QuestionAnswer
Which of the following is a push - pull motion? Pwave
The most common cause of earthquakes is... Faults
Which of the following is a name of a volcano that has recently erupted? Active
Which of the following is made up of particles about the size of golf balls? Cinder
Which of the following is made up of particles about the size of grains of rice? Volcanic Ash
Quiet flows of runny lava produce... Shield Volcanoes
The smallest particle to come out of a volcano is... Volcanic Dust
A volcano that is known to have erupted but not in recent history, is called... a dormant volcano
Cinder cones result from... cinders piling up
The San Andres fault is located in... California
P waves from an earthquake... are push and pull waves, they are the fastest seismic wave, and they travel through solids, liquids, and gases
S waves... travel only through solids and move side to side
During earthquakes, the most violent shaking occurs... at the epicenter
A tsunami is caused by... underwater earthquakes
S waves differ from P waves in which S waves... travel through solids and move side to side
Using the Richter scale, which of these earthquake magnitudes is the strongest? 3, 5, 2, 8
The amount of damage caused by an earthquake does not depend on the distance of the seismograph from the epicenter
L waves... travel on the surface and are the slowest of all seismic waves
A volcano whose last eruption hasn't happened in recorded history is called... exinct
A _____ volcano is made by cinders piling up after explosive eruptions. cinder cone
The strength of an earthquake is measured according to a scale called the _____. Richter scale
A great sea wave is called a(n) _____. tsunami
The point on earth's surface directly above an earthquake's point of origin is called the _____. epicenter
An instrument that detects and measures seismic waves is called a(n) _____. seismograph
There are _____ main types of seismic waves associated with earthquakes. three
The fastest of the main seismic waves are the _____ waves. P
The opening or _____ in the earth's crust is the location where hot, liquid rock spills out onto the surface of the earth. vent
Volcanoes may develop a _____ or pit at the top. crater
In _____ volcano formation, eruptions are usually quiet and lava flows are runny, forming gentle slopes around the sides of the volcano. shield
Most of the damage to cities and towns during an earthquake comes from _____ waves. L
True or False The underground point of origin of an earthquake is called the epicenter. False
True or False L waves are surface waves. True
True or False Secondary waves cannot travel through liquids. True
True or False Earthquakes result from folding, which is a break in earth's crust. False
True or False Shields are volcanic bombs the size of golf balls that are hurled from a volcano during an eruption. False
True or False Dormant volcanoes have never erupted. False
True or False Extinct volcanoes will never, ever erupt. False
True or False The fire and ice zone is an earthquake and volcano zone in the Pacific Ocean region that includes the San Andres Fault. False
True or False Magma is molten rock that has reached the surface of the earth. False
Name an activity we did this chapter and tell what I was trying to help you learn by doing this activity. An activity we did this chapter was the epicenter lab in which we located epicenters with a "compass". By doing this lab you were trying to help us learn how to find an epicenter.
Contrast 3 types of particles that may erupt from a volcano. The types of volcanic particles are volcanic dust, volcanic ash, cinder, and volcanic bombs. They are all different because of their sizes; dust is the smallest, then ash (rice size), next cinder (golf ball sized), and bombs which are the biggest.
Contrast a shield volcano and a composite volcano. Shield and Compostite volcanoes are different in which shield volcanoes are formed by quiet lava flows and has a gradual slope, whereas composite volcanoes are formed by both cinder and lava .
Contrast P and S waves in an earthquake. P waves are different from S waves because P waves are faster than S waves, they move in push pull motions whereas S waves move in a side to side motion, and finally P waves travel through three types of matter whereas S waves only travel through solids
Compare and contrast lava and magma. Lava and magma are similar because they are the same thing (molten rock), the only difference is that Lava is above-ground and magma is underground.
