To which geographic concept does this statement apply? Mount Everest is the highest mountain In the world.

Mount Everest is the highest elevation on Earth. It rises 8,848 meters (29,029 feet) above sea level. A devastating 2015 earthquake shifted the mountain about 3 centimeters (1.2 inches) to the southwest, but had no impact on its elevation. Mount Everest is part of the Himalaya mountain range, which separates the bulk of the continent of Asia from the Indian subcontinent. The Himalayas are spread across five countries: Bhutan, China, India, Nepal, and Pakistan. Mount Everest is a part of two nations: China and Nepal. The traditional Chinese name of Mount Everest is Chomolungma. The traditional Nepalese name is Sagarmatha. A British surveyor, Sir Andrew Scott Waugh, gave Mount Everest its English name in 1865. He named it after Sir George Everest, a Welsh geographer. Although Mount Everest is the highest elevation on Earth, it is not the tallest mountain. Mauna Kea, on the island of Hawaii in the U. S. state of the same name, rises not from a continental mountain range, but from the seafloor. Mauna Kea rises 4,207 meters (13,803 feet,) above sea level. From base to summit, however, Mauna Kea is 9,966 meters (32,696 feet) tall! Mount Everest, and even Mauna Kea, are far from the highest mountains in the solar system. The highest mountain in the solar system is probably Olympus Mons, a volcano on Mars. Olympus Mons rises about 22 kilometers (14 miles) into the Martian atmosphere. (That's 22,000 meters, or 72,178 feet-more than twice the height of Mount Everest!)
