How did scientists discover that rocks farther away from the mid-ocean ridge were older than those near it?

• by observing eruptions of molten material on the sea floor

• by mapping rocks on the sea floor using sonar

• by determining the age of rock samples obtained by drilling on the sea floor

• by measuring how fast sea-floor spreading occurs
