SOSE Assignment due tomorrow!!! The Grand Canyon Sequence. Students learn about river processes in these two activities: In Part 2 you will use the principles of relative dating to determine sequences of geological events as indicated by the layers and structures in the rocks.
Note that the azimuths cited here assume no rotation of the Pacific Plate during the last 75 Ma. Between which two rock layers use the names of the rock layers shown on the diagram does the unconformity occur? Enough data were gathered to allow the magnetic isochrons to be mapped out as color contours. Part 1 is on absolute age determinations using radioactive isotopes and their daughter products in geological materials.
GSA supports On the Cutting Edge
By performing and completing this lab, you will progress toward the following learning objectives for this course:. Finding Lab Activities Online As many us work on developing online courses we have to ask ourselves how to implement lab activities. The theory of sea floor spreading is part of plate tectonics theory.
Do all atmospheric gases contribute to the greenhouse effect? What is one major way coal is used today? Refer to the geologic time scale on page 219 for the names of each of the geologic time periods, as well as the absolute dates attached to each Period. To fully analyze the Juan de Fuca magnetic isochron map you also need to determine the age of selected magnetic reversals.
These data were gathered by a magnetometer towed behind a ship. Exploring Geology, 2nd Edition. The vertical lines are placed at 2 second intervals. Mineral identification and properties using photographs by Richard Harwood of Black Hawk College — students can identify minerals photographs based on mineral property choices. The white stripes between the colored stripes are areas where the ocean floor has reversed magnetism, with north and south switched around.
Determine relative geologic age sequences using the basic principles of relative age determination. Lab - Plate Tectonics. This sudden motion causes shock waves seismic waves to radiate from their point of origin called the focus and travel through the earth. Magnetic isochrons around the Juan de Fuca Ridge Click on the thumbnail above for a larger version of the image that opens in a new window. Details and get access to Porosity Check out Porosity. Students record channel width for water flow on a sand-filled stream table for different flow rates and slope angles.
Who is to say that the volcanic rocks dredged up from the underwater seamount Jingu for example are representative of all of Jingu's eruptive history? Four major unconformities are evident in the Grand Canyon cross-section. You can either print out and mail a copy of your marked-up exercise Part A from Dr. Refer to the geologic time scale on page 219 for the names of each of the geologic time periods, as well as the absolute dates attached to each Period.
Please make sure when using these activities to acknowledge the authors of the page. Methods To complete this lab, you will conduct the following types of observations, measurements or calculations, following the Calculations and Graphs standards Read, draw, and interpret maps of the earth. By performing and completing this lab, you will progress toward the following learning objectives for this course:.
In addition, there is a virtual mapping project. The direction of plate motion is given by the orientation of the chain of seamounts and volcanoes. Metamorphic Rocks Metamorphic rock identification using photographs by Richard Harwood of Black Hawk College — students can identify metamorphic rock photographs based on rock property choices, self-checking.

For further discussion of uncertainties, see original sources. A rate of motion, also known as speed, is ound by dividing the distance something has moved by the length of time it took to move that far. The Hawaii-Emperor chain of seamounts volcanoes resting on the ocean floor begins at the active, present-day location of the hot spot at the southeast side of the Big Island of Hawaii. General Exploring Earth Investigations by McDougal Littell Publishing - numerous online activities that use animations, interactive graphics, and imagery to help students gather information gleaned from lecture content Geology Lab Videos by Tom Braziunas at North Seattle Community College - students can view short video demonstrations of some of the physical geology lab activities Reynolds, et al.
Volcanoes Stromboli online - Volcanoes of the World by Jürg Alean, Roberto Carniel and Marco Fulle — this website can be used for virtual fieldtrips as well as a resource. Groundwater How does groundwater move through the ground? The faults show up on the map as straight, solid back lines offsetting the colored magnetic strips. The theory of seafloor spreading predicts that the magnetic profiles on either side of a spreading ridge should be mirror images, symmetric and equally spaced. The instrument recording the seismic waves is called a seismograph and the recording is a seismogram. The positive parts peaks of the magnetic profiles are where the rocks are magnetized pointing to magnetic north in the same direction as magnetic north is today.
Visualize the sizes and distances between different heavenly bodies, and turn off gravity to see what would happen without it! Paleontology Online rock and fossil identification kit by University of Tennessee — provides photographs and descriptions of various rocks and fossils. When completing the worksheet you will interpret a map of magnetic patterns on the ocean floor. Schist forms deep in the crust and must be uplifted and eroded to have the sediments that form limestone deposited on top. Examine, construct, and interpret diagrams, flow charts, and tables of information.
Answers to online dating questions
Each peak or valley on the magnetic profiles marks a magnetic isochron. Sean Fox, Carleton College Reuse: Earthquakes occur because of a sudden release of stored energy. Your membership is helping to ensure that this site can continue to serve geoscience educators. Students record channel width for water flow on a sand-filled stream table for different flow rates and slope angles. Other aspects of water erosion may be considered as well.
