THANK YOU ALL!!! YOU ROCK!!!!!!
1) Latitude measures the mileage from the equator and logitude measures the mileage from the prime meridian in London. Sailors can tell how many miles away from London by the latitude and longitude markers all over the world.
2) Remote sensing is the use of radio controled devices to go out and measure mileage and place latitude and longitude markers.
3) GPS is the Global Placemarker System and works by remote sensing satellites that can compare where a GPS reciever is broadcasting from with the nearby latitude and longitude markers and send a signal back that tells you where you are.
4) Mount Everest has been measured with a tape measure in 1928 by Admiral Byrd, in 1952 by plumb bob from the Soviet satellite Jarvik IV, and in 2001 by remote sensing from America’s Skylab.
5) Sonar is Sound Originating Naval Onbord Radar, and is used to bounce radar signals off the ocean floor so satellites can recieve the signals to make maps.
6) Ancient explorers used speculums to see further and released captured sea gulls to see which way they flew to the nearest land.
