QUESTION:

They learned that The Moon is not a primordial object; it is an evolved terrestrial planet with internal zoning similar to that of Earth.

• The Moon is not a primordial object; it is an evolved terrestrial planet with internal zoning similar to that of Earth.

The youngest Moon rocks are virtually as old as the oldest Earth rocks. The earliest processes and events that probably affected both planetary bodies can now only be found on the Moon.

The Moon is lifeless; it contains no living organisms, fossils, or native organic compounds

Early in its history, the Moon was melted to great depths to form a "magma ocean." The lunar highlands contain the remnants of early, low density rocks that floated to the surface of the magma ocean.

The surface of the Moon is covered by a rubble pile of rock fragments and dust, called the lunar regolith, that contains a unique radiation history of the Sun which is of importance to understanding climate changes on Earth.

Thanks for watching.
