Students will use hands-on learning to better understand what tectonic plates are, how they move, and what their movements cause. Ocean Trenches Ocean trenches form where a plate with a leading edge of oceanic lithosphere collides with another plate.
Click for larger map. The point on the seafloor where the colliding plates are in contact is normally considered to be the geographic location of the plate boundary.
The boundary between the North America Plate and the Eurasian Plate is an example of a divergent boundary at a mid-ocean ridge.
In these situations, an oceanic plate normally subducts into the mantle, forming a topographic low on the ocean floor. Lesson on how to navigate on Google Earth - Pairs of students need a computer to open Google Earth - Demonstrate and have students practice zooming in and out, turning earth, adjusting angle of view, searching for specific location, etc.
Write responses on chart paper B. These types of boundaries must be plotted on a map showing their approximate locations. More Plate Tectonics Maps Here are two plate tectonics maps which show more detail than the maps above. Well-defined boundaries include mid-ocean ridges and ocean trenches.
The southern edge of the Caribbean Plate, passing through northern South America, is an example.
Students use Google Earth to explore earthquakes, volcanoes, and their locations. All of the plate boundaries that occur down the center of the Atlantic Ocean are divergent boundaries that follow the crest of the Mid-Atlantic Ridge.
Students will better understand the effects of plate tectonic movement. Locations where plates are spreading divergent boundaries are shown in yellow. Map showing the geographic location of major ocean trenches in the Pacific Ocean. New lithosphere is created by volcanic activity along the crest of the ridge, and the plates on either side of the ridge are moving away from one another.
Map showing the geographic location of major mid-ocean ridges. Van der Grinten projection. Each student in the pair must find one of each and record on organizer My Choice of Geologic Features G.
Illustration prepared by the United States Geological Survey. Group comes up with one response to share with class, but ALL write response on Question sheet.
A map of the tectonic plates of the earth showing the different boundary types in different colors. Poorly Defined Boundaries Some plate boundaries are poorly defined by topographic expression or lithospheric discontinuities.
Scotia Plate South American Plate A generalized diagram showing the lithospheric situation associated with the formation of convergent, divergent, and transform plate boundaries. And, locations where plates are sliding past one another are shown in orange.
This map was prepared by the National Park Service. A map of global tectonic and volcanic activity over the last one million years, showing: By viewing Google Earth, students will deduce and explain why most earthquakes and volcanoes occur near plate boundaries.
Illustration prepared by Paul D. June 24, Objectives: Map by the United States Geological Survey. These boundaries are usually well enough defined that they can be plotted on a map at a reasonably accurate location.
Through teacher-guided discussions and activities and student explorations, students will have the opportunity to learn how to navigate in Google Earth to see landscape features of the Earth and to focus on earthquakes and volcanoes to realize that they form due to the movements of tectonic plates.
They will do so mostly by interacting with Google Earth. Locations where plates collide convergent boundaries are shown in red. Students get laptops and go to website for animations of each type of plate movement. Mid-Ocean Ridges Mid-ocean ridges are divergent boundaries where convection currents in the mantle lift the ocean floor and produce a rift in the lithosphere that follows the crest of the ridge.3!
TheSidebar.!Thisisa!seriesofpanels(Search,Places,Layers),locatedontheleft sideofyourwindow,!mint-body.com! Oct 18, · Uses freely available Google Earth overlays to visualise and analyse the spatial patterns associated with plate boundaries and earthquake prevalance.
Students will better understand the effects of plate tectonic movement.
By viewing Google Earth, students will deduce and explain why most earthquakes and volcanoes occur near plate boundaries.
Students will become familiar and/or more proficient at using Google Earth to study Earth’s geography and geology. May 03, · For science teachers. A tour around the earth showing geologic plates with boundaries. Animation by Google Earth. Video and copyright by Scott Brande To crea. Introduction to Plate Tectonics via Google Earth Reconstructions of the Earth’s tectonic plate locations through time are available, for example, at: To do this, you’ll use the program Google Earth, and Google Earth layers compiled from various sources.
