| This rock is formed from plankton deposits that become low-magnesium calcite, in contrast to other limestone varieties with high magnesium. When ground into a fine powder, this rock is used as a mild abrasive, which increases the ability to grip. For the point, name this sedimentary rock that is used by teachers to write on namesake boards. | Chalk (prompt on “Limestone” or “Calcite” before mentioned) |
| Priests in this country developed the first known solar calendar, which was fixed around the yearly arrival of Sirius. A series of mastabas were arranged into a tomb in this country by the engineer Imhotep. For the point, name this country where ancient scientists wrote their discoveries on papyrus, which were stored in the Library of Alexandria. | Arab Republic of Egypt |

For the point, name this NASA probe that is currently studying the distant edge of the solar system, flying by Pluto in 2015. | New Horizons |
| One of these elements is uniquely explosive in low temperature water, making it the most reactive metal. A beam of that example of these elements is used in fountain atomic clocks, and these elements are located between the noble gasses and similarly-named earth metals. For the point, name this group of elements that includes potassium and sodium. | Alkali Metals (accept Group 1; accept Lithium Group; do NOT accept or prompt on “Earth Metals” or “Alkalines”) |
