Volcanoes
Lava and other volcanic materials are expelled through this.
What is a crater?
Point in Earth where these vibrations or movements first release stored energy.
What is Focus of an earthquake?
These cause earthquakes and volcanoes.
What is tectonic plates?
When part of rock breaks, a fracture or zone of fracture develops between two blocks of rock.
What is a fault?
This volcano is is less than 300m in height and forms around other volcanoes.
What is a Cinder Cone Volcano?
Vibrations move outward in this form
What is seismic waves?
There are 15 or so of these plates.
What is major or minor tectonic plates?
When rocks are pulled apart under tension force.
What is a normal fault?
Mountains with steep sides composed of alternating layers of lava and ash.
What is a Composite Volcano?
This scale measures magnitude of Earthquakes.
What is Richter scale?
The plate mostly made up of silicon and magnesium.
What is Oceanic Plates?
Compression force between two rocks cause rock above a fault to move up compared to the rock below the fault.
What is Reverse Fault?
This lava that erupts has low viscosity and flows freely across land to form flood basalts.
What is Fissure Eruptions?
Reason for rocks to break
What is accumulation of potential energy?
This plate is primarily made up of silicon and aluminum.
What is Continental Plates?
Cause rock to move past one another in opposite directions along Earths surface.
What is Strike-Slip Fault?
This is the largest type of volcano on Earth.
What is a shield volcano?
Continued strain on these rocks makes them sometimes break and sometimes the broken pieces snapback.
What is elastic rebound?
These currents cause the movement of tectonic plates.
What is convection currents?
