Overlays are datasets with transparent backgrounds that contain foreground data used to augment other SOS datasets.This particular dataset overlays tectonic plate boundaries, with types of boundaries differentiated in color, onto any dataset that you are viewing.
Overlays can help provide context for your audience and make the datasets easier to understand, as well as provide information that may be useful to illustrate related global ideas.
Overlays are accessible on the SOS Remote app for iPad/iPhone/iPod Touch on version 4.0.2 and above.
Simply tap the Overlays button in the upper right hand corner of the Presentation tab to open the list of available overlays. Note that Overlays may also be pre-programmed into a playlist as a layer.
ESS2.B Plate Tectonics & Large Scale Interactions. Maps show where things are located. One can map the shapes and kinds of land and water in any area.
ESS2.B Plate Tectonics & Large Scale Interactions. Earth’s physical features occur in patterns, as do earthquakes and volcanoes. Maps can be used to locate features and determine patterns in those events.
ESS2.A Earth Materials and Systems. Energy flows and matter cycles within and among Earth’s systems, including the sun and Earth’s interior as primary energy sources. Plate tectonics is one result of these processes.
ESS2.B Plate Tectonics & Large Scale Interactions. Plate tectonics is the unifying theory that explains movements of rocks at Earth’s surface and geological history. Maps are used to display evidence of plate movement.
ESS2.A Earth Materials and Systems. Feedback effects exist within and among Earth’s systems.The geological record shows that changes to global and regional climate can be caused by interactions among changes in the sun’s energy output or Earth’s orbit, tectonic events, ocean circulation, volcanic activity, glaciers, vegetation, and human activities.
ESS2.B Plate Tectonics & Large Scale Interactions. Radioactive decay within Earth’s interior contributes to thermal convection in the mantle. Plate tectonics can be viewed as the surface expression of mantle convection.
