Final answer:
The remote-sensing technology that uses laser beams to penetrate heavy forest vegetation, providing high-resolution images of hidden archaeological features, is called LIDAR.
Step-by-step explanation:
The remote-sensing technology that uses laser beams to penetrate heavy forest vegetation, providing high-resolution images of hidden archaeological features, is called LIDAR (Light Detection and Ranging).
LIDAR works by emitting laser beams and measuring the time it takes for the beams to bounce back after hitting an object. By analyzing the patterns of these laser reflections, LIDAR can create detailed images of the Earth's surface, even in areas with dense vegetation. This technology has been used to discover and map hidden archaeological sites, as it can penetrate through trees and underbrush to reveal hidden features.
