Base your answer to this question on the diagram below, which shows a portion of Earth’s interior. Point A is a location on the interface between layers.
The temperature of rock at location A is approximately
Correct Answer Number: 3
Explanation: To find this answer go to p.10 of the reference tables (Inferred Properties of the Earth's Interior). Locate point A in the reference tables’ chart. Point A can be found on the border of the asthenosphere (plastic mantle) and the stiffer mantle. This line is the second vertical dotted line found on the graphs below the chart. Going to the bottom graph on p.10, Point A has a depth of 600km. Now, using the actual temperature curve follow 600km up until in comes in contact with the curve. Follow the point to the left where temperature can be found. The best answer is 2600oC.
