The Earth and the Moon are two space bodies that have each other as the closest to one another. Both of them have their own gravitational pull, with the one of the Earth being much greater, while the one of the Moon being weaker than it is expected for a body of its size. Nevertheless they influence each other with the gravitational pull, which is most noticeable on Earth.
The gravitational pull between these two space bodies is the greatest when they are the closest to each other, while it is the smallest when they are the furthest from each other. On January 10 the distance between Earth and the Moon is the smallest and it is 360,048 km, so the gravitational pull is the greatest on this date. On December 19 the distance between Earth and the Moon is the greatest and it is 406,276 km, so the gravitational pull is the smallest.
The era is characterized by having one of the most diverse environment that the earth could have ever seen, as there were number of species of dinosaurs and there were different plant life as well, and the climate was not so cold to live for the different organisms.
As, the life on earth flourish even there were organisms found on large scale inside the arctic circle.While, the level of CO₂ increased inside the Mesozoic era. Along , with which the extinction of about 96 percent of life made it very difficult for the rest of the organisms to survive and thus there were now mutations happening inside the different organisms genome.Along, with that the way of reproduction was greatly changed inside the plants, as more effective form of flowering plants were evolved.
As, for the animals new species with the increase level of survival instinct were evolved from old simple ones across the globe.
