What's the Difference Between a Lake and a Pond?

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.

Laser-Cut Wood Maps Showcase World Cities

You can already express your love for your local geography with a chocolate map or a custom-designed poster. The latest material for immortalizing your home city is laser-cut wood. As Curbed reports, CityWood is a line of striking, minimalist maps currently raising funds on Kickstarter. (The campaign has blown past its original $3000 goal by raising more than $73,000 so far—and counting.)

CityWood offers maps of nearly 100 cities, including New York, Los Angeles, London, and Tokyo. The waterways and city streets of each location are engraved into high-quality plywood using a laser cutter. The map is then put together by hand, and packaged inside a wood frame behind plexiglass.

Customers have their choice of sizes, from a small 5-inch-by-7-inch map for their desk to a 36-inch-by-36-inch display for their wall. Prices range from $29 to $439.

To preorder a CityWood map of your own, you can pledge to the product’s Kickstarter before the campaign ends on February 16. CityWood is also accepting votes on new cities to add to its lineup.

This 1940 Film on Road Maps Will Make You Appreciate Map Apps Like Never Before

In the modern era, we take for granted having constantly updated, largely accurate maps of just about every road in the world at our fingertips. If you need to find your way through a city or across a country, Google Maps has your back. You no longer have to go out and buy a paper map.

But to appreciate just what a monstrous task making road maps and keeping them updated was in decades past, take a look at this vintage short film, "Caught Mapping," spotted at the Internet Archive by National Geographic.

The 1940 film, produced by the educational and promotional company Jam Handy Organization (which created films for corporations like Chevrolet), spotlights the difficult task of producing and revising maps to keep up with new road construction and repair.

The film is a major booster of the mapmaking industry, and those involved in it come off as near-miracle workers. The process of updating maps involved sending scouts out into the field to drive along every road and note conditions, compare the roads against topographical maps, and confirm mileage figures. Then, those scouts reported back to the draughtsmen responsible for producing revised maps every two weeks. The draughtsmen updated the data on road closures and other changes.

Once those maps were printed, they were "ready to give folks a good steer," as the film's narrator puts it, quietly determining the success of any road trip in the country.

"Presto! and right at their fingertips, modern motorists can have [information] on any road they wish to take." A modern marvel, really.
