Tectonics
The layers of the earth
What is crust, mantle, outer and inner core?
A depositional mountain built up by molten rock that has risen to the earth's surface through a vent.
What is a volcano?
An instrument that simply detects earthquakes
What is a seismometer?
An ocean wave caused by an earthquake
What is a tsunami?
Magma that reaches the surface
What is lava?
Includes the crust and upper mantle that are made of rigid, brittle rock plates that move.
What is lithosphere?
The most common type of structure for volcanoes
What is stratovolcano?
The three types of waves measured in an earth quake
What is p-waves, s-waves, and surface waves
The measure of resistance of a liquid to flow
What is viscosity
When would a typical young-earth creation geologist say volcanoes formed?
What is the flood?
The process by which thinner crust slowly slides down and under more massive thicker crust.
What is subduction?
What is igneous?
Crack within earths rocky crust where rock has been fractured
what is a fault?
Also called a composite cone; can have slow or violent eruptions; Formed from alternating layers of ash and lava
What is stratovolcano?
The simplest type of volcano with sudden violent eruptions; formed from volcanic cinders
What is Cinder cone?
Heat from the core of earth causes this to occur in the mantle. There is constant heating then cooling.
What is convection currents?
The three levels of activity for volcanoes
What are active, dormant, extinct?
the point on earths surface directly above the location of an earthquake
What is epicenter?
a Way of measuring the strength of earthquakes using a logarithmic scale
What is Richter Scale?
What is divergent plate boundary
The motion of oceanic tectonic plates away from mic-oceanic ridges where mantle rocks rise to form new ocean crust.
What is seafloor spreading?
The type of magma is controlled by two things
Secondary, smaller earthquakes that result from a major earthquake
What are aftershocks?
When tectonic plates move towards each other
What is convergent plate boundary?
A 5 layer list made by creationists that explains the rock layers seen today
What is diluvial geologic column
