Briefly explain continental drift and one common misconception about it.

## Continental Drift **The Basic Concept:** Continental drift is the theory that Earth's continents have moved across the planet's surface over geological time. Proposed by Alfred Wegener in 1912, it explains how continents were once joined in a supercontinent called Pangaea (about 300 million years ago) and have since slowly drifted apart to their current positions. ## Common Misconception **"Continents plow through the ocean floor like ships through water"** Many people imagine continents actively moving through stationary ocean crust, but this isn't accurate. Instead, continents are embedded in larger tectonic plates that include both continental and oceanic crust. These entire plates move together due to convection currents in the underlying mantle. The continents are passengers on these plates rather than independent vessels cutting through the seafloor. This refinement led to the modern theory of **plate tectonics**, which replaced and expanded upon Wegener's original continental drift hypothesis.
