What was the first organism that released oxygen into the earths atmosphere?
The first organisms that released oxygen into Earth's atmosphere were cyanobacteria, also known as blue-green algae. These microorganisms performed photosynthesis, using sunlight to convert carbon dioxide and water into glucose and oxygen. This process began approximately 2.4 billion years ago during the Great Oxygenation Event, fundamentally changing the planet's atmosphere and paving the way for the evolution of aerobic life forms.

How was earths early atmosphere first changed?
Earth's early atmosphere was first changed through volcanic activity, which released gases such as water vapor, carbon dioxide, and nitrogen. This led to the formation of oceans and the gradual accumulation of oxygen through photosynthesis by early organisms like cyanobacteria. This oxygenation process transformed the atmosphere to one more similar to the one we have today.

The first layer of the earths atmosphere touching earths surf?
