Oxygen, silicon, aluminum, and iron account for 88.1% of the mass of the Earth’s crust, while another 90 elements make up the remaining 11.9%. The Earth’s crust comprises about 95% igneous and metamorphic rocks, 4% shale, 0.75% sandstone, and 0.25% limestone. Most elements are found in only trace amounts within the Earth’s crust, but several are abundant. The crust is a rigid surface containing both the oceans and landmasses. This infographic takes a look at what elements make up this 1%, based on data from WorldAtlas. Representing the remaining 1% is the crust, a thin layer that ranges in depth from approximately 5-70 km (~3-44 miles).

Visualizing the Abundance of Elements in the Earth’s Crust That enduring influence is one of the reasons ancient Rome still fascinates us to this day.įor more reading, check out Trubetskoy’s followup, Roman Roads of Britain. A recent study even points out that proximity to that foundational network of roads even has a strong correlation with economic activity today.īeyond mere curiosity or entertainment, looking back at Roman ingenuity allows us to see the impact their road network had on today’s world. London, Paris, Barcelona, and countless other major cities sprang from Roman settlements along the road network, and even as Europe descended into the Dark Ages (476-800 CE), Roman roads remained as one of few functioning modes of movement and communication. – Sasha Trubetskoy The Enduring Influence of Roman Roads

There’s something alluring about Rome’s ability to carve out such a huge and advanced empire, with a legacy that lasts today. As the first major road network in Europe, the Romans quite literally laid the foundation for development across the continent. This network of roads was vital as it allowed for quick troop movement as well as the development of a mail system. Viae vicinales: These tertiary (often dirt) roads connected villages and areas within districts, eventually linking to the larger network. Viae privatae: Private or country roads were financed by wealthy individuals to connect towns and other noteworthy points to the viae publicae.

These were the main, paved arteries of the empire and often included infrastructure such as drainage, milestones, and way stations. Viae publicae: Public highways or main roads, typically maintained by the military. There were three main types of roads in Ancient Rome: The screenshot below shows the fastest, cheapest, and shortest routes between the settlement of Lutetia (the predecessor of present-day Paris) and Roma. This impressive network is what allowed Rome to exercise control and communicate effectively over such a large territory.įor a detailed look at travel times and costs, check out Stanford’s amazing ORBIS platform. Today’s visualization, by Sasha Trubetskoy, has mashed-up two enduring obsessions – transit maps and Ancient Rome – to help us understand the connection between Rome and its sprawling empire.Īt the height of the Roman Empire, there were approximately 250,000 miles (400,000 km) of roads, stretching from Northern England to Egypt and beyond.

Place names are unfamiliar and roads meander across the landscape making it difficult to see the connections between specific cities and towns.
