Answer
The marine chronometer was not useful for land travel because it was designed to keep accurate time at sea, where the effects of gravity and magnetic fields can cause clocks to run fast or slow. However, the marine chronometer was a critical tool for navigation at sea, as it allowed sailors to determine their longitude and keep track of their position.
