Did earths original atmosphere contain methane and ammonia?
Yes, Earth's original atmosphere is believed to have contained methane, ammonia, water vapor, and other gases. This atmosphere was formed from gases released during volcanic activity. Over time, the atmosphere changed due to the presence of early life forms that produced oxygen through photosynthesis.
What gases where present in early earths atmosphere?
The early Earth's atmosphere consisted mainly of carbon dioxide, water vapor, nitrogen, and small amounts of methane and ammonia. Over time, as photosynthetic organisms evolved and produced oxygen, the atmosphere gradually transitioned to contain more oxygen and less carbon dioxide.
Why do scientist think the the amount of oxygen in the earth's atmosphere has increased?
Scientists believe that the amount of oxygen in Earth's atmosphere has increased over time due to the evolution of photosynthetic organisms, such as plants and cyanobacteria. These organisms release oxygen as a byproduct of photosynthesis, leading to an accumulation of oxygen in the atmosphere.
Do rainforests contain over half of all plant and animal species in the world?
Yes, rainforests are estimated to contain over half of the world's plant and animal species. These diverse ecosystems provide a wide range of habitats and niches that support an abundance of biodiversity. However, the exact number of species present in rainforests is difficult to quantify due to their vastness and complexity.
Why does earths atmosphere today contain more oxygen then the early earth?
The increase in oxygen in Earth's atmosphere is mainly due to the evolution of photosynthetic organisms like cyanobacteria and plants, which produce oxygen as a byproduct. Over time, these organisms gradually increased oxygen levels through the process of photosynthesis. This led to the rise of oxygen in the atmosphere from less than 1% to the current level of around 21%.

Did the earth's atmosphere always stayed the same?
no over time the atmosphere has changed cause if scientists look at the ice in Antarctica or the dirt in the ground then they always see the different colors cause they rep resent the different chemicals in the atmosphere i think
Does carlite plaster contain hydroscopic salts?
Yes, carlite plaster can contain hygroscopic salts such as sodium chloride or potassium sulfate. These salts can cause the plaster to absorb moisture from the atmosphere, leading to potential issues with dampness and degradation over time.
How does air masses that form over the land and ocean affect weather in the US?
i think that because the climates change from the atmosphere ;* <3 .
