“Gibraltar Bay, located near the southernmost tip of the Iberian Peninsula, is the central feature of this astronaut photograph. The famous Rock of Gibraltar that forms the northeastern border of the bay is formed of Jurassic-era seafloor sediments that solidified into limestone, a rock formed mostly of the mineral calcite, which is found in the shells of sea creatures. The limestone was subsequently lifted above the ocean surface when the African and Eurasian tectonic plates collided.”

Questions to Ponder: Why are both Spain and the UK invested in this piece of territory? What challenges are there for a small exclave when neighbors aren’t friendly? How does Spanish and British supranational connections impact this issue?
