Bubble of atmosphere trapped in glacial ice can provide valuable information about past atmospheric composition, temperature, and climate conditions. By analyzing the composition of gases in these bubbles, scientists can reconstruct the Earth's climate history and understand the levels of greenhouse gases in the atmosphere over time. This data helps in studying past climate changes and projecting future climate scenarios.
The atmosphere gos through many cycles and changes. The significant gases in our atmosphere have not changed substantially in the past several centuries. The primary gas is still Nitrogen, then Oxygen.
The changes in atmosphere composition throughout Earth's history, such as an increase in oxygen levels due to photosynthesis by early life forms, can be seen as evidence supporting the Gaia hypothesis. This hypothesis suggests that Earth's biosphere interacts with the atmosphere, oceans, and geology to maintain conditions conducive to life. The evolution of life on Earth has influenced the composition of the atmosphere, creating a self-regulating system that promotes the habitability of the planet.
Scientists predict that Earth's atmosphere will continue to experience an increase in greenhouse gases such as carbon dioxide, methane, and nitrous oxide, leading to further global warming and climate change. This is mainly due to human activities such as burning fossil fuels and deforestation. Efforts to reduce greenhouse gas emissions are crucial to mitigate these changes and their impacts on the planet.
As you travel higher in Earth's atmosphere, the composition of gases changes in terms of their concentration. Oxygen, nitrogen, and argon are the most abundant gases in the lower atmosphere, while the percentage of oxygen decreases and other gases like helium and hydrogen become more prevalent in the upper atmosphere. The overall pressure also decreases with altitude, causing the air to become less dense.

Scientists use a variety of methods, such as microscopy, spectroscopy, chromatography, and mass spectrometry, to identify physical changes in materials. These techniques help scientists observe changes in the size, shape, structure, composition, or properties of a substance, allowing them to understand how physical changes occur at a molecular level.

Scientists believe that the increased density of material deeper into the mantle is primarily due to the increase in pressure as you go deeper into the Earth's interior. The weight of the overlying rock layers compresses the material below, causing it to become more tightly packed and denser. Additionally, changes in mineral composition and temperature can also contribute to the increased density.

Because the composition of the atmosphere changes from day to day (specifically, the composition of particulates). These are what scatter sunlight in ways that can make sunsets colorful.
