a. The transition zone occurs below the floor of the ocean.
b. The transition zone cannot occur with the warm temperatures associated with high latitudes.
c. There is no transition zone between the warm, low-density surface water and the warm, lowdensity deep water.
d. There is no transition zone between the warm, low-density surface water and the cold, highdensity deep water.
e. There is no transition zone between the cold, high-density surface water and the cold, highdensity deep water at high latitudes.
Answer: e. There is no transition zone between the cold, high-density surface water and the cold, highdensity deep water at high latitudes.

In 2010, geologists working for the U.S. military operations in Afghanistan discovered a literal treasure trove of mineral deposits with a preliminary estimated value at nearly U.S. $1 trillion. So far, no proposals have been made for extracting these resources, but already parallels have been drawn to the many dimensions of human rights issues that have plagued coltan production in the Congo, oil drilling in Nigeria, and the "blood diamonds" of Sierra Leone. The U.S. Agency for International Development (USAID) manages a program called the Mining Investment and Development for Afghanistan Sustainability (MIDAS) project, whose goal is to assist the Afghan government in responsibly developing the nation's mining industry.
For the Afghan people, which of the following would be the most useful benefit from mining profits?
The radioactive element Unobtanium-189 (Ut-189) decays to the stable element Dilithium-171 (Di-171). The half-life of Ut-189 is 10 million years. Using a very sensitive atom-counter instrument, you determine that a mineral sample has 150 atoms of Di-171, and 50 atoms of Ut-189. Assume that no atoms have been lost due to metamorphism over the lifetime of the rock.Use this information to answer the following question.What is the age of the mineral?
A. 10 million years old B. 20 million years old C. 30 million years old D. 40 million years old
