PROBLEM: This region experiences a type of fog that is known as camanchaca. The main river that passes through this area is the Loa River. This region is bound on the west by the Cordillera de la (*) Costa and on the east by the Cordillera Domeyko. For 10 points, name this location often considered to be the driest on the Earth, which runs alongside the Andes Mountains and is a desert located in northern Chile.

SOLUTION: Social Science

PROBLEM: The relationship between temperature and this quantity is given by the Steinhart-Hart equation. Tunnel diodes have a negative value for this quantity, whose changes are measured by the most common type of strain gauge. The proximity and skin effects cause increases in this quantity with increasing frequency. The time constant tau is equal to indudctance divided by this quantity in an RL circuit. An unknown value of this quantity can be determined with a Wheatstone bridge. This quantity is the real part of impedance in AC circuits, and it is equal to voltage divided by current. For 10 points, name this opposition to the flow of current that is measured in ohms.

SOLUTION: Science

PROBLEM: The 90,000 species in this clade are traditionally divided into the paraphyletic class Adenophorea and the more natural class Secernentea. Free-living members can be found in moist soil and in decomposing organic matter on lake and ocean bottoms, where they play an important role in decomposition and nutrient cycling. This clade also includes parasitic members such as Ascaris lumbricoides, which infect over 1. 5 billion people, and Trichinella spiralis, the causative agent of trichinosis. For 10 points, identify this pseudocoelomate worm phylum whose most famous member is, the hermaphroditic model organism with exactly 959 somatic cells, Caenorhabditis elegans.
