Earth is composed of layers of material with different properties. Which of the following is most likely to contain material that is in constant motion?
core
mantle
oceanic crust
continental crust
The chart below contains information on landforms.
Which can be inferred from the information in the chart about boundaries?
Trenches form at divergent boundaries.
Underwater ridges form at transform boundaries.
Faults form only at convergent boundaries.
Mountain ranges form at convergent boundaries.
The Mariana islands are volcanic islands that form an arc. The island arc is located in the North Pacific Ocean. These islands were formed by converging tectonic plates.
Which process had to occur in order for these islands to be formed?
melting of oceanic crust at mid-ocean ridge
melting of oceanic crust at subduction zones
production and deposition of magma from hot spots
production and deposition of magma from rift valleys
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?
floods
earthquakes
island building
seafloor spreading
Which geologic feature most likely forms when an oceanic tectonic plate is slowly subducted beneath a continental tectonic plate?
oceanic trench
mid-ocean ridge
continental hot spot
continental rift valley
A graph used for determining epicenter distance is shown below.
Suppose a seismograph at an earthquake monitoring station recorded the S wave from an earthquake 4.5 minutes after it received the earthquake’s P wave. Based on the graph, approximately how far is the earthquake’s epicenter from the monitoring station?
1200 km
2300 km
2800 km
3400 km
A scientist was examining a large boulder that was covered with lichens (a combination of fungi and algae). He chipped a piece of the rock and placed it under a microscope. He observed that the surface of the rock was breaking down underneath the lichen. Which was the scientist most likely observing?
the interaction between abiotic factors
the effects of chemical weathering
the process of deposition
the effects of abrasion
There are many natural rock formations such as the one shown.
Which two processes most likely removed the center portion of the rock and transported it to another location?
earthquakes and wind
tectonic activity and magma
chemical weathering and glaciers
mechanical weathering and water
Volcanoes release several gases during eruptions. Which of these gases has been shown to cause significant cooling of the climate for one or more years after an eruption?
water vapor
sulfur dioxide
carbon dioxide
hydrogen fluoride
A team of geologists are studying Earth's layers to understand how the differences in density and temperature influence geological processes. They develop a model to illustrate how these differences drive mantle convection and tectonic plate movements.
Based on the geologists' model, which of the following best explains the primary source of heat that drives mantle convection?
The heat that drives mantle convection comes from the sun and is absorbed by Earth's surface.
The primary source of heat for mantle convection is the radioactive decay of unstable isotopes in the crust and mantle, which causes density-driven motions.
Friction from tectonic plate collisions, due to varying densities, generates heat that drives mantle convection.
Heat from the inner core spreads outward through the mantle, driving mantle convection and tectonic plate movements.
Gloria is studying earthquakes and volcanoes and where they occur the dark lines in the map show tectonic plate boundaries.
The numbers indicate locations where people could live if Gloria wanted to live where there were few earthquakes and volcanoes. Which location should she choose?
1

The seismograph below records the arrival times of seismic waves at a station in Portland.
Using the seismograph data provided, which of the following correctly identify the arrival times for the P and S waves?
The P wave arrives at 120 seconds and the S wave arrives at 240 seconds.
The P wave arrives at 0 seconds, and the S waves arrives at 60 seconds
The P wave arrives at 0 seconds, and the S wave arrives at 120 seconds.
The P wave arrives at 60 seconds, and the S wave arrives at 180 seconds.
Students are analyzing a map of tectonic plates to predict the locations of volcanoes.
Based on their analysis, where are most volcanoes located?
Along convergent plate boundaries, where tectonic plates collide.
In the middle of tectonic plates, away from any boundaries.
At transform plate boundaries, where tectonic plates slide past each other.
Randomly distributed across Earth's surface without relation to plate boundaries.
