How has the climate of northeastern united states changed over the past 200 million years

The USA was probably closer to the equator 200 million years ago. Because it was close to the equator, it was probably a warmer, oceanic environment that had coral reefs. A lot of the Midwest has limestone, which forms in shallow sea environments. There's also lots of fossils that are similar to corals in the Midwest. Once the continent started to move with plate tectonics, the climate changed with it.

Mars and earth have quite a few things in common. both are  terrestrial planets, both are located within the sun’s  habitable zone, both have  polar ice caps, similarly  tilted axes, and similar  variations in temperature. and according to some of the latest scientific data obtained by rovers and atmospheric probes, it is now known that mars once had a  dense atmosphere  and was covered with  warm, flowing water.
