U3 - Topic 4 Plate Tectonics

The primary cause of convection currents in the Earth's mantle is believed to be

• differences in densities of Earth materials

• subsidence of the crust

• occurrence of eaarthquakes

• rotation of the Earth

Contact zones between tectonic plates may produce trenches. According to the Earth Science Reference Tables, one of these trenches is located at the boundary between which plates?

• Austrlian and Pacific

• South American and African

• Australian and Antarctic

• North American and Eurasian

Base your answer to the questions on the map below and your knowledge of Earth Science. The map shows crustal plate boundaries located along the pacific coastline of the United States. The arrows show the general directions in which some of the plates appear to be moving slowly. Which feature is located at 20 degrees North latitude and 109 degrees West longitude?

• San Andreas fault

• East Pacific rise

• Baja, California

• Juan de Fuca Ridge

Base your answer to the questions on the map below and your knowledge of Earth Science. The map shows crustal plate boundaries located along the pacific coastline of the United States. The arrows show the general directions in which some of the plates appear to be moving slowly. Geologic studies of the San Andreas fault indicate that

• many earthquakes occur along the San Andreas fault

• the North American plate and the Pacific plate are locked in dynamic equilibrium

• the subduction zone is the boundary at which the crustal plates are drifting apart

• the age of the bedrock increases as distance from the fault increases

Base your answer to the questions on the map below and your knowledge of Earth Science. The map shows crustal plate boundaries located along the pacific coastline of the United States. The arrows show the general directions in which some of the plates appear to be moving slowly. Which features are most often found at crustal plate boundaries like those shown on the map?

• meandering rivers and warm-water lakes

• plains and plateaus

• geysers and glaciers

• faulted bedrock and volcanoes

Base your answer to the questions on the map below and your knowledge of Earth Science. The map shows crustal plate boundaries located along the pacific coastline of the United States. The arrows show the general directions in which some of the plates appear to be moving slowly. What would a study of the EAst Pacific rise (a mid-ocean ridge) indicate about the age of the basaltic bedrock in this area?

• The bedrock is youngest at the ridge

• The bedrock is oldest at the ridge

• The bedrock at the ridge is the same age as the bedrock next to the continent.

• The bedrock at the ridge is the same age as the bedrock at the San Andreas fault.

Base your answer to the questions on the map below and your knowledge of Earth Science. The map shows crustal plate boundaries located along the pacific coastline of the United States. The arrows show the general directions in which some of the plates appear to be moving slowly. The best way to find the direction of crustal movement along the San Andreas fault is to

• study of earth's present magnetic field

• observe erosion along the continental coastline

• measure gravitational strength on opposte sides of the fault

• match displaced rock types from opposite sides of the fault

Base your answer on your knowledge of Earth science, the Reference Tables and the diagrams which represent geologic cross sections of the upper mantle and crust at four different Earth locations. In each diagram the movement of the crustal sections (plates) is indicated by arrows and the locations of frequent earthquakes are indicated by symbols as shown in the key. [Diagrams are not drawn to scale.] Which location best represents the boundary between the African plate and the South American plate?

• A

• B

• C

• D

Base your answer on the diagram. The diagram shows a portion of the Earth's oceanic crust in the vicinity of the mid-Atlantic ridge. The stripes in the diagram represent magnetic bands of igneous rock formed in the oceanic crust. The orientation of the Earth's magnetic field at the time of rock formation is shown as the arrows within each band. Letters A, B, C, D and E represent locations on the seafloor. According to the diagram, which two locations have rock with the same magnetic orientation?

• A and B

• A and E

• B and E

• D and E
