100
A dangerous type of volcanic flow that contains ash and dust
What is pyroclastic flow
100
Lava that forms underneath water and forms rounded lumps
What is pillow lava
100
Seismic waves that travel on the inside of the earth
What are body waves
200
The top layer of the earth containing both crust and some small mantle.
What is the lithosphere
200
The place where a plate is broken
What is a fault.
200
The place below a volcano where eruptions begin
What is the magma chamber
200
Produced by non explosive eruptions.
What is lava
200
The lower part of the mantle above the outer core
What is the mesosphere?
300
The chemical layer that contains molten rock and flows slowly
What is the mantle
300
The total number of tectonic plates
What is 10
300
Opening in the Earth's crust
What is a vent
300
Lava that is thin and flexible and flows in wrinkles
What is pahoehoe
300
Waves that are weak and slow but cause the most damage

400
The physical layer of the earth that tectonic plates float upon
What is asthenosphere
400
The place where two tectonic plates collide
What is convergent boundary
400
The most common type of eruption that involves lava flow
What is nonexplosive eruption
400
Lava that forms a thick brittle crust with sharp edges
What is Aa lava.
400
The change in the shape of a rock in response to stress.
What is deformation
500
The chemical layer of the earth made of mostly iron and nickel
What is the core
500
The place where two tectonic plates slide past one another
What is transform boundary
500
The amount of this compound makes magma thick and stiff and may cause a blockage that causes the buildup of pressure leading to eruptions.
What is silica
500
Cool stiff lava that does not travel very far and contains sharp edges
