Earthquake
The study of earthquakes.
What is seismology?
Waves that travel through the Earth’s interior.
What are body waves?
The type of crust found under oceans.
What is oceanic crust?
Heat transfer by direct contact.
What is conduction?
The idea that continents were once joined together.
What is Continental Drift Theory?
The instrument that records earthquake vibrations.
What is a seismograph?
The fastest seismic waves.
What are P-waves?
The rigid outer layer of the Earth.
What is the lithosphere?
Heat transfer by movement of material.
What is convection?
The supercontinent that once existed.
What is Pangaea?
The point inside the Earth where an earthquake begins.
What is the hypocenter?
Waves that cannot travel through liquids.
What are S-waves?
The soft, flowing layer beneath the lithosphere.
What is the asthenosphere?
Mass divided by volume.
What is density?
The theory that explains the movement of Earth’s plates.
What is plate tectonics?
The point on Earth’s surface directly above the hypocenter.
What is the epicenter?
Surface waves that move the ground in a rolling motion.
What are Rayleigh waves?
The boundary between the lithosphere and asthenosphere.
What is the Moho?
Heat transfer through electromagnetic waves.
What is radiation?
The process that creates new oceanic crust at mid-ocean ridges.
What is sea-floor spreading?
The method used to find an earthquake’s epicenter using three seismograph stations.
What is triangulation?
Surface waves that move the ground side to side and cause damage.
What are Love waves?
The boundary between the mesosphere and the outer core.
What is the Gutenberg Discontinuity?
Rising warm material and sinking cool material due to heat differences.
What are convection currents?
The process where old oceanic crust is recycled back into the mantle.
