Which of the following statements is true about atmospheric escape from Mars? (click all that apply)
o While some atmospheric escape could have occurred, much of the previous atmosphere could all be locked up in buried carbonates.
o Argon is the preferred gas to use for isotopic measurements because it is captured through chemical reactions into the measuring instrument.
o Measuring isotopic ratios of different gasses is important because the different isotopes undergo different chemical reactions which trace escape.
o The isotopic composition of the atmosphere implies that substantial loss has occurred.
