Volcanoes
What is a volcano?
A volcano is a vent in Earth's crust through which melted or molten rock flows.
What is an Earthquake?
The vibrations in the ground that result from movement along breaks in
Earth's lithosphere.
What is a plate boundary?
A plate boundary is the edge where two tectonic plates meet.
Is the Ring of fire a perfect circle?
No, the Ring of fire is NOT a perfect circle.
What is a seismic waves?
A rapid release of energy along a fault.
How many volcanoes did we learn about?
What is 4
Why do rocks move along a fault?
The forces that move tectonic plates also push and pull on rocks along the fault.
What happens at a divergent plate boundary?
When two plates spread apart along a divergent plate boundary.
What is the part of the world where most earthquakes and volcanoes occur?
The Ring Of Fire.
What do seismic waves do?
Seismic waves transfer energy through the ground and produce the motion that you feel during an earthquake.
What type of volcanoes are composite?
Composite volcanoes are large, steep-sided volcanoes that result from explosive eruptions of lava and ash along convergent plate boundaries.
What is a fault?
A fault is a break in Earth's lithosphere where one block of rock moves towards, away from, or past another.
What happens at convergent boundary's?
When two plates collide, the denser plate sinks, or sub ducts, into the mantle.
What ocean does the Ring of fire surround?
What is the Pacific ocean.
What is a seismonogist?
Scientists that study earthquakes.
What contributes to how explosive a volcano can be?
Dissolved gases.
What is an epicenter?
The epicenter is the location of Earth's surface directly above the Earthquakes focus.
Can volcanoes from at a divergent plate boundary?
Yes
What does the Ring of fire represent?
The Ring of fire represents an area of Earthquake and volcanic activity.
What are types of seismic waves?
Primary waves, secondary waves, surface waves.
What is the definition of Viscosity?
A liquid's resistance to flow
Whats another way to measure and describe an Earthquake?
Is to evaluate the damage that results from shaking.
How does the process at a convergent boundary form a volcano?
Two plates collide, the denser plate sinks, or subducts into the mantle.
What plate boundaries are the Ring of fire located on?
Divergent plate boundaries.
What is the difference between a seismometer and a seismogram?
Seismometer: records and measures ground motion and can be used to determine the distance seismic waves travel.
Seismogram: A graphical illustration of seismic waves.
