Answer:
Use the Sorting Tool activity to find another event in Earth’s history. Name the event and the period or eon in which the event occurred.
-541 million years ago, the Phanerozoic aeon began (or, 0.541 billion years ago). Consequently, the Phanerozoic aeon only accounts for 12% of Earth's history. Instead, the three Precambrian aeons represent the majority of Earth's history.
-The most recent period in Earth's history when human activity began to have a significant impact on the planet's climate and ecosystems is referred to as the Anthropocene Epoch. This term refers to an unofficial unit of geologic time.
-Plate tectonics moves the continents, mountains, and ocean floor, while unidentified mechanisms change the climate. Earth has experienced such continual upheaval since its creation some 4.5 billion years ago. Heat and gravity have impacted the evolution of the planet since the beginning.
-The geologic time scale separates the history of the earth into periods depending on the types of life that have existed there since the planet's formation. We refer to these divisions as geochronologic units (geo: rock, chronology: time).
