The GPS is a system of 24 satellites that all work together to create an exact view of Earth. Using advanced technology, these satellites compare one location to a grid of numbers and then find a location, to a great degree of accuracy! 1. Physical maps show the shapes of the landmasses and water bodies. • They use a system of colors to indicate the height of the land surface. 2. Political maps show the countries, their provinces, and the main cities. 3. Theme maps provide information about specific topics such as population, climate, and resources. • The parallels – also known as `lines of latitude` are horizontal lines that start at the equator • The equator is the line that divides the Earth into two hemispheres: the North Hemisphere and the Southern Hemisphere. • Latitude is measured from 0° to 90°N in the Northern Hemisphere and 0° to 90°S in the Southern Hemisphere. • The meridians – also known as `lines of longitude` -are vertical lines that form half-circles connecting the North and South Poles. • The prime meridian divides the globe into two hemispheres: the western hemisphere and the eastern hemisphere. • Longitude is measured from 0° to 180°E in the Eastern Hemisphere and 0° to 180°W in the western Hemisphere. • If we combine the lines of latitude and longitude we get a grid (a network of intersecting lines). • These intersecting lines are coordinates (intersecting lines) was developed to locate places with precision on the surface of the globe. http://www.infoplease.com/p/bra inpop/latitudeandlongitude.html
