How can you find your approximate latitude and longitude at sea?

Answer 1

Longitude lines are the lines going vertically across the earth, east and west of the Prime Meridian. Latitude lines are the lines going horizontally across the earth, north and south of the equator.

Answer 2

You can find your approximate latitude using a sextant to measure the angle of the sun or the North Star above the horizon. For longitude, you need an accurate clock to determine the time difference between noon at your location and Greenwich Mean Time (GMT) since Earth rotates 15 degrees longitude per hour. By combining your latitude and longitude measurements, you can plot your position on a nautical chart.
