How do scientists figure out the age of the seafloor?

• They research it from ancient sea maps that trading vessels would use in the 1700s
• They use the moon phases and eclipses to calculate the age
• They use seismographs and the depth as well as location of earthquakes to calculate the age
• They take drill ships to many locations in the oceans and collect, then date, rock samples.
