Why do people use Earth's motions to determine units of time?

• Clocks, watches, and timers run off the magnetic field created by Earth's motions

• Earth's motions are regular, so people can use them to measure time consistently

• Earth's motions happen to match up with the units used to measure time

• None of the other answer choices
