Direction is the point towards which you are looking or moving. The cardinal directions of the compass are: north, south, east and west. Northeast, northwest, southeast and southwest are known as intermediate points. It is a more reliable method of determining direction. Its needle points to the magnetic north pole. It is divided into 360 parts called degrees (°). The degrees are numbered in a clockwise direction starting from north (0°). A map represents a part of the real surface of the Earth. An atlas is a reference book containing many maps. Symbols and colors are used to show the main features on a map. A legend (key) of the map is used to interpret unknown symbols. A symbol is something that represents or stands for something else. Mapmakers tend to use the same system of symbols on all maps they make. These are called conventional symbols. 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. Lines of latitude They are also known as parallels. They run horizontally. The equator is 0° Latitude. 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. Lines of longitude: They are also called Meridians These lines run vertically. These vertical lines form half-circles connecting the North and South Poles. The prime meridian is 0° longitude and divides the globe into two hemispheres: the western hemisphere and the eastern hemisphere. There are 180° of east longitude and 180° of west longitude. 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/brainpop/latitu deandlongitude.html
