Answer to Question 1

The geothermal gradient is an increase in temperature with depth, which varies from place to place, averaging about 25C per kilometer in the upper crust. A typical geothermal gradient is compared to the melting point curve for the mantle rock peridotite; the temperature at which peridotite melts is higher than the geothermal gradient. Thus, under normal conditions, the mantle is solid.

Answer to Question 2

C

There can actually be a 25-hour time difference between certain locations in the world. The International Date Line passes between the islands of Samoa and American Samoa. It is not a straight line, but "zig-zags" around various island chains. Therefore, Samoa and nearby islands have one date, while American Samoa and nearby islands are one day behind. Daylight saving time is used in some islands, but not in others—further shifting the hours out of sync with natural time.

Prostaglandins were first isolated from human semen in Sweden in the 1930s. They were so named because the researcher thought that they came from the prostate gland. In fact, prostaglandins exist and are synthesized in almost every cell of the body.
