The scale of human impact on Earth The Anthropocene is sometimes used to simply describe the time during which humans have had a substantial impact on our planet. Whether or not we are in a new geological age, we are part of a complex, global system and the evidence of our impact on it has become clear.

democracy. a government run by the people, in which the citizens make their own laws. A Greek word meaning “power of the people”. assembly. The basic lawmaking body in a democracy, made up of a grou of citizens.

The word human comes from the Latin word “humus,” meaning earth or ground.

recent

-cede-, root. -cede- comes from Latin, where it has the meaning “go away from; ” This meaning is found in such words as: accede, antecedent, cede, concede, precede, precedent, recede, secede.

Holocene

Scientists have just assigned three new ages to the Holocene, which is the current epoch in which we live. They’re calling this most recent age the Meghalayan, which began 4,200 years ago during a worldwide megadrought. The Holocene commenced 11,700 years ago after the end of the last ice age.

The Information Age began around the 1970s and is still going on today. It is also known as the Computer Age, Digital Age, or New Media Age. This era brought about a time period in which people could access information and knowledge easily.

Geological era The next-larger division of geologic time is the eon. The Phanerozoic Eon, for example, is subdivided into eras.

Paleoproterozoic

Quaternary Period

The Precambrian, Paleozoic, Mesozoic, and Cenozoic Eras The Geologic Time Scale is the history of the Earth broken down into four spans of time marked by various events, such as the emergence of certain species, their evolution, and their extinction, that help distinguish one era from another.

The College Board has broken down the History of the World into six distinct periods (FOUNDATIONS, CLASSICAL, POST-CLASSICAL, EARLY-MODERN, MODERN, CONTEMPORARY.

Terminology. The primary and largest catalogued divisions of time are periods called eons. The first eon was the Hadean, starting with the formation of the Earth and lasting over 600 million years until the Archean eon, which is when the Earth had cooled enough for continents and the earliest known life to emerge.

Mesopotamia

The Prehistoric Period—or when there was human life before records documented human activity—roughly dates from 2.5 million years ago to 1,200 B.C. It is generally categorized in three archaeological periods: the Stone Age, Bronze Age and Iron Age.

The three-age system is the periodization of human pre-history (with some overlap into the historical periods in a few regions) into three time-periods: the Stone Age, the Bronze Age, and the Iron Age; although the concept may also refer to other tripartite divisions of historic time-periods.

10,000 years ago (8,000 BC): The Quaternary extinction event, which has been ongoing since the mid-Pleistocene, concludes.

The Ice Age just barely edges out the Stone Age for the first development, since the beginning of long-term cooling and glaciation preceded the first…

If early humans controlled it, how did they start a fire? We do not have firm answers, but they may have used pieces of flint stones banged together to created sparks. They may have rubbed two sticks together generating enough heat to start a blaze. Fire provided warmth and light and kept wild animals away at night.

Homo habilis

The last of the non-avian dinosaurs died out over 63 million years before the Pleistocene, the time during which the regular stars of the Ice Age films (mammoths, giant sloths, and sabercats) lived.

The ice age happened after the dinosaurs. The dinosaurs died out prior to the Pleistocene age, which was the last of five ice ages that spanned…

The first has dinosaurs, alongside Adam and Eve, living in harmony. The ferociously fanged T. rex is likely to be a vegetarian.
