Earth Layers
Boundaries
Volcanoes
Earthquakes
100
The large super-continent that eventually broke into the continents as we know them today.
What is Pangaea?
100
This layer of the earth is completely liquid and is part of one of the 5 layers of the earth when the layers are categorized by physical properties.
What is the outer core?
100
This boundary occurs when two tectonic plates slide past each other.
What is a transform boundary?
100
This type of eruption has lava flows, where magma flows from the volcano.
What is a nonexplosive eruption?
100
Scientists use this to measure seismic waves
What is a sesimograph?
200
This is the layer of the earth that tectonic plates float on
What is the asthenosphere?
200
This is the 3rd physical layer of the Earth meaning literally "middle sphere"
What is the mesosphere?
200
This happens in divergent boundaries that have oceanic crust.
What is sea-floor spreading?
200
This word, meaning "little stones" in Italian, are pebble-like magma that hardened before they hit the ground.
What are Lapilli?
200
This is the center of the earthquake ON THE SURFACE.
What is the epicenter?
300
This movement caused by a the heating and cooling of magma occurs in the mantle and causes tectonic plates to move.
What is convection?
300
This is the outermost layer of the earth when the layers are being categorized by their compositions.
What is the crust?
300
This happens at convergent boundaries that both have continental crust.
What is a subduction zone?
300
These type of volcanos are built by layers of lava from nonexplosives.
What are shield volcanoes?
300
Waves sent out by an earthquake
What are seismic waves?
400
This scientist started the continental drift theory, which is caused by plate tectonics.
Who is Wegener?
400
This layer is completely solid and is the innermost layer of the earth.
What is the core?
400
This type of boundary occurs when two tectonic plates spread apart
What are divergent boundaries?
400
In this type of eruption, lots of hot ash and gases shoot out from the volcano.
What are explosive eruptions?
400
This is the center of the earthquake IN THE EARTH.
What is the focus?
500
Tectonic plates are made up of chunks of this earth layer.
What is the lithosphere?
500
This compositional layer is made up of the asthenosphere and the mesosphere.
What is the mantle?
500
This type of boundary occurs when two tectonic plates collide
What is a convergent boundary?
500
These types of volcanoes are also referred to stratovolcanoes.
What are composite volcanoes?
500
Stands for primary waves
What are P Waves?
