Detailed explanation-1: -Which statement best explains how the continents have changed over the last 200 million years, according to the continental drift hypothesis? They split apart from a supercontinent and very slowly moved to their current positions.
Detailed explanation-2: -About 200 million years ago, all the continents on Earth were actually one huge “supercontinent” surrounded by one enormous ocean. This gigantic continent, called Pangaea, slowly broke apart and spread out to form the continents we know today. All Earth’s continents were once combined in one supercontinent, Pangaea.
Detailed explanation-3: -Plate tectonics is the theory that Earth’s land masses are in constant motion. The realization that Earth’s land masses move was first proposed by Alfred Wegener, which he called continental drift.
Detailed explanation-4: -Which statement describes one of Wegener’s ideas that contributed to the theory of continental drift? The continents were once connected as one landmass.
