Which type of rock is formed when limestone is subjected to heat and pressure?
marble
100
What is the main source of heat in the magma that builds these mountain chains?
heat within the crust and mantle of Earth
100
Which geological event would MOST likely occur along the type of boundary demonstrated?
occurrence of earthquakes
100
Radioactive isotopes inside Earth are constantly decaying. This process results in
the generation of heat energy inside Earth.
100
Most volcanoes develop due to interactions between two tectonic plates. Which of the tectonic plate interactions is LEAST likely to produce volcanic activity?
two converging continental plates
200
Assuming the layers have NOT been disturbed, which layer would contain the MOST crystallized minerals?
Z
200
Which U.S. feature was formed through the geological process of continental accretion?
the Aleutian Islands of Alaska
200
Which type of plate boundary is MOST responsible for the formation of the Himalayan Range?
convergent boundary between two continental crusts
200
In certain areas, tectonic plates move over hot spots. Which landforms are MOST likely associated with these hot spots?
volcanoes
200
This volcano was MOST likely caused by which activity?
subduction at a convergent boundary
300
Near which geologic structure are the youngest rocks on Earth found?
active volcano
300
A volcano found in the center of a tectonic plate tends to be a result of which phenomenon?
activity at a hot spot
300
Certain activities occur at different plate boundaries due to movement at the boundary. Which activity would be the MAIN result of two tectonic plates slipping past one another?
earthquakes
300
Which will most likely occur before a volcanic eruption?
an increase in earthquake activity
300
In examining an area, a geologist discovered a thrust fault. He sketched the fault shown. Which MOST likely caused this geologic feature?
compressional forces
400
When an igneous intrusion comes into contact with surrounding rock, the surrounding rock will
recrystallize.
400
Which number is MOST likely the location of a volcano formed by a divergent boundary?
2

The structures created at convergent boundaries under the ocean are different than the structures created at those boundaries on land. Which statement describes this difference?
Under the ocean a trench will form, and on a continent mountains will form.
400
Scientists have measured the rate of growth of the Atlantic Ocean basin to be about 2 to 3 cm per year. This type of activity coincides with the formation of ridges on the ocean floor. What is the MOST likely cause of this activity?
movement of tectonic plates
400
Which term provides the MOST accurate classification of the geologic structure shown?
reverse fault
500
In areas where limestone is present underground, continued rains can lead to the formation of caves and sinkholes. Which processes are directly responsible for changing the limestone?
weathering and erosion
500
Based on the map, which city or town is located in an area of greatest earthquake hazard?
Charleston, SC
500
A geologist drew a diagram illustrating a section of a boundary between two tectonic plates. His diagram includes the geologic feature shown below.
divergent boundary between two continental plates
500
Certain movements of oceanic plates cause the formation of new crust on the ocean floor. Which plate movement would result in the formation of new crust?
two oceanic plates pulling away from each other
500
Scientists measure the increasing height of the Himalaya Mountains. Which of the following provides the BEST reason for the height increases of these mountains?
a convergent boundary between the Eurasian Plate and Indo-Australian Plate
