Earth's Layers, Plate Boundaries Flashcards
In what type of fault does the hanging wall slip down relative to the footwall?
Normal Fault
In what type of fault does the hanging wall slide up and over the footwall
Reverse Fault
In what type of fault do rocks on either side of the fault slip past each other?
Strike Strip
A major volcanic belt that circles the Pacific Ocean
Ring of Fire
The study of earthquakes (seismic waves)
Indirect Evidence
The study of rock samples
Direct Evidence
An area where lava frequently erupts at the surface, independent of plate boundary processes. The Hawaiian Islands formed over this.
Hot spot
The point beneath Earth’s surface where rock breaks under stress to trigger an earthquake
Focus
Solid dense ball of metal made of iron and nicket
Inner Core
The Earth’s magnetic field results in movement here. Made of hot molten metal
Outer Core
Convection Currents flow here
Asthenosphere
Geologists think that movement in Earth’s Plates are caused by the convection currents in the…
Asthenosphere
Part of the upper mantle and crust
Lithosphere
Is broken into separate sections called plates
Lithosphere
Deepest Layer of the Earth’s Layers
