Earthquakes
Thin zones of rock that are separating breaks in the Earth´s crust.
What are faults?
When rocks are heated and under intense pressure they liquify
What is molten rock?
When an earthquake happens underwater it causes this to happen
What is a Tsunami?
Magma cooling to solid form
What is igneous rock?
When rocks shift and release an enormous amount of energy after being stuck
What is the way an Earthquake happens?
Less dense than the solid rock of Earth's crust, this substance wants to rise to Earth's surface
What is Magma?
Valleys created by faults in the crust
What are fault valleys?
When igneous rock goes through weathering and lithification
What is sediment?
The spot on the fault where the pressure is first released
What is the hypocenter/focus?
A cone-shaped hill or mountain that is formed when hot magma or solids and gasses erupt onto Earth's surface through a vent
What is a volcano?
cooling magma and cooling lava are two ways this forms
What are minerals?
When sediments go through compaction and cementation
What is sedimentary rock?
The energy released in an earthquake travels in this form
What are seismic waves?
The circular hole at the top of a volcano
What is a crater?
This is a measure of how clear a gem is
What is clarity?
When sedimentary rock goes through heat and pressure
What is metamorphic rock?
This measures the amount of energy released by and earthquake, and this is the record of the date that details the magnitude of the waves.
What is a seismograph and what is a seismogram?
The most dangerous Pyroclast
What are Volcanic Blocks?
This is a measure of how a mineral reflects light, or how shiny it is
What is luster?
Igneous rock and metamorphic rock melted down
What is Magma?
