GEOL 105: Pre-lab Quiz 2: Plate Tectonics

In Google Earth Pro, under Places, under Lab2_PlateTectonics.kmz, double click on "San Andreas". Find the San Andreas Fault, the boundary between the Pacific Plate on the west and the North American Plate on the east. What direction is the Pacific Plate moving along the San Andreas Fault?

Northwest

What type of plate tectonic boundary occurs where the Nazca plate meets the South American plate?

convergent-subduction

The picture below shows a section of the Newark West Quadrangle topographic map produced by the USGS. What is the contour interval of this topographic map (given in feet)?

10

In Google Earth Pro, under Places, under Lab2_PlateTectonics.kmz, double-click on the Mariana Convergent Margin in the Places panel to view a classic subduction zone setting. The Pacific plate lies to the right and the Philippine plate lies to the left. An island arc (often actively volcanic) is typically found near active subduction zones. About how far in kilometers is the island arc (i.e., the island of Saipan) from the Mariana Trench?

181 km

The picture below shows a section of the Newark West Quadrangle topographic map produced by the USGS. What is the elevation of Iron Hill at its highest point (note that elevations are given in feet)?

340 feet

Using Google Earth Pro, determine the latitude of the UD logo on the 50-yard line of Delaware Stadium.

39°39'42" N

In Google Earth Pro, under Places, under Lab2_PlateTectonics.kmz, double-click on the Rio Grand Rift placemark to fly there. At the Rio Grand Rift placemark you can make out a fairly large tectonic rift feature, located to the southwest of the placemark. Use the measure tool to measure across the Rio Grand Rift. Measure from side to side across the rift from Los Alamos to the mountain peak Cerro Pinon. Approximately how wide is the rift here in kilometers?

About 37 km

In Google Earth Pro, under Places, under Lab2_PlateTectonics.kmz, double-click on the Rio Grand Rift placemark to fly there. At the Rio Grand Rift placemark you can make out a fairly large tectonic rift feature, located to the southwest of the placemark. The Rio Grand Rift extends south from this placemark to El Paso. Within the Measure tool menu, choose "Path" and trace a Path along the rift zone (the Rio Grand River). Path enables you to trace a line that is not straight by single-clicking when your feature of interest turns. How long is the "Path" of the Rio Grand Rift in kilometers?

About 530-560 km

Transform boundaries are associated with tensional stress.

False

In Google Earth Pro, under Places, under Lab2_PlateTectonics.kmz, double-click on the Mariana Convergent Margin in the Places panel to view a classic subduction zone setting. The Pacific plate lies to the right and the Philippine plate lies to the left. Which plate do you think is being subducted, the Pacific Plate or the Philippine plate?

Pacific Plate

In Google Earth Pro, under Places, under Lab2_PlateTectonics.kmz, double-click on the Rio Grand Rift placemark to fly there. At the Rio Grand Rift placemark you can make out a fairly large tectonic rift feature, located to the southwest of the placemark. What kind of tectonic boundary causes a rift zone?

divergent

What type of plate tectonic boundary occurs where the South American plate meets the African plate?

divergent

At ___________ boundaries plates move away from each other, perpendicular to the boundary; at _________ boundaries they slide past each other, parallel to the boundary.

divergent; transform

The term ____ refers to solid material that deforms and flows under stress.

ductile

The picture below shows a section of the Newark West Quadrangle topographic map produced by the USGS. Match the symbol on the map below with the feature it represents.

red line - interstate highway black line - road green-shaded territory - park brown line - elevation contour dot - house

The two types of convergent plate boundaries are continent-continent collision zones and ___________.

subduction zones

In Google Earth Pro, under Places, under Lab2_PlateTectonics.kmz, double click on "San Andreas". Find the San Andreas Fault, the boundary between the Pacific Plate on the west and the North American Plate on the east. What type of plate boundary forms the San Andreas Fault?

transform
