Question

suppose you find a meteorite on the ground. how could you tell its age? use radiometric dating, probably with potassium & argon ratios measure its size & determine how much it has melted before resolidfying determine the age of the rock strata it was discovered in. you can only determine its age if its a \meteor - wrong\ (an earth rock mistaken for an extraterrestrial one).

Explanation:

Radiometric dating is a well - established method for determining the age of rocks and meteorites. Potassium - argon dating is one such radiometric technique. Measuring size and melting history doesn't directly give age. The age of rock strata it's found in gives the age of the strata, not necessarily the meteorite. And meteorites can have their age determined regardless of whether they are misidentified Earth rocks or not.

Answer:

Use radiometric dating, probably with potassium & argon ratios
