Describing Earthquakes
100
Where do most earthquakes and volcanoes occur.
What is PLATE BOUNDARIES
100
Molten rock that erupts onto Earth's surface.
What is LAVA
100
A vent in Earth's crust through which melted- or molten- rock flows.
What is VOLCANO
100
Vibrations in the ground that result from movement along breaks in Earth's lithosphere.
What is EARTHQUAKE
100
Wave that causes particles in the ground to move in a push-pull motion similar to a coiled spring. They can be recorded first in an earthquake.
What is P WAVE
200
The scale that we use to determine the magnitude of an earthquake.
What is RICHTER MAGNITUDE SCALE
200
Molten rock below Earth's surface.
What is MAGMA
200
Volcanoes that are not associated with plate boundaries.
What is HOT SPOT
200
Energy that travels as vibration on and in Earth.
What is SEISMIC WAVE
200
Wave that causes particles to move up and down at right angles relative to the direction the wave travels.
What is S WAVE
300
The scale we use to describe an earthquake's intensity.
What is MODIFIED MERCALLI SCALE
300
Volcano common along divergent plate boundaries and oceanic hot spots. Large with gentle slopes of basaltic lavas.
What is SHIELD VOLCANO
300
Tiny particles of pulverized volcanic rock and glass.
What is VOLCANIC ASH
300
Scientist that study earthquakes.
What is SEISMOLOGIST
300
Wave that causes particles in the ground to move up and down in a rolling motion.
What is SURFACE WAVE
400
A break in Earth's lithosphere where one block of rock moves toward, away from, or past another.
What is FAULT
400
Small, steep-sided volcanoes that erupt gas-rich, basaltic lavas.
What is CINDER CONE
400
A liquid's resistance to flow.
What is VISCOSITY
400
A graphical illustration of seismic waves.
What is SEISMOGRAM
400
The location on Earth's surface directly above where the earthquake originates.
What is EPICENTER
500
An area of earthquake and volcanic activity that surrounds the Pacific Ocean.
What is RING OF FIRE
500
Large, steep-sided volcanoes that result from explosive eruptions of andesite and rhyolitic lava and ash along convergent plate boundaries.
What is COMPOSITE VOLCANO
500
What type of viscosity do the volcanoes on Hawaii have?
What is HIGH VISCOSITY
500
Measures and records ground motion and can be used to determine the distance seismic waves travel.
What is SEISMOMETER
500
Where the earthquake originates.
What is FOCUS
