Longitudes Latitudes q What can we use to

Longitudes & Latitudes q What can we use to show the position of place on the atlas or map? ü We can use latitudes and longitudes to give the position of places on the map q. What are longitudes and latitudes? ü They are imaginary vertical and horizontal lines around the Earth. ü We measure them in degrees and use this to give the exact position of place in the world.

Longitudes & Latitudes q. What are longitudes and latitudes? Ø Lines of longitude are the vertical lines in the world imaginary grid. Ø They go from the North Pole to the South Pole and they are the same length. Ø Lines of latitude are the horizontal lines in the world’s imaginary grid. Ø Lines of latitude are not all the same length.

West East 180 o E and 180 o W are the largest longitude. Australasia The vertical lines (直線) are called longitude (經度). The 0 o is called the Prime Meridian (本初子午線) which passes through Greenwich Observatory (格林威治天文台) near London, England.

S (South Pole 南極) The horizontal lines (橫線) are called latitude (緯度). The 0 o Equator is the longest latitude. It divides the Earth into Northern Hemisphere (北半球) and Southern Hemisphere (南半球). The closer to the Poles, the shorter lines of latitude are.
