Where is the center of the earth on a map

• • • • Calculation Methods This page shows how to calculate the geographic midpoint (also known as the geographic center, or center of gravity) for two or more points on the earth's surface. A second method is given showing how to calculate the center of minimum distance **, and finally a third method calculates the average latitude/longitude. There are We will assume that the latitude and longitude data for the calculations comes from a list called 'Your places'. Each location may be weighted in one of three ways: • Weight by time. Use this to specify the amount of time you have lived in each location in order to find the geographic average location for all of the places you have lived in. The time for each location is converted into days, for example: w 1 = years*365.25 + months*0.4375 + days. • Simple weighting factor, such as population for each location can be stored in w 1, w 2 etc. • Equal weight. If no location is to be weighted more than another then set w 1, w 2 etc all = 1. A. Geographic midpoint Note: See this Summary The geographic midpoint is calculated by finding the center of gravity for the locations in the 'Your Places' list. The latitude and longitude for each location is converted into Cartesian (x,y,z) coordinates. The x,y, and z coordinates are then multiplied by the weighting factor and added together. A line can be drawn from the center of the earth out to this new x, y, z coordinate, and the point where the line intersects the surface of the earth...

Incredible Map of Pangea With Modern-Day Borders As volcanic eruptions and earthquakes occasionally remind us, the earth beneath our feet is constantly on the move. Continental plates only move around 1-4 inches per year, so we don’t notice the tectonic forces that are continually reshaping the surface of our planet. But on a long enough timeline, those inches add up to big changes in the way landmasses on Earth are configured. Today’s map, by Pangea: The World As One Pangea was the latest in a line of supercontinents in Earth’s history. Pangea began developing over 300 million years ago, eventually making up one-third of the earth’s surface. The remainder of the planet was an enormous ocean known as Panthalassa. As time goes by, scientists are beginning to piece together more information on the climate and patterns of life on the supercontinent. Similar to parts of Central Asia today, the center of the landmass is thought to have been arid and inhospitable, with temperatures reaching 113ºF (45ºC). The extreme temperatures revealed by By this unique point in history, plants and animals had spread across the landmass, and animals (such as dinosaurs) were able to wander freely across the entire expanse of Pangea. Breaking Up is Hard to Do Around 200 million years ago, magma began to swell up through a weakness in the earth’s crust, creating the volcanic rift zone that would eventually cleave the supercontinent into pieces. Over time, this rift zone would become the Atlantic ...
