As the Pacific Plate moves over the Hawaiian hot spot, magma punches up through the Pacific Plate, creating an active volcano. View the above image, a cross-section side-view of a cut-out through the crust of the Grand Canyon. A seismic wave is simply a means of transferring energy from one spot to another within the earth. Your colleagues and students around the world will thank you! The theory of sea floor spreading is part of plate tectonics theory. Its hard to explain.
The radius of this circle i. Deformation How do rocks respond to stress? Images None found in this page Files None found in this page. Activities about age dating, river discharge and river flooding are available.
Answers to online dating questions
Activities about age dating, river discharge and river flooding are available. Think, behave, and communicate scientifically by showing results of measurements and calculations with units correctly included in the mathematics and results and numbers rounded appropriately at the end, by making graphs of measured plate motions that are properly depicted and labeled, and by answering essay questions about how plates move based on your results. Exploring Geology, 2nd Edition. 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.
Click More Information below. I can't find the answer anywhere! The negative values valleys of the magnetic profiles are where the rocks are magnetized pointing to magnetic north, in the opposite direction from where magnetic north is today. In the sequence of geological eons, eras, or periods, where is the unconformity located? How can we determine what direction a plate is moving and the speed at which it is moving?
To fully analyze the Juan de Fuca magnetic isochron map you also need to determine the age of selected magnetic reversals. See topographic maps above for links to landform maps. Furthermore, volcanoes do not have a single age; a typical Hawaiian volcano builds up over several hundred thousand years.
Mineral identification and properties using photographs by Richard Harwood of Black Hawk College — students can identify minerals photographs based on mineral property choices. Play a game that tests your ability to match the percentage of the dating element that remains to the age of the object. Carbon-14 decays to Nitrogen-14 with a half-life of 5,730 years. Listed below are some example lab activities that you might find useful as examples of others have used or even as lab activities to have your students do. The worksheet contains a different set of more detailed questions that you will answer and turn in.
For each of the four major unconformities in the Grand Canyon, answer each of the following questions: Images None found in this page Files None found in this page. It is very difficult to sample Jingu's older rocks; they are covered by the young lavas.

Answer Questions So, I know that there are alot of people who believe the earth is flat. To determine isochron ages on this map, you can use the colors of the isochrons and the vertical column showing the age of oceanic crust. This energy has built up over long periods of time as a result of tectonic forces within the earth. Use scientific tools to measure thickness, velocity and glacial budget. Because these are real-world data the magnetic isochrons do not form perfectly parallel stripes on either side of the ridge. Its hard to explain.
For a map scale, one cm centimeter equals approximately 66 km on a printout of the bigger copy. The actual records of earthquake waves are far more complicated than what is presented here. This may seem rather rather slow to us, but is very fast on the geological time scale. Move the sun, earth, moon and space station to see how it affects their gravitational forces and orbital paths. You are to locate the epicenter of an earthquake by making simple measurement on three seismograms that will be sent to you by the Virtual Earthquake program.
February 10, 2019 Short URL: Are you using free Virtual Lab materials you found on the web in your teaching or your learning? Strong seismic waves can cause great local damage and they can travel large distances. The magnetic isochrons are not in their original configuration. Hot spot tracks also give the speed of plate motion, if the length of the chains of volcanoes and seamounts, and the ages of the volcanoes and seamounts are known see data table below. Virtual museum of fossils by Valdosta State University.

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. The two chains meet at a prominent bend, around the underwater seamounts Daikakuji and Yuryaku. You are to locate the epicenter of an earthquake by making simple measurement on three seismograms that will be sent to you by the Virtual Earthquake program.
The speed of an earthquake wave is not constant but varies with many factors. Students can search for minerals by class or alphabetically. Hot spot tracks are very important geologic features for determining both the direction and speed of the plate upon which the seamounts rest.
