Which of the following is a precise system of grid lines used to describe locations?

The correct answer is a coordinate system, which refers to a precise framework that uses a set of grid lines to specify locations on the Earth's surface. Typically, this involves the use of latitude and longitude, which creates a grid that can accurately pinpoint any location globally. Latitude lines run parallel to the equator, while longitude lines run from pole to pole, intersecting at right angles to create a comprehensive network.

This system is essential for navigation, mapping, and geographic information systems (GIS), as it provides a standardized method for identifying positions. The clarity and precision afforded by a coordinate system enable various applications, from global positioning to cartography, thus facilitating a better understanding of spatial relationships and geographic information.

In contrast, geographical features refer to the physical characteristics of the Earth's surface, such as mountains, rivers, and valleys. A scale model is a representation of an object or area that is proportionally reduced or enlarged, but it does not provide a systematic way to describe locations. A land use pattern describes how land is utilized in a particular area, such as residential, commercial, or agricultural use, and does not involve a formalized grid system for location identification.
