Continental drift is a scientific theory that suggests the Earth’s continents were once joined together as a single landmass, which separated and moved to their current positions over time. Proposed by Alfred Wegener in 1912, the theory is based on evidence including the shapes of coastlines, distribution of fossils, and rock formations.
Scientific theory proposing that Earth’s continents move slowly across the planet’s surface over geological time Continental drift is the scientific theory that Earth’s continents were once joined together as a single landmass and have gradually moved apart over millions of years. The concept was first systematically proposed in 1912 by the German scientist Alfred Wegener, […]
Plate tectonics is the scientific theory that explains the large-scale motion of Earth’s lithosphere, the rigid outer shell of the planet. This theory, developed in the mid-20th century, revolutionized geology by providing a unifying framework for understanding earthquakes, volcanoes, mountain building, and the distribution of continents and oceans.
