I’ve never been but isn’t it like the “city of love” or something?
Answer:
Let's take, Michigan 200 million years ago. Average carbon dioxide levels would have been 1850 parts per million which means that global temperatures would average 3 degrees warmer than today. Michigan was positioned between the cold sea current to the west and mountain ranges to the east (as tall as the Himalayas are today). So the climate in Michigan at this time must have been an extremely arid desert.

Answer:
Option (A)
Explanation:
The cretaceous period formed the last period of the Mesozoic era, marked by the occurrence of some distinct major events, and it began about 145 million years ago and ended by about 65 million years ago. The name Cretaceous is actually derived from the Latin word 'Creta' which means “chalk”. Chalk usually refers to the white colored, soft, powdery limestone rock that is primarily comprised of fossil shells. These are basically dominated by the calcite minerals.
By the end of this period, the dinosaurs were completely wiped out from the earth and the flowering plants started to evolve after the mass extinction event, which is commonly known as the Cretaceous-Tertiary boundary (K-T boundary).
Thus, the name Cretaceous was given because during this time period, there was abundant deposition of marine limestones (chalk), depicting that the sea level was comparatively higher than the present day.
Hence, the correct answer is option (A).
