Process of Science: How can we test hypotheses about something that is postulated to exist in the past but that no longer exists today, such as free-flowing water on Mars?
 
  What will be an ideal response?

Answer to Question 1

A hypothesis must make predictions that are testable today, even if it concerns something that happened in the past. In the case of water on Mars, we would expect geological and mineralogical signatures to persist after the water has sublimated or otherwise disappeared and, indeed, orbital imagers and ground rovers have found several features that support the hypothesis.

Answer to Question 2

FALSE
