Which type of stress causes deformation that leads to earthquakes at convergent plate boundaries?
tension
rebound
shear stress
compression
On December 26, 2004, a major tsunami occurred in the Indian Ocean. The tsunami traveled from its point of origin to as far away as Africa—nearly 5,000 km. The map below shows the origin of the tsunami and the direction the waves traveled. What was the cause of this tsunami?
an earthquake beneath the ocean
the impact of a large meteorite in the ocean
a sudden violent windstorm above the ocean water
a typoon moving from the Indian Ocean toward India
What causes an earthquake to happen?
rocks deform slowly as a result of stress
rocks along a fault move suddenly and release energy
large amounts of rock suddenly shift downward when large holes form underground
energy is transferred to rock layers from convection currents in the oceans and the atmosphere
During the year 2003, the number of earthquakes that occurred was higher than usual. The map below shows the locations of some of these earthquakes. Why do the dots on the map tend to form a long curving line along the western edge of the Pacific Ocean?
this part of the ocean has a high rate of hurricanes and typhoons
that part of the ocean is directly above the boundaries between tectonic plates
an increase in the number of tsunamis in the Pacific led to an increase in the number of earthquakes
there is pressure on the sea floor due to the weight of water of the Pacific ocean
The graph below shows how seismic waves travel through Earth. What can you infer about the material below 2900 km?
the material is iron
the material is rock
the material is solid
the material is liquid
The diagram below shows the layers of Earth’s interior. Which physical layers contain material from the mantle?
crust, lithosphere, asthenosphere
crust, asthenosphere, mesophere
mesosphere, inner core, outer core
lithosphere, asthenosphere, mesosphere
Which type of stress is most likely to occur at convergent plate boundaries?

The diagram below shows a type of mountain range that can form at divergent plate boundaries. What type of mountains are shown in the diagram?
island volcanic arc
folded mountains
fault-block mountains
continental volcanic arc
Look at the process shown in the illustrations below. What is the name of the hypothesis that is shown by this process?
continetal drift
magnetic reversals
rifting
subduction
What is the break in a body of rock along which one block slides relative to another called?
fault
focus
epicenter
earthquake
Why do folded mountain belts sometimes form at convergent plate boundaries?
Why do folded mountain belts sometimes form at convergent plate boundaries?
Because convergent plate boundaries occur above hot spots.
Because the rock is stretched apart and breaks, which allows magma to rise to Earth’s surface.
Because subducted oceanic lithosphere melts and rises as magma to Earth’s surface.
A geologist is studying an area after an earthquake. She notices that two streams have changed course. What would most likely explain the movement of the streams?
The stream runs across a fault in a rift zone where two plates are diverging.
The stream runs across a hot spot far from any tectonic plates.
The stream runs across a transform fault that was offset (moved to a different location) by the earthquake.
The stream runs across a subduction zone where two plates are converging.
On which type of plate would you find thinner, denser rock made mostly of basalt?
oceanic plate
continental plate
asthenospheric plate
rocks on all plates have the same thickness and density
What type of stress is most likely to occur at divergent plate boundaries?
faulting
tension
shear
compression
Which of the following statements provided early evidence supporting Alfred Wegner's hypothesis of continental drift?
interlocking shapes of present-day coastlines
mid-ocean ridges generating new sea floor
matching magnetic patterns on the sea floor
dating of rocks showing increase in age as distance from mid-ocean ridge increases
Imagine that you collected the data below to study the age and location of rocks on the sea floor. Based on the chart, if a rock is located 50km from the mid ocean ridge, how old is it likely to be?
500,000 years old
1,000,000 years old
2,000,000 years old
4,450,000 years old
Which of the following statements summarizes how the formation of the solar system was similar to the differentiation of the Earth's Layers?

In both processes, the densest materials were evenly distributed
