explain the 3 theories about the formation of the continents
Answer (1)
Continental Drift:This theory, first proposed by Alfred Wegener, suggests that continents have moved over geological time, originally forming a supercontinent called Pangaea. Seafloor Spreading:This theory, developed in the 1960s, explains how new oceanic crust is created at mid-ocean ridges, pushing older crust away and contributing to continental movement. Plate Tectonics:This theory combines the concepts of Continental Drift and Seafloor Spreading, proposing that the Earth's lithosphere is divided into rigid plates that move and interact, causing various geological processes like mountain building, earthquakes, and volcanic activity.
