In which application can KMZ files be opened and utilized?

KMZ files are a compressed version of KML files, which are used for representing geographic data in an XML format. Google Earth is specifically designed to work with KML and KMZ files, allowing users to visualize geographical information and manipulate it in a 3D environment.

When you open a KMZ file in Google Earth, you can view locations, paths, polygons, and other geographic information represented by that data. This functionality makes Google Earth the ideal application for utilizing KMZ files, as it can interpret the intricate details contained within these files, such as layers, imagery, and annotations.

Other applications like Google Maps can display KML files but do not have the same functionality as Google Earth when it comes to KMZ files. Additionally, Google Sites and Google Docs are not designed for geographical data visualization; therefore, they do not support the features necessary to open or utilize KMZ files effectively.
