type of Stress squeezes a rock until it bends or breaks.
What is Compression?
These release vibrations that travel through Earth carrying energy released by various processes, such as earthquakes, ocean storms, and volcanic eruptions.
What are Seismic Waves?
Indonesia and Thailand have been hit by many of these.
What are Tsunami's?
These are measured in Magnitude and Folds.
What are Earthquakes?
This volcano is built entirely out of liquid lava flows and is very broad and flat.
What is a Shield Volcano?
Strike-Slip Faults are known as this type of Stress.
What is Shearing?
This is directly above the Earth's Focus
What is the Epicenter?
These cause a displacement of water and are a main cause of Tsunami's.
What is a Landslide?
These two states have a much higher risk of getting hit by an earthquake, because they are on the Ring of Fire
What is California and Alaska?
This volcano is formed by small masses of lava too think to flow very far. As it grows its outer surface cools and hardens, then shatters, spilling loose fragments down its sides.
What is a Lava Dome?
The Hanging Wall is above the Fault, and this is below the fault.
What is The Foot Wall?
These travel slower than P waves and they move the ground side to side or up and down.
What are S waves.
Tsunamis are caused by this and Landslides.
What is Ocean Floor Uplift?
A Magnitude 8 earthquake is how many times larger than a Magnitude 9 earthquake?
32 times greater
