Which of the following major earthquakes did not occur at a boundary between tectonic plates?
South Carolina (U.S.A.) 1886
Messina (southern Italy) 1908
Chillan (Chile) 1939
San Francisco (U.S.A.) 1906
What is the fewest number of seismographic stations that must record the arrival time of P and S waves in order for the epicenter of an earthquake to be located? 1 0 3

Which geologic event occurred first? Iceland formed at the mid-Atlantic ridge.
Pangaea underwent formation. India collided with Asia, forming the Himalayan Mountains. South America and Africa split apart.
Even though the Earth's inner core is hotter than the liquid outer core, it is still solid because - there is more water in the outer core and it dilutes the materials the pressure from all of Earth's layers keeps it in a solid state the heat rising from the inner core is melting the outer core the outer core is farther from the center, and there is less gravity holding it together
All of the following features of the ocean indicate tectonic activity except - seamounts abyssal plains mid-ocean ridges
trenches
The point from which an earthquake originates is called the -
epicenter
focus
shock wave
fault line
Which of the landforms is most likely to result when two continents collide? What does Pangaea mean? It is the name of an ancient supercontinent.
It is the name of an extinct volcano.
It is the French word for volcano. It is a huge disruption of the Earth's atmospheric circulation.
What is usually responsible for an earthquake? Force changes from the moon pulling on Earth Slippage along faults within Earth's crust
Pressure buildup within the mantle
Weathering along coastlines
Scientists use volcanoes and earthquake activity to establish - lines of latitude plate boundaries the density of rock layers borders between countries
Each dot on the above diagram marks the origin of an earthquake. The area with the highest concentration of earthquake origins marks - the location of a developing igneous intrusion a line of Earth's magnetic field a seam of soft rock, such as limestone the path of the subducting tectonic plate
Seismic waves generated by an earthquake at point R are recorded at locations W and X. Which pair of seismographs is more accurate? The Earth's mantle is made up of very hot material that rises to the top of the mantle, cools, then sinks, reheats, and rises again, constantly repeating the cycle. This action, which causes the Earth's crust to move, is known as - hot spots advection forces convection currents magnetic fields
The sketch above shows a seismogram, which is a record of the primary waves and secondary waves emitted by an earthquake. Primary waves and secondary waves are generated at the same time, but primary waves are recorded first because they - travel faster do not travel through water are smaller travel a shorter route
The edges of moving crustal plates are often defined by - intercontinental plains ocean basins frequent seismic activity Earth's largest rivers
One part of California is on the Pacific Plate, while the remainder of the state is on the North American Plate. The two plates are moving to the northwest at different speeds, causing one plate to slide past the other. This movement in plates creates a - strike-slip fault normal fault thrust fault reverse fault
Which of the following is not considered a result of the movement of tectonic plates? Earthquakes
Karst topography
Mountain ranges Increased volcanic activity
The diagram shown illustrates which geological process? Folding
Faulting Metamorphis m Weathering
As landmasses drifted over the Earth from 180 million years ago to the present day, one significant change that occurred was the - increase in overall landmass size decrease in the number of mid-ocean ridges increase in the number of trenches decrease in the number of transverse faults
All of the following supports the theory of continental drift except that - there are similar fossils on different continents the continents seem to fit together like pieces of a puzzle mountain ranges in South America and Africa line up the North Pole and Antarctica are covered with ice
When the sea floor spreads apart, volcanoes and ridges are formed because - sediments are deposited where the floor spreads, building ridges as the plates pull apart, magma moves to the surface, building ridges ocean water pushes down on the surrounding sea floor, pushing up ridges underwater earthquakes lift the sea floor into long ridges The formations at X and Y in the picture above were created by - tension rifting shearing compressio n
The mountain shown is composed of deformed sedimentary layers. They are located near a tectonic plate boundary and are still increasing in elevation due to - transform faulting of a tectonic plate seafloor spreading of tectonic plates colliding tectonic plates subduction of a tectonic plate
How should the earthquake damage in the picture be ranked according to the modified Mercalli Intensity Scale? V VI I IX

An earthquake struck San Diego, California. The above map and table show that the approximate difference in arrival times between the P-wave and S-wave at Seattle is - 2 minutes 3 minutes 4 minutes 5 minutes
The diagram above is similar to one drawn by Antonio Snider-Pelligrini in 1858. What data was he trying to explain with this diagram? The distance between the Eastern and Western Hemispheres The reason for similar fossils in Africa and South America
The presence of earthquakes on different continents
The variations in depths of the Atlantic Ocean Which provides the best evidence for the theory that faults and volcanoes are results of tectonic plate interactions? Faults on tectonic plates are in constant motion, but volcanoes may not erupt for many years. Faults and volcanoes existed long before there were tectonic plates. Tectonic plates that have many faults do not usually have volcanoes. Faults and volcanoes are often found at tectonic plate boundaries.
The folding and faulting found in the rocks of the Blue Ridge Mountains of Virginia were created by - collisions of continental plates wave action of prehistoric ocean the Coriolis effect heating and cooling of the prehistoric atmosphere
Identical rock types, identical fossils, and very similar mountain ranges are found on different continents that are separated by a wide ocean. Which of these best explains these observations? Organisms traveled between these continents on land bridges. The same forces erode mountains in different locations. These continents were joined together at one time in the past. Some rock types are very common and are found everywhere.
The Marianas Trench in the Pacific Ocean is 36,160 feet below sea level. This deep oceanic trench is caused by - swift ocean currents eroding away the ocean floor the collapse of an empty magma chamber in a large volcano excessive boat traffic disrupting the normal sedimentation process two tectonic plates colliding and one plunging below the other
