; Geographic Landmarks
: '''The Grand Canyon''' → A perfect "Time Machine" showing millions of years of the Lithosphere carved by the Hydrosphere.
: '''The Amazon Rainforest''' → A "Biome" so large it creates its own "Atmosphere" and weather patterns.
: '''The Ring of Fire''' → A path along the Pacific Ocean characterized by active volcanoes and frequent earthquakes.
: '''The Sahara Desert''' → Showing the power of "Wind" and "Aridity" to transform an entire continent.
