As the image shows, the layers 18-16 (starting from the bottom) are categorized as the vishu basement rocks, which are the oldest. Following are the Supergroup Rocks which include the layers from 15-12 aging up to 740 million years. All these layers are considered the Precambian era. The last group is the Paleozoic Rocks that include the remaining layers 11-1.…

Pleistocene: The most recent epoch of the late Cenozoic ice age, beginning about 1.8 million years ago and marked by as many as 20 glaciations and interglaciations of which the current warm phase, the Holocene epoch, has witnessed the rise of human civilization.…
Pleistocene Epoch of the Cenozoic Era|Many species of Pleistocene conifers, mosses, flowering plants, insects, mollusks, birds, mammals, and others survive to this day. This period was also known for many large mammals such as mammoths and their cousins the mastodons[->0], long horned bison, saber-toothed cats, giant ground sloths, and many other large mammals including humans.|2.6 million to 11,700 years ago|…

It is what the geologists developed as a model of the history life of Earth. Eons are the largest subdivision of geologic time. Eons are broken down into smaller units called Era. Today we are living in the Phanerozoic Eon and the Cenozoic Era.…

The history of the Earth is categorized into four different geological time eras beginning with, the Precambrian Time (4.6 billion-544 million years ago), the Paleozoic Era (544-248 million years ago), the Mesozoic Era (248-65 million years ago), and the Cenozoic Era (65 million years ago to the present). Eras are broken down further into smaller units called periods, which help scientists detect changes in Earth's history. Geologists's main sources of evidence for geological eras, and periods are the ages of rocks. There are several methods geologists't use to determine the age of rocks such as, relative age, the law of superposition, index fossils, relative dating, and radioactive dating. Through scientific reasoning and evidence this research…
Ever since the Homo sapiens sapiens species, of which all humans today are descendants of, appeared on earth, humans have been dealing with conflicts, and adapting their lifestyle to deal with those conflicts. It all started with the Paleolithic period and continued through the first civilizations. The Paleolithic period which was is better known as the Stone Age, carried on until about 14,000 years ago. While the first civilizations were the first representations of the civilizations that we live in today. Throughout the Paleolithic period and early civilizations, many factors of civilization have changed, but at the same time, many have stayed the same and were still used in the early civilizations as well as today.…
A: It is affected by temperature change, when the temperature rise it increase the rate of the anaerobic respiration, up to point. Soon the heat will start putting a lot of stress of the organism and then the rate of the anaerobic respiration will go down, more rising in temperature will eventually kill the organism.…
With the beginning of human history comes the Stone Age—comprised of the Paleolithic and Neolithic Eras. The start of tool-making marks the former; the start of agriculture marks the latter. The first forms of tools in the Paleolithic Era were quite basic and rough, made from materials like wood, bone, and stone. Tools such as choppers for cracking bone and scrapers for preparing animal hide were used, and were then designed upon by later hominoids, from which weapons like clubs, spears, and knives were developed. These rudimentary tools functioned as the people’s means of survival. As a hunter-gatherer society, one killed and foraged for food and shelter. Tools were the catalyst. Fire was also a catalyst. It assisted alongside tools in hunting…
The Paleolithic Era, also known as the “old stone age” was a time where humans foraged hunted wild animals or gathered edible portions of wild plants. Nothing was stored because people were always on the move. they couldn’t take the extra weight. The Neolithic Era or the “new stone age” refers to a period of time where humans began refining their tools for use on domesticated plants and animals. It was during this time that people began to store dry or wet things in pottery due to the surplus of food that had to be stored. The beginning of the Neolithic Era was the Transition to Agriculture. Neolithic peoples wanted to secure themselves a more stable lifestyle with a sure income of food. Women of this time began to nurture plants and men began…
The Neolithic Revolution changed gender roles because during the Hunting and Gathering days, men and women were equal in that they both shared the work. After the transition from Hunter Gathering days to the Neolithic Revolution, women stayed indoors more to take care of their children. This meant that they stayed home, instead of wandering around all the time searching for food. So, women were lower than men because they did not work. Men were higher because they control the amount of food they bring into the villages. Over the years the roles of both men and women have come full circle with the hunting and gathering days, to the Neolithic and back to equality today. I think the Neolithic Revolution was good.…
People in the axial age had the concerns of no modern technology. They were also more religiously based, and there were new thoughts on various aspects. In a different situation, such as a modern day city, people would be more based on the utility of the location of the city. Also, there would be more industrial buildings and structures than religious ones. The housing settlements would also be different, as now there are more strictly defined residential areas. The city centers before used to be a lot more clear and defined, while now it is mostly just a specific area usually made as a government building place.…
