   How do scientists describe Earth's history?

   • To describe Earth’s vast history, scientists use a geologic timescale. They divide it into long segments of time called eras. Each era is further divided into periods.

   How long did the earth exist before the impact?

   • The radiometric ages show the Earth existed already for at least 10 million years before the impact, enough time to allow for differentiation of the Earth's primitive mantle and core. Then, when the impact occurred, only material from the mantle was ejected, leaving the Earth's core of heavy elements untouched.
