Continental Drift and Plate Tectonics Quiz

Continental Drift and Its Proponent

• Alfred Wegener was the first to publicly introduce the concept of Continental Drift, proposing that continents were once joined and have since drifted apart.

Movement of Earth's Continents

• Wegener referred to the movement of continents as "Continental Drift," suggesting a dynamic process that reshapes the Earth's geography over time.

Earth's Crust Composition

• The Earth's crust is divided into seven large tectonic plates, each representing substantial sections of the planet's surface.

Tectonic Plate Boundaries

• The activity at the boundaries where tectonic plates converge, diverge, or slide past each other is known as tectonic activity, encompassing phenomena like earthquakes, volcanic eruptions, and mountain formation.

Formation of Present-Day Continents

• Present-day continents were formed millions of years ago from a supercontinent known as Pangaea, which gradually broke apart through the process of Continental Drift.
