Volcanoes
These are usually created at a subduction zone when two tectonic plates collide.
What is a volcano?
Ground movement is caused by a release in pressure from plate tectonics.
What is an earthquake?
Normal, reverse, strike-slip, and oblique.
What are faults?
Caused by underwater earthquakes and underwater volcanic eruptions leading to large waves.
What is a Tsunami?
The crust, mantle, outer core, and inner core.
What are the four main layers of Earth?
A large ring of volcanoes.
What is The Ring of Fire?
The strength of earthquakes is measured by ________.
What is magnitude?
Faults are known to have many _________.
What is earthquakes.
What is avoiding a tsunami?
There are two types of this. The first is oceanic, and the second is continental.
What are the two types of crust?
Few volcanoes are found in this underwater ridge region that is located in the Atlantic Ocean.
What is the Mid-Atlantic Ridge?
A way to measure earthquakes from 0 to 9.
What is the Richter Scale?
A fault can be a __________ __________, but not all __________ __________can be faults.
What are plate boundaries?
Forests, ditches, slopes, or berms.
What are ways to slow water from a tsunami?
One of the four layers of Earth that makes up around 80% of the Earth's volume.
What is the mantle?
When continental crust subducts an oceanic plate, magma escapes from the mantle to the surface through vents and fissures.
What is one cause of volcanoes?
Another method of measuring earthquakes other than the Richter Scale.
What is the Mercalli Scale?
A few millimeters to thousands of kilometers.
What is the length of a fault?
Water can be turned to strategically placed angles, walls, and ditches.
What is steering tsunamis?
What is the lithosphere?
An area of magma hotter than surrounding magma causes thinning of crust and volcanic activity.
What is a hotspot?
A magnitude of 1 is __________ times greater than a magnitude of 4.
What is 1,000 times greater?
A well-known and first-named fault. This fault has a strike-slip movement where part of the block moves in the opposite direction of another block causing what looked like gaps in fences.
What is The San Andreas Fault?
Walls, hardened terraces, and parking structures.
What are ways of blocking tsunamis?
Beneath the lithosphere lies the second layer of the Mantle.
What is the asthenosphere?
