Geopolitical Analyst — Lesson 2
Lesson 2 covers the fundamental properties of Earth's surface distribution and tectonic dynamics, incorporating the total land area of approximately 148.9 million square kilometers (29.2% of Earth's surface), water covering the remaining 70.8%, and the distribution of land across seven continents and major ocean basins. It includes plate tectonics—the unifying theory of Earth science explaining earthquakes, volcanoes, mountain ranges, and ocean basins—where Earth's lithosphere is divided into approximately 15 major tectonic plates and several smaller ones moving at rates of 1–10 centimeters per year.
