Earthquakes can be severe along the San Andreas Fault in Southern California, but volcanoes are nonexistent. Which statement BEST explains this pattern?
The crust is thin and weak at the location of this fault
The material along this fault is smooth and fine grained.
The material in the mantle solidified due to cooling under this fault.
The crustal plates slide along each other without subducting at this fault
A volcano found in the center of a tectonic plate tends to be a result of which phenomenon?
strong earthquake
activity at hot spot
pressure in thick sediments that produces heat
unusually excessive erosion that wears away at bedrock
A volcano releases a towering plume of toxic ash and gases into the atmosphere. Which of these would best allow scientists to warn officials of a need for evacuation of people living far away from the volcano?
computer modeling of movement of the atmosphere
an accurate measurement of the height of the volcano
a careful count of the number of people living near the volcano
an estimate of the number of gas masks available for emergency personnel
A lahar is a mixture of water and rock fragments that can flow down a volcano after an eruption. Based on the characteristics of their adjacent volcanoes, which of these areas would have the lowest probability of experiencing a lahar after an eruption?
a farmstead in Iceland, near volcanoes and massive glaciers
a city in Colombia, next to a volcano with a snow-covered peak
a ranch in Hawaii, near a volcano that is rising up from the ocean floor
a town in Washington state, next to volcanic ranges and a large river valley
Where are most volcanoes located?
at divergent boundaries, transform boundaries, and hot spots

On the ocean floor, there are long mountain ranges called mid-ocean ridges. Which description explains how these geological structures were formed?
a transform boundary where one oceanic plate slides past another oceanic plate
a divergent boundary where two oceanic plates move apart from one another
