Answer to Question 1

Answer: Minerals in the discontinuous series differ from each other in both chemical composition and crystalline structure. For example, olivine is an independent silicate, pyroxene is a single chain silicate, and amphibole is a double chain silicate. Minerals in the continuous series only differ from each other in chemical composition. For example, all minerals in the continuous series are plagioclase. However, they start out as calcium-rich plagioclase and slowly convert to a more sodium-rich plagioclase.

Answer to Question 2

Answer: Crustal rocks at the crust-mantle boundary are already close to their melting point. Contact with the hotter mantle-derived magma will result in melting of the crustal rocks. The two melts will mix, producing a magma that is more silica-rich and lower in density.

There used to be a metric calendar, as well as metric clocks. The metric calendar, or "French Republican Calendar" divided the year into 12 months, but each month was divided into three 10-day weeks. Each day had 10 decimal hours. Each hour had 100 decimal minutes. Due to lack of popularity, the metric clocks and calendars were ended in 1795, three years after they had been first marketed.

Though methadone is often used to treat dependency on other opioids, the drug itself can be abused. Crushing or snorting methadone can achieve the opiate "rush" desired by addicts. Improper use such as these can lead to a dangerous dependency on methadone. This drug now accounts for nearly one-third of opioid-related deaths.
