in the beginning of earth it was extremely hot with very little oxygen

What word do we apply to the concept that the processes that are at work on earth today are the same processes that shaped the early history of earth?
Geology
What are three ways the Earth is different today from when it was first formed?
The Earth's atmosphere has changed over time, with early Earth lacking oxygen while today it has a higher oxygen content. The planet's land mass has also shifted due to plate tectonics, leading to the formation of continents. Additionally, the Earth's surface has been shaped by erosion and weathering processes over millions of years.
How were conditions on the early Earth of more than 3 billion years ago different from those on today's Earth?
The early Earth had higher temperatures, little to no oxygen in the atmosphere, higher concentrations of carbon dioxide, and a more violent geological activity due to frequent volcanic eruptions and impact events. Additionally, the early Earth lacked the protective ozone layer present today, which allowed for intense ultraviolet radiation from the sun to reach the surface. Conditions were more conducive to the development of simple life forms in these harsher environments.
How is the earth today different from back them?
There aren't dinosaurs anymore.
What was earth like 650000 years ago?
650,000 years ago, Earth was in the midst of an ice age known as the Early Pleistocene. The climate was generally cooler than today, with a series of glacial and interglacial periods shaping the landscape. Early humans, such as Homo erectus, were present, and the environment would have looked significantly different from what we see today.
How did old earth look like?
Old Earth, also known as "Paleo-Earth," looked very different from the Earth we know today. It had a vastly different climate, with different land formations, vegetation, and animal species. Continents were arranged differently, and there were different geological and environmental conditions.
How many lanugages are spoken on earth today?
There are approximately 7,000 languages spoken on Earth today. This number can vary slightly based on different classification methods and dialect distinctions.
When did scientists think the moon was created?
There's a few different theories on this, but today, most astronomers feel that very early in earth's history - when it was still essentially a ball of molten rock - Earth was impacted by another huge object, perhaps half the size of earth. This blasted out a huge chunk that fell into orbit around the earth, and eventually became the moon.
How did the primitive atmosphere differ from the atmosphere today?
As opposed to today's atmosphere, the Earth's early atmosphere would have been quite impossible for human life to thrive in. Today the atmosphere consists primarily of Nitrogen, Oxygen, and Carbon Dioxide, but early Earth's first atmosphere was probably made of Hydrogen and Helium.
