Base your answers to questions 1 through 4 on the generalized map below, which shows a portion of the Atlantic Ocean floor located between South America and Africa. Isolines show the approximate age, in million years, of the ocean-floor bedrock on each side of the Mid-Atlantic Ridge. Points A, B, and X represent locations on the ocean floor.
1. On the grid in your answer booklet, construct a line graph of bedrock age by plotting the age of the bedrock shown by each isoline that crosses line AB. Points A and B are plotted on the grid. Connect the plots from A to B with a line.
2. Estimate the age of the ocean-floor bedrock at point X.
3.
Name:_________________Date: _____________
4. Explain why the age of the ocean-floor bedrock increases as the distance from the Mid-Atlantic Ridge increases.
5. The Mid-Atlantic Ridge separates pairs of crustal plates, such as the South American Plate and the
AfricanPlate. Identify one other pair of crustal plates separated by the Mid-Atlantic Ridge
6. What is the approximate time difference between the first P-wave and the first S-wave recorded at a seismic station located 8000 kilometers from an earthquake’s epicenter?
(1) 8 minutes 40 seconds (2) 9 minutes 20 seconds (3) 11 minutes 20 seconds (4) 20 minutes 40 seconds
7. Which surface feature was produced by crustal movements at a transform plate boundary? (1) East African Rift (3) Tasman Hot Spot (2) Aleutian Trench (4) San Andreas Fault
8. A model of Earth’s internal structure is shown below. Analysis of which type of data led to the development of this model?
(1) seismic waves (2) depth of Earth’s oceans (3) electromagnetic radiation (4) isobar gradients

Base your answers to questions 1 and 2 on the cross section below, which shows the type of seismic waves recorded at various locations after an earthquake has occurred. Point A is a location on Earth’s surface and X is the epicenter of the earthquake.
1. Point A is located 7600 kilometers from the epicenter of this earthquake. How many minutes did it take the first S-wave to reach point A? (1) 9 min (3) 16 min (2) 11 min (4) 20 min
2. How many kilometers did the seismic waves travel from the earthquake directly to the outside of the outer core? (1) 800 km (3) 2900 km (2) 1400 km (4) 6400 km

The Great Rift Valley
Rifting of Earth’s crust in eastern Africa began during the Neogene Period as the Ethiopian and Kenyan Domes formed. These two huge domes were created as Earth’s mantle pushed up the overlying crust. As the crust was forced upward, the resulting tension cracked the crust, resulting in the eruption of volcanoes and the formation of large rifts. The crust continued to pull apart, forming rift valleys. These valleys have become deeper and are currently becoming filled with sediments, igneous rock, and water.
1. How many million years ago did the Ethiopian and Kenyan Domes form? ______mya
2. On the diagram, draw two curved arrows, one on each side of the dashed line, to show the direction of movement of the convection currents within the asthenosphere that caused the formation of the dome and the rift valley near location X.
3. Which two lithospheric plates are separated by a mid-ocean ridge in the northeastern portion of
the Ethiopian Dome? _____________________________________________
4. Which cross section best represents the convection currents in the mantle beneath the Peru-Chile Trench?
