Earth Layers
The earth is composed primarily of this
What is rock?
Most of Earth's volcanoes are found here
What is tectonic plate boundaries?
Boundary where new material (crust) is created
What is divergent boundary?
The scientist who studies earthquakes
What is seismologist?
The resistance to flow
What is viscosity?
The outer layer of the earth
What is the crust?
Hot, molten rock that flows from a volcano
What is lava?
Boundary where plate material (crust) is destroyed
What is convergent boundary?
The type of seismic wave that is the fastest and moves by compressing and expanding like an accordion
What is P wave?
The plate that is thicker than the oceanic plate
What is the continental plate?
Earth's inner core is composed primarily of this
What is solid iron and nickel?
The Ring of Fire, a region with many active volcanoes, circles this ocean
What is Pacific?
The boundary that most of the world's greatest mountain ranges occur near
What is convergent boundary?
The waves generated by an earthquake that travel through a medium.
What is mechanical waves?
The layer of the earth that is a convective layer
What is the mantle?
The layer of the earth divided into plates.
What is the crust?
Volcanic activity is related to this.
What is tectonic plate movement?
When rock layers are stretched apart at divergent boundaries
What is tension?
The instrument that records vibrations in the ground and determines the location and strength of an earthquake.
What is seismograph?
The German scientist Alfred Wegener developed this hypothesis.
What is continental drift?
The solid outer layer of the Earth that consists of the crust and the rigid upper layer of the mantle
What is the lithosphere?
A place where volcanoes occur
What is hot spots, subduction zones, or divergent boundaries? (any of these are correct)
The process that best explains the driving force behind tectonic plate movement
What is sea-floor spreading?
The seismic wave that causes the most damage
What is surface wave?
The point beneath Earth's surface where rock breaks under stress and trigger an earthquake
What is the focus?
