The Earth's Layers
The outermost layer of the Earth
What is the crust?
The Earth is divided into many of these
What are plates?
Earthquakes happen most often near these
What are faults?
This volcano probably will not erupt again
What are extinct volcanoes?
Hot molten rock under the earth
What is magma?
The second layer of the Earth
What is the mantle?
Plates float on top of this
What is the mantle?
Bonus points if you mentioned convection currents!
This scale ranks earthquakes on magnitude
What is the Richter Scale?
The tunnel that moves the magma from the magma chamber to the outside world
What is a conduit?
These boundaries collide
What are convergent boundaries?
A liquid layer made of mostly iron and nickel
What is the outer core?
Where two plates meet
What is a plate boundary?
The most violent earthquakes occur at this boundary
What are transform boundaries?
These volcanoes have a broad base and lava gently oozes from them
What are shield volcanoes?
This layer makes the magnetic field that protects us from solar waves
What is the outer core?
The crust and upper mantle
What is the lithosphere?
This boundary causes earthquakes
Hint: there can be more than one
What are convergent, divergent, and transform boundaries?
These are how magnitude is measured
What are seismic waves?
If you misinterpreted the question and answered seismograph, that's okay too.
A hill that is formed by a pocket of magma under the earth
What is a laccolith?
The strongest earthquakes' magnitude and where it was located
What is the asthenosphere?
This boundary causes a reverse fault
What are convergent boundaries?
This scale ranks earthquakes not by magnitude, but by observable damage
What is the Mercalli Scale?
The volcano that spews hardened ash and lava and has a small crater
What are composite volcanoes?
Fun fact: Composite volcanoes can be up to 10,000 feet tall, while cinder cone are normally only 1,000
These waves are also called Lg waves
What are surface waves?
