Tectonic Plates
What are other things that led scientists to believe that Pangea once existed?
Fossils from the same animals were found on both eastern south america and western africa. The geology and rocks were also similar.
Which of the two types of seismic waves are more destructive?
Surface waves are more destructive since they tend to last longer, have a lower frequency, and a larger amplitude.
How many volcanoes are located within the Ring of Fire?
75% of the Earth's volcanoes, or 450 volcanoes
Name the parts of the earth (in order)
The crust, the mantle, the outer core, the inner core
Why do scientists believe the Earth has a liquid outer core?
Scientists believe Earth has a liquid outer core because S-waves can’t reach regions around the globe that P-waves can.
What scale is used to measure damage caused by an earthquake?
Mercalli Intensity Scale
Name the differences between tectonic plates and plate tectonics.
Tectonic plates refer to the literal plates whereas plate tectonics refers to the movement of the plates.
P-waves are longitudinal waves and move faster than S-waves. They can move through solid and liquid material. S-waves, which are transverse waves and can only move through solid material.
Name three of the tectonic plates in between where the Ring of Fire is located
Located between several tectonic plates, including the Pacific, Juan de Fuca, Cocos, Indian-Australian, Nazca, North American, and Philippine Plates
