Final answer:
The red lines on the map represent faults. The age of the strata that the town of Cinco is built on can be determined by studying the geologic map. The contour interval of this map can be found in the map's legend. The magnetic declination of this map is also provided in the legend.
Step-by-step explanation:
The red lines on the map represent faults. They are used to show the locations of known faults in the Southeast Quadrant of the Cross Mountain Quadrangle, CA.
The age of the strata that the town of Cinco is built on can be determined by studying the geologic map. The map will show the different rock layers and their ages, allowing us to determine the age of the strata.
The contour interval of the map can be found in the map's legend. The legend will provide information on the vertical distance between contour lines, allowing us to understand the topography of the area.
The magnetic declination of the map is also provided in the legend. It represents the angle between magnetic north and true north. The magnetic declination may change over time due to the movement of tectonic plates.
The name of the fault in the Southeast comer of the map can be found by studying the legend or referring to the accompanying text or notes. The fault may be labeled with a specific name or identified by its location and characteristics.
