Which layer is rich in oxygen?

Published in Atmosphere 1 min read

The layer that is rich in oxygen is the troposphere. The troposphere is the lowest layer of Earth's atmosphere, extending from the surface to about 7 to 15 kilometers (4 to 9 miles) in altitude. This is where we live and where most weather occurs. As we move higher up in each layer of the atmosphere, the gases thin out. This means that the troposphere has the highest concentration of oxygen compared to other layers.
