The exosphere is the outermost layer of Earth's atmosphere. It extends from the top of the thermosphere to the edge of space. The exosphere is composed of extremely low-density gases, such as hydrogen and helium, as well as some heavier molecules like oxygen and nitrogen. The particles in the exosphere are so far apart from each other that they can travel long distances without colliding with one another.
To understand the exosphere better, here are some key points to focus on:
Additionally, it's important to familiarize yourself with the layers of Earth's atmosphere and their characteristics, as well as the impact of the exosphere on space weather and satellite communication.
Understanding the exosphere is crucial in comprehending Earth's relationship with the wider universe and the effects of solar activity on our planet.
