Earth’s atmosphere not only provides the right mix of breathable air for animals and plants, but it – combined with an oxygen-rich ozone layer and the planet’s electromagnetic field – also acts as a force field against solar radiation and deadly space debris. The solar system’s other planets are typically too hot or too cold to support liquid water, but Earth is just right. Oceans cover nearly 70 percent of the planet’s surface and are a source of the water vapor responsible for our weather.
