neptune is a gas giant. gas giants do not have volcanos.
The Victorian Era was in the early 1900's. The most used form of lighting during this era was gas lighting. Candles were still used at this time as well.
Unless changed during current times; CS was SOP for training men during the Vietnam War era. To include the gas chamber.
Companies could charge as much as they liked.
I G Farben produced Mustard Gas (bis(2-chloroethyl) sulfide) during WW 1. They went on to produce other poison gasses, such as Phosgene, and during WW 2 produced Nerve gasses such as Tabun, Sarin, and Soman.
Volcanoes did not produce oxygen in the Precambrian era. The composition of volcanic gases during this time period mainly consisted of carbon dioxide, water vapor, and sulfur gases, but minimal oxygen was present due to the lack of photosynthetic organisms producing it.
Volcanoes can produce lava, ash, and gas.
It is very empty and only single-celled organisms were present in the Precambrian era. No animals were living on land because of the poisonous gas in the air.
Oxygen was lacking from Earth's atmosphere during the Precambrian era. This period of Earth's history, which spans from about 4.6 billion years ago to around 541 million years ago, is characterized by low oxygen levels in the atmosphere due to lack of photosynthetic organisms producing oxygen.
the gasses were dissolved in the lava until the pressure was released near the surface.
Gas was lacking from Earth's early atmosphere in the early Precambrian era because the primitive atmosphere was composed mainly of hydrogen and helium, which were lost over time. The formation of the Earth's magnetic field and the development of the ozone layer prevented the atmosphere from being stripped away by solar winds, leading to the accumulation of gases like carbon dioxide and water vapor over billions of years.
The Precambrian time, which includes the majority of Earth's history, began approximately 4.6 billion years ago with the formation of the Earth. This time period encompasses about 88% of geologic time and is divided into the Hadean, Archean, and Proterozoic eons.
first era was the Precambrian
The gas giants have no volcanoes; they are composed entirely or almost entirely of gas, so there is nothing to erupt. However, it should be noted that some of the satellites of the gas giants do have volcanoes.
oxygen
All volcanoes are made of gas and magma.
Gas is what gives volcanoes most of their power. One of the reasons this happens is because the gas keeps expanding.
