The sequence of the eras of Earth's history from oldest to most recent is: Precambrian, Paleozoic, Mesozoic, and Cenozoic. The Precambrian era comprises the earliest stages of Earth's formation, followed by the Paleozoic era known for the rise of complex life forms. The Mesozoic era is characterized by the age of dinosaurs, and finally, the Cenozoic era represents the current era with the dominance of mammals.
During our current era, known as the Anthropocene, the Earth has been notably changed by human activity. This includes impacts like climate change due to greenhouse gas emissions, deforestation, biodiversity loss, pollution of air and water, and alteration of landscapes through urbanization and agriculture. These changes have significant and lasting consequences for the planet's ecosystems and the well-being of all living organisms.
Rhyolite has probably been around as long as Earth has, or about 4.6 billion years.
During the Cenozoic era, the Earth's continents continued to move to their current positions, leading to the formation of familiar landmasses. The climate transitioned from warm and tropical to cooler and more varied. Mammals became the dominant land animals, evolving and diversifying into the species we see today.
The current era is the Cenozoic. It began 65.5 million years ago. The previous era was the Mesozoic.
The beginning of Earth's current era is marked by a mass extinction.

The current era today is Cenozoic
Plants have been around on the Earth since the Cambrian part of the Palenzonic Era.

The current era is the Cenozoic Era.

The age of the Earth is measured in geologic time scales that are divided into eras, which are then further divided into periods, epochs, and ages. The current era we are in is the Cenozoic era, and within this era, we are in the Holocene epoch. These divisions help scientists study the Earth's history and understand how life has evolved over time.
