How did Mars go from having oceans, rivers, and lakes of liquid water on its surface to the permafrost-like state its surface is in now? (Put the steps in chronological or cause-and-effect order by entering the number 1 for the first step, 2 for the second, 3 for the third, and 4 for the last.)

1. Magma forced intrusion melted the ice and made pathways.

2.Tectonic deformation caused open fractures

3. Icing induced pressurization

Basal melting made up serious pressure and burst the Cryosphere

4 .Meteoric impact

Hypothesis testing: Currently there is not enough data to agree to the fact or disagree the hypothesis. But a long line of missions, with landers and rovers, has been planned
