During the most recent Ice Age, which ended around 11,700 years ago, the two main changes on Earth were the expansion of glaciers and ice sheets, covering large portions of continents, and the drop in sea levels as water became trapped in ice. These changes had significant impacts on the environment and led to the migration and adaptation of many species, including early humans.

During the most recent ice age, which occurred around 20,000 years ago, large parts of Earth were covered in ice sheets and glaciers. Sea levels were much lower due to the amount of water locked up in ice, and there were changes in climate patterns and ecosystems. Human populations spread to different regions as they adapted to the changing environment.
The earth science that examines the physical and biological changes that have occurred in earth's past is called paleontology. Paleontologists study fossils and other evidence to understand how life forms and the Earth itself have evolved over time.
No, the Earth's eras are not the same length. They vary in duration. The eras are typically distinguished by significant geological and paleontological changes that have occurred during each period of time.
The area of Earth science that examines the physical and biological changes that have occurred in Earth's past is called paleontology. Paleontology focuses on studying fossils and ancient life forms to understand the history of life on Earth.
