Please use the maps above to find numerous examples of each of the following plate tectonic settings. Please read the legend at the bottom of this Dynamic Planet Map for an explanation of the symbols used. Give the setting a geographic name (e.g., the Andes Mountains, the Mid-Atlantic Ridge, etc.) and specify the tectonic plate(s) involved in each example. The names of the plates can be found on the This Dynamic Planet Map.
The names of linked geologic features are not provided on this Dynamic Planet Map. An atlas will be required to locate these. You may find several geographic atlases online (the link above is for the National Geographic globe atlas), or you can use one that you already have at home. Make sure you get an atlas that includes both the geographic names of land features and the geographic names of ocean floor features. There may be more than one geographic feature connected with some features. The deep-sea trench or the continental volcanic arc, for example, can be used to identify an ocean-continent convergent boundary. Although you only need to identify each scene with one notable geographic characteristic, having more than one will be helpful.
Finally, make a list of the common geologic phenomena or features linked with each type of plate tectonic feature. The following are some examples:
minor shallow tremors
deep, big earthquakes
(hot spot volcanic tracks, volcanic island arcs, or continental volcanic arcs)
trenches in the deep sea
ridges in the ocean (spreading centers)
mountain ranges on the continent (non-volcanic)
Don’t include specific place names or landscape features (such as “Mount St. Helens”); the purpose is to see what all examples of this type of border have in common (such as “deep earthquakes, volcanic island arcs, and deep-sea tunnels”).
On the planet, locate five (5) divergent plate borders (spreading centers). What general geologic features/phenomena are associated with this boundary (e.g., earthquakes, volcanoes, trenches, mountains, etc.)? Keep in mind that not all objects on the map labeled “ridge” are tectonic spreading centers. Name Plates Are Involved Geologic Phenomena/Features
Boundaries That Converge:
Three (3) separate ocean-ocean convergent boundaries should be identified. Make sure to specify which two plates are colliding and which plate is being subducted in the collision. What geologic features or occurrences are linked with this border in general? Name Plates Are Involved Geologic Phenomena/Features
Determine three (3) different convergent ocean-continent borders. Make sure to specify which two plates are colliding and which plate is being subducted in the collision. What geologic features or occurrences are linked with this border in general? Name Plates Are Involved Geologic Phenomena/Features
Identify at least one (1) convergent border between continents. Make a note of which two plates are involved in the incident. What geologic features or phenomena are linked to this line? Name Plates Are Involved Geologic Phenomena/Features
Boundaries Must Be Transformed:
Locate four (4) separate transform faults on the Earth’s surface. What geologic features or phenomena are linked to this line? Name Plates Are Involved Geologic Phenomena/Features
Areas of Interest:
Locate five (4) active hot spots on the Earth’s surface. What geologic features or phenomena are linked to this line? Involvement of a Name Plate Geologic Phenomena/Features
Estimate the percentage of an ocean basin’s perimeter that is made up of deep-sea trenches to see if it is getting bigger or smaller over time. If deep-sea trenches make up more than half of the circumference (>50%), the ocean basin is most certainly shrinking. If deep-sea trenches make up less than half of the perimeter (50 percent), the ocean is expected to grow in size throughout time.
Determine if each of the following oceans or seas is growing or shrinking over time:
The Atlantic Ocean is a large body of water in
The Pacific Ocean is a large body of water in
Ocean of India
The Red Sea
Ocean of the North Pole
