Around 71 percent of the Earth's surface is covered in water, which is why geographers have coined so many names to describe the forms it takes. But what’s the real difference between, say, a lake and a pond, a spring and an oasis, or a creek and an arroyo?

Vox gets granular with geography in the video below, explaining the subtle distinctions between everything from a bay (a part of an ocean, surrounded by water on three sides) to a barachois (a coastal lagoon, separated from the ocean by a sand bar). The five-minute explainer also provides maps and real-life examples, and describes how certain bodies of water got their names. (For example, the word geyser stems from geysa, meaning "to gush.")

Guess what? A geyser is also a type of spring. Learn more water-based trivia—and impress your nature-loving friends the next time you go camping—by watching the video below.
