Planet Zentali is an Earth-sized planet with an atmosphere of silicon dioxide, oxygen, argon, and other various gases.
The life is sulfur and silicon based, and most carnivores have near Infared vision due to the increased air pressure. There are lakes and ponds of colorless tetrasilane that evaporate and create a precipitation cycle. However, not many big bodies of tetrasilane get built up as it is flammable.
Since it is close to its sun, the temperatures get very hot; up to 175 degrees Fahrenheit, or 80 degrees Celsius.
Photosynthesis is very similar to Earth's, but with sulfur in the process instead of carbon.
The crust is a multitude of different minerals, most of which is aluminum, iron, germanium, silicon, and sulfur.
