Plate Boundaries
Earthquakes
Volcanoes
100
The thinnest most brittle layer of the Earth.
What is the crust?
100
The slow movement of continents over millions of years.
What is continental drift?
100
The type of boundary that usually causes earthquakes.
What is transform?
100
This is the point below ground where an earthquake starts.
What is the focus?
100
This is what we call molten rock above the Earth's surface.
What is lava?
200
The only liquid layer of the Earth.
What is the outer core?
200
Large pieces of the earth's crust seperated by boundaries are called this.
What are plates?
200
The type of boundary found between India and China.
What is convergent with mountain building?
200
This is the crack in the Earth's crust along which earthquakes happen.
What is a fault?
200
This is the area where molten rock collects under a volcano and pressure builds eventually resulting in an eruption.
What is a magma chamber?
300
The thickest layer of the Earth divided into three parts of hot molten rock.
What is the mantle?
300
This is the theory that explains how plates move.
What is plate tectonics?
300
This happens at divergent boundaries under the ocean and has formed the mid-Atlantic ridges.
What is seafloor spreading?
300
This is the point above ground where an earthquake is felt first and strongest.
What is the epicenter?
300
This is the opening through which magma escapes from the volcano.
What is a vent?
400
The upper mantle and lower crust fused together.
What is the lithosphere?
400
The plates float on top of the mantle and move because of convection currents in this, another name for middle mantle.
What is aesthenosphere?
400
This is the area around the pacific plate where most earthquakes and volcanoes occur.
What is the ring of fire?
400
This is the report generated by a machine that is designed to measure the magnitude of earthquakes.
What is a seismogram?
400
This type of volcano errupts slowly sending lava out in all directions which cools to form a broad mountain.
What is a shield volcano?
500
The two elements that make up the inner and outer core.
What is iron and nickel?
500
These are two pieces of evidence that continents were once together as one large continent called Pangea.
What is similar fossils on different continents and the fact that the continents seem to fit together like puzzle pieces.
500
This is the type of boundary that results in volcanoes.
What is convergent with subduction?
500
This is the scale used to measure the magnitude of an earthquake by measuring the strongest wave given off during the earthquake.
What is the Richter scale?
500
This type of volcanoe erupts violently throwing ash and cinder way up into the air and forming a mountain with steep sides.
What is a cinder cone?
