Plate Tectonics
Plates move away from each other at this boundary.
What is divergent?
The three types of faults.
The location where the rock ruptures.
What is the focus or hypocenter?
The height of a wave from the center line to the crest.
What is amplitude?
Seafloor spreading is driven by this.
What is convection?
Plates move towards each other at this boundary.
What is convergent?
Strike-slip faults are caused by this type of stress.
What is shear?
The area on the surface of the Earth directly above the point where the rock ruptures.
What is the epicenter?
Deadly ocean waves caused by an undersea earthquake.
What is a tsunami?
Apparent polar wander states that.
What is the poles' move over time?
Made up of both the crust and the upper mantle. This layer is easily cracked or broken.
What is the lithosphere?
If one were to stand in a fault, the wall that is above them (they could touch it with their hands) is known as.
What is a hanging wall?
The scientific tool that is used to determine where an earthquake occurs.
What is a seismograph?
Continental margins that are near plate boundaries.
What are active margins?
The energy from an earthquake is transmitted by these waves.
What are seismic waves?
The Scientist who proposed the idea of seafloor spreading.
Who is Harry Hess?
Normal faults are caused by this type of stress.
What is tension?
The fastest type of body wave that can travel through solids, liquids, and gases.
What are P-waves (primary)?
A long chain of mountains that rise high above the seafloor. Seafloor spreading happens here.
What are mid-ocean ridges?
The San Andreas Fault is an example of this fault.
What is strike-slip?
The layer of the Earth that is composed of the mantle and acts like silly putty. This layer can bend.
What is the asthenosphere?
The hanging wall moves up relative to the footwall.
What is a reverse fault?
A slow wave type that produces a side-to-side motion.
What are love waves?
A line of volcanoes formed on oceanic plates.
What is an island arc?
There is oceanic and continental crust. The type of crust that is denser is.
What is Oceanic Crust?
