Datums. Define the shape and size of the earth. . Reference points on a coordinate system used to map the earth. . . There are hundreds of . datums. currently in use; all are either vertical or horizontal in orientation. . Latitude. Distance measure in degrees- from 0. o. to 90. o. North or South of the equator. Equator- . primary reference point. Lines . are called parallels- form complete circles around the earth; are parallel to the . History. Use of grid lines . originated from. about 300 B.C.E by Greek . astronomers . Hipparcus. and . Ptolemy. Used spherical trigonometry observations using sun, moon, and stars to plot points on a spherical earth. 2. Grid System. Lines of latitude and longitude cover the entire Earth, allowing us to find any location.. The . cardinal directions. are North, South, East and West.. Lines of Latitude run East to West. Globe Skill Review. What is the invisible line at 0. ° latitude called?. The equator is the invisible line at . 0. ° latitude.. The equator is the “belt” of the earth.. What kind of lines show how far a place is away from the equator?. Hemispheres. A place can be either in the NORTHERN or SOUTHERN hemisphere. That means it is in one of the halves above or below the imaginary east-west line known as the EQUATOR.. A place can also be in either the WESTERN or EASTERN hemisphere. That means it is in one of the halves on either side of the imaginary north-south line known as the PRIME MERIDIAN.. Do Now. : Why do you think we call the equator the equator?. HW: Latitude/Longitude practice . ws. . . 4 Hemispheres. The equator splits apart the Northern and Southern Hemisphere. The Prime Meridian and International Date Line split the Eastern and Western.

A . scientific theory. . is a well-substantiated explanation of some aspect of the natural world, based on a body of facts that have been repeatedly confirmed through observation and experiment. Scientists create scientific theories from hypotheses that have been corroborated through the scientific method, then gather evidence to test their accuracy.. Taking the bite out of map reading The World of Geography! Our World Geography is the study of Earth’s Physical Properties An important tool used to study geography is a Map! A Globe is helpful and informative too After . Unit . 4 you should be able to:. Accurately write coordinates. Use a map containing latitude and longitude. Determine latitude using the altitude of Polaris. Determine differences in time zones. Added the . LocationListener. interface to acquire the GPS data.. Added the .
