Latitude definition earth science. More precise measurement of latitude requires an understanding of the gravitational field of the Earth, either to set up theodolites or to determine GPS satellite orbits. Source for information on Latitude and Longitude: The Gale Encyclopedia of Science dictionary. This circulation is integral to understanding how temperature variations at the poles influence global weather patterns and climate conditions. We would like to show you a description here but the site won’t allow us. Degrees: Latitude is measured in degrees, ranging from 0° at the equator to 90° at the poles (North Pole at 90°N and South Pole at 90°S). Longitude is a similar measurement east or west of the Greenwich meridian. Measuring latitude lines with high degrees of accuracy is but one component of geodesy, the science of accurately measuring and understanding the Earth's geometric shape, orientation in space, and gravity field. The reason comes down to geometry. Of all the solar energy that reaches the top of the atmosphere, about 47% is absorbed by Earth’s surface, 19% is absorbed by gases in the atmosphere, and the rest is reflected back to space by clouds (23%) and the surface itself (7%). The study of the figure of the Earth together with its gravitational field is the science of geodesy. djyagkdnrlxfbdgnydvwnxqnkawjxomgksmogoybihhhwdmf
