Daily Quadruple: Point on the surface directly above where the rock layers break and move, during an earthquake.
Epicenter
Molten material pouring out of the Earth's surface?
lava
Daily triple: Molten rock underground?
magma
What type of volcano forms when loose rock fragments and cinders are released from a gas-rich magma eruption resulting in small steep sided volcanoes with cylindrical bases?
cinder cone volcano
Daily double: Volcanoes with steep slopes of alternating ash and lava flows is called a:
strata cone volcano or composite cone
Daily Double:Which seismic wave is usually first
P-wave
Volcanoes lining the boundaries of the Pacific Ocean form what is called the?
Pacific Ring of Fire
Daily Double: The bending of rock layers is called?
folding
Caused by liquefaction during an earthquake. What is it called when sand shoots out of the ground into the air?
sand volcano
A process in which shaking of the ground causes soil to act as a liquid?
Liquefaction
What type of volcanic material thrown out by a volcano is the smallest?
ash
Daily Double:Which seismic wave is used to determine the strength of an earthquake?
S-wave
What type of stress causes a strike-slip fault?
shearing
Daily Double: What type of stress causes a reverse fault?
compression
What type of stress causes a normal fault?
tension
Rocks stressed beyond their elastic limit will snap(or break), this creates a sudden movement on the surrounding rocks. This sends out vibrations in all directions. These vibrations are called?
seismic waves
A earthquake with a Richter value of 2 releases how many times as much energy as an earthquake with a Richter value of 1?
32 times as much
Smaller earthquakes that follow a major earthquake are called?
aftershocks
what type of folding has the wave like lines going down?
syncline
If there are three seismograph readings and one of the is has the smallest squiggles is it farther or closer to the earthquake then the one with the biggest squiggles?
farther
what is the term for how seismologist locate an earthquake's epicenter?
Trianglulation
What fault is formed by the stress tension?
normal fault
What type of fault has the stress compression?
reverse fault
What type of fault has the stress shearing?
strike-slip fault
what type of fold has the wave like lines pointing upwards?
anticline
