KEY - UNIT 7 REVIEW
1. Describe Pangaea.
When all continents were fused together into one super continent
2. Describe Continental Drift.
​When continents broke away from being one land mass and moved to where they are
currently
3. Who is given credit for both Pangaea and Continental Drift? What evidence did he use to
support these? ​Wegener...fossils (reptiles and plants), matching landforms (glaciers and
mountain ranges, South America fit beside Africa like puzzle pieces
4. List the 3 landforms found at CONVERGENT BOUNDARIES (COLLIDE).
​ Mountain, Volcano, Trench
5. List the 3 landforms that are found at DIVERGENT BOUNDARIES.
Sinkholes,
Rift Valley (continental plate separates),
Mid Ocean Ridge (ocean plates separate)
6. Name the landform found at TRANSFORM BOUNDARIES.
​Fault Lines
7. Explain HOW and WHERE NEW crust is formed. Make sure to include the Plate Boundary
type and how plates would have to move.
- ​HOW...when oceanic plates split apart and magma rises up in between
- Where...Mid Ocean Ridges - ….DIVERGENT BOUNDARIES
8. a. Explain WHERE the oldest ocean crust should be found.
​further away from 2 diverging plates, Mid Ocean Ridge
b. What phrase did we use to remember where OLD vs New should be?
​In with the New, Out with the Old
9. a. What CAUSES plates to converge, diverge and transform? ​Convection currents
b. WHERE does this occur in the earth? A
​ sthenosphere
c. Draw the symbol we use to represent this.
​Circle heat rising cold sinking
10. WHERE are plates located in the earth? L
​ ithosphere….”litho” means rock :)
11. Topographic maps shows __​ELEVATION​__ in terms of sea level.
12. What are the lines called in Topographic Map? c​ ontour line​s (pg 24 of your notes)
13. Below, draw what lines should look like for STEEP SLOPES and GENTLE SLOPES. Label
them. ​(Refer to Pg 17 Notes if you need help)
Steep...lines are really close
Gentle Slope...lines are farther apart
14. Draw what contour lines should look like to show that UPSTREAM is on the RIGHT.
.​..draw lines that make a v shape….the point part of “v” should point to the right
15. Where would a DELTA form in the picture you drew for #14. What did I tell you to make it
easier to remember? ​It would be opposite of the V Point, (the left of the mouth)… “DD”..Delta
Downstream
16. Label what Plate Boundaries are represented in A-C. Then write geographical features
resulting from each. *USE your WORD WALL in your notebook!!!
A. Divergent…. mid ocean ridges *Creates New Ocean Crust
B. Convergent Boundary….volcano and trench (specifically subduction)
C. Transform Boundary….Fault lines
17. Label Upstream. Label where a Delta could form.
​Upstream would be toward the EAST.in this pic..point part of “V” points to upstream
​Deltas form downstream...WEST in this picture

19.​ ​*​Write the name of the boundary​ type that would MOST likely create the
landforms listed below.
*​Draw​ the direction that the plates would have to move using ​arrows​.
*Ch​oose 3 different colors​ to represent the 3 Plate Boundaries and ​color all 3
ROWS below ​after grouping appropriately.

ARROWS:
20) ​Answer: 140m (Explanation: 1400(Y)-1260(X) = 140m.
The XY trail is the steepest b/c lines are closer together & elevation changes quicker.

Using the picture above to answer the questions below.
A. Where would ​NEW/YOUNGEST​ ocean floor be found? Circle One:
B. Where would the ​OLDEST​ floor be found? Circle One

22) A river is indicated in the topographic map below. How will the “V” shaped contour lines
change over the years if it created a canyon? ​ Deeper “V” shape will result
23.) Wegener pointed out reptile fossils were found on both sides of the Atlantic Ocean. Explain
how this could happen. ​ Atlantic Ocean did not exist …...b/c South America & Africa were
fused together and there was no ocean between
24. (8.5A) Use a Periodic Table to complete information below about the element Oxygen.
A. Label Atomic # and Atomic Mass. ​ Labeled in diagram below
B. How would you use this information to find the number of Protons, Electrons, and
Neutrons
​Atomic # - Song P.E. Always = PROTONS (P) & Most of the Time ELECTRONS(E)
​Neutrons - Subtract the Atomic # from the Atomic Mass.
*Remember to atomic mass to the nearest whole number before you subtract.
** “.5 or more raise the score and .4 or less let the number rest.
C. What area of the atom has the majority of the mass? ​NUCLEUS
D. Write the electrical charges for each: Nucleus __+ (because the proton’s
charge)__ Proton __+_, Neutron __0 (no charge)_ , & Electron _- (negative) _
