Geographic coordinate system, EssaySextant- allowed users to determine their latitude to within a sea mile or two The gnomon or sun-shadow disk- operated like a sundial, enabling the user to determine his latitude by the length of the suns shadow cast on a disk floating level in irrigate.The Arabian kamal- a rectangular plate that one moved closer or farther from ones face until the distance between the North star and the horizon merely corresponded to the plates upper and lower edges. The distance the plate lay away from the facemeasured by a string tied to the center of the plate and held at the other end to the tip of the nosedetermined the latitude. cross staffTools used to measure longitude (Lesson 02.01) (use the first resource in this lesson to tending you) Be able-bodied to list and describe the 2 main pawns used to measure longitude in early navigation the chronometer- the sextant to figure longitude using the lunar-distance methodCurrent Navigation Tools (Lesson 0 2.01)What tool do we currently use to determine location (latitude and longitude)?The Global Positioning System,Longitude and Latitude (Lesson 02.01)Know the ways that longitude and latitude run (N to S or E to W) and what they measure Longitude E to W know how far east or west they were of the Prime Meridian Latidude N to S how far north or south they were from the equatorWhat are longitude and latitude measured in?they measure in degreesChallenger Expedition (Lesson 02.02)Best resource link to use = Account of the travel of the Challenger Besides conducting sampling of the waters on its journey, what were the main findings from the Challenger voyage? found many new species, and provided collections for scores of biologists.
