The term "highest" refers to the measurement of vertical distance from a base point to the top of an object or location. In geography, it often describes mountains or structures, such as the Mount Everest, which is the tallest mountain in the world, reaching an elevation of 8,848 meters (29,029 feet) above sea level. In architecture, "highest" can refer to buildings, with the Burj Khalifa in Dubai being the tallest man-made structure, standing at 828 meters (2,717 feet). These measurements help compare the relative heights of various natural and artificial formations.
