Name__________________________________ Where in the World was Lystrosaurus?
(And Cynognathus, Glossopteris, and Mesosaurus, too!) For each of the following life forms, plot the coordinates on the map in a different color. Be sure to put the key on the map in that color with the organism’s name. After you have done that, shade around the points, showing the approximate areas where that organism lived.
3. Igneous rocks of the same age have been found on different continents. Magnetic minerals in these rocks indicate different locations of the north magnetic pole. The best explanation for this observation is that
continental landmasses were too big to move slowly over Earth’s surface
magnetic and sonar data proved that Wegener’s hypothesis was incorrect
mantle convection currents weren’t in motion at that time
9. Which is the best evidence supporting the concept of ocean floor spreading?
(1) Earthquakes occur at greater depths beneath continents than beneath oceans.
(2) Sandstones and limestones can be found both in North America and Europe.
(3) Volcanoes appear at random within the oceanic crust.
(4) Igneous rocks along the mid-oceanic ridges are younger than those farther from the ridges.
Continental Cut Out:
Shade the fossil ranges for Lystrosaurus, Mesosaurus, Glossopteris, and Cynognathus onto the continent shapes. Cut them out and glue them onto this paper so that the fossil ranges connect from one land mass to the next.
