- Yes I am, First i will discuss the Hadean Era. Hadean is a geologic eon of Earth history preceding the Archean. On Earth, the Hadean began with the planet's formation about 4.54 billion years ago. The Hadean ended, as defined by the International Commission on Stratigraphy, 4 billion years ago. The Cenozoic is Earth's current geological era, representing the last 66 million years of Earth's history. It is characterized by the dominance of mammals, birds and flowering plants, a cooling and drying climate, and the current configuration of continents.
- Do you have knowledge about the transition of Earth's History based on the geological timescale?
- During the Archean Era, methane droplets in the air shrouded the young Earth in a global haze. There was no oxygen gas on Earth. Oxygen was only in compounds such as water. Complex chemical reactions in the young oceans transformed carbon-containing molecules into simple, living cells that did not need oxygen to live.
- And how about the Archean Era?
- The Proterozoic is a geological eon spanning the time interval from 2500 to 538.8 million years ago. It is the most recent part of the Precambrian supereon. The Paleozoic Era is the earliest of three geologic eras of the Phanerozoic Eon. The name Paleozoic was coined by the British geologist Adam Sedgwick in 1838 by combining the Greek words palaiós and zōḗ, life, meaning ancient life
- So, What is the Proterozoic Era?
- Did you know that the Paleozoic Era is the earliest of three geologic eras of the Phanerozoic Eon. The name Paleozoic was coined by the British geologist Adam Sedgwick in 1838 by combining the Greek words palaiós and zōḗ, life, meaning ancient life
- The Mesozoic Era, also called the Age of Reptiles and the Age of Conifers, is the second-to-last era of Earth's geological history, lasting from about 252 to 66 million years ago and comprising the Triassic, Jurassic and Cretaceous Periods.
- WOW! So, what is the Mesozoic Era?
- Cenozoic, The Cenozoic is Earth's current geological era, representing the last 66 million years of Earth's history. It is characterized by the dominance of mammals, birds and flowering plants, a cooling and drying climate, and the current configuration of continents.
- It’s so amazing! So, what is the next era you will discuss?
