🌆 This aerial view of Gustavo A. Madero, northern #Mexico City, highlights how dense urban areas rely on wastewater treatment plants to protect strained water supply and reduce contamination. Essential infrastructure for a growing city. 💧

🏔 Hands up if you fell for this one... #TruthMatters #geographyfun

Beneath the Sahara lies a hidden world of #underground #rivers & aquifers, relics of a time when the desert was a savanna. The largest, the Nubian Sandstone Aquifer System, spans Egypt, Sudan, Chad & Libya, leaving a reminder that even the driest places hold stories of #water.

🎨 Looks like modern art, but it’s actually geography. These vibrant shapes are aerial shots of salt pans in Newark, one of three San Francisco Bay Area towns with colourful salt ponds. ✨ Photo credit goes to @USGS & @googleearth. #geographyfun #art #PhotographyIsArt

🌍 Did you know? Earth’s magnetic north is shifting at around 50–60 kilometres per year, changing the way navigators and GPS systems are calibrated. #KnowledgeIsPower #FactsMatter

Where do YOU think is the hottest place on earth, and why? #busted #Truth

After nearly a decade at the CGA, we bid farewell to Jessica 🌟 From GIS digitiser to Analyst, Short Course Manager & de facto Chief Cartographer, her #impact has been immense. 💙 Thank you, Jess — we’ll miss you & wish you all the #best for the future!

🛰️ On This Day – August 19 In 1964, Syncom 3 became the world’s first geostationary satellite, orbiting Earth at over 35,000 km and staying fixed above the same spot. This breakthrough laid the foundation for today’s satellite-powered services. #geography #satellite

🌍 #DidYouKnow #Earth is slightly flattened at the poles and bulges at the equator due to its rotation — making it an oblate spheroid. This means the distance from pole to pole is a bit shorter than the diameter across the equator.

🌍Did you know about human geography? 🙎🙎‍♂️🙎‍♀️ It explores the relationship between people and places. From #cities and #cultures to migration, #economics, and #inequality, it helps us understand #patterns in society and the #impact of humans on the #environment.

Meet Josh, an intern at the CGA. Josh plays a key role in the @terra_clim project. When he’s not behind a screen, you’ll find him rock climbing, caving, or documenting underground ecosystems—combining a love of nature with a passion for conservation. #Internship #geography
