1.) The early Earth was very different from our Earth today. ... These gases created a new type of atmosphere for Earth. The volcanic eruptions spewed gases such as nitrogen, carbon dioxide, hydrogen, and water vapor into the atmosphere—but no free oxygen. Without oxygen, there was still very little that could live on Earth.
2.) All of the environments on Earth change over time. Some changes are caused by the slow movement of the continents (plate tectonics) and take millions of years. Other changes are caused by variations in Earth's climate and take thousands of years.
