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.

Questions: Put answers to the side.



  1. Which statement best supports the theory that all the

continents were once a single landmass?

(1) Rocks of the ocean ridges are older than those of the

adjacent sea floor.

(2) Rock and fossil correlation can be made where the

continents appear to fit together.

(3) Marine fossils can be found at high elevations above

sea level on all continents.

(4) Great thicknesses of shallow-water sediments are

found at interior locations on some continents.
2. According to the Earth Science Reference Tables, for the

last 200 million years, continents on opposite sides of the

Atlantic Ocean have generally

(1) been drifting closer together

(2) been drifting farther apart

(3) remained the same distance apart

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

(1) the Earth had two different north magnetic poles when the rocks formed

(2) magnetic minerals do not indicate the direction of the north magnetic pole

(3) the continents have moved since the time the rocks were formed

(4) an error was made in determining the age of the rocks

4. According to the Earth Science Reference Tables, the border between the South American plate and the African plate is best described as

(1) converging and located at an oceanic ridge

(2) converging and located at an oceanic trench

(3) diverging and located at an oceanic ridge

(4) diverging and located at an oceanic trench

Base your answers to questions 5 and 6 on the diagrams below of geologic cross sections of the upper mantle and crust at four different Earth locations, A, B, C, and D. Movement of the crustal

sections (plates) is indicated by arrows, and the locations of frequent earthquakes are indicated by •. Diagrams are not drawn to scale.



5. Which location best represents the boundary between the African plate and the South American plate?

(1) A (3) C

(2) B (4) D


6. Which diagram represents plate movement associated with transform faults such as those causing California earthquakes?

(1) A (3) C

(2) B (4) D
7. Many early mapmakers thought Earth’s continents had moved based on ____.

1

plate boundary locations

3

climatic data

2

fossil evidence

4

matching coastlines






8. Continental drift was not widely accepted when it was first proposed because ____.

1.

Wegener couldn’t explain why or how the continents moved

2.

continental landmasses were too big to move slowly over Earth’s surface

3.

magnetic and sonar data proved that Wegener’s hypothesis was incorrect

4.

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.
