4. Similar animals are found on
two continents separated by a
vast ocean.

5. Locations of ancient glaciers
can be traced from one
continent to the next.

Directions: Answer each question on the lines provided.

6. How is the theory of plate tectonics supported by the fact that mountain ranges that formed at similar
times exist on continents that are far apart today?

7. How does similar fossil evidence found on two continents separated by a vast ocean support the theory of
plate tectonics?

Mo11-L1: Key Concept Check

Direction: On the line before each description, write the letter of the term that matches it correctly.
Terms will be used more than once.

1. In this type of plate boundary, the plates slide past each other.

2. New crust forms as molten rock erupts and cools. A. convergent boundary

3. Crust rises and mountains form as plates push together. B. divergent boundary
C. transform boundary
4. Movement at this type of plate boundary forces the denser
oceanic plate down into the mantle.

5. Plate movement at this type of boundary can form a rift on
the ocean f oor.

6. Movement at this plate boundary deforms railways and roads.

7. When two continents collide at this type of boundary, both
continents remain on the surface, forming mountains.

8. Tectonic plates slide horizontally at this plate boundary.

9. This plate boundary often includes a subduction zone.
