The history of our Earth is action packed. However, the 3 events that stand out to me the most are the Quaternary Period in the Cenozoic Era, the Jurassic Period, and lastly the Cretaceous Period. The Quaternary Period is when the Ice Age took place. This time is fairly important because this was when the first fossils of homo sapiens date back, 200000 years ago. The homo sapiens were the start of us, and without this era, there would be no us, the humans. The other important period was the Jurassic Period. This period stood out to me because this was when the dinosaurs dominated the food chain and they were the most abundant and diverse. This period really made the dinosaurs so popular at this time. Finally, the Cretaceous Period was a very important time for humans. This was when the meteor hit Earth, wiping out much of the dinosaur population, allowing humans to take over. Without this meteor that struck Earth, we would not be here. The dinosaurs would still be on top of the food chain, and we would not be able to survive. The Earth history, when on a scale, is extremely massive. The formation of Earth took much longer than I expected it to. I learned that the Earth took a very long time for it to become like what it is today. What surprised me about the scale was the fact that humans, and their advancements, are on the last hour of the cosmic year. Even though we have not been on Earth for very long, we have impacted the Earth significantly, wether it is good or bad. We have created more technology and more efficient ways of surviving on Earth. However in doing so, we have caused some major problems that will harm us in the future. I wonder what will happen if we decide to continue what we are doing? How much harm will global warming cause us if we don't change our ways?
