What can bubble of atmosphere trapped in the glacial ice tell us?
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.
Does composition of the atmosphere change with elevation?
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.
How do the changes in atmosphere composition throughout earths history illus trade the Gaia hypothesis?
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.
What predictions do scientists make about how the composition of Earths atmosphere will change in the future?
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.
How does the composition gases changes as you travel in earths atmosphere?
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.
How can scientists determine changes in the atmosphere?
Montoring weather
What changed the composition of the ancient atmosphere on Earth?
When plants and animals evolved, this made changes in the atmosphere on Earth

What methods do scientists use to find physical changes?
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.
What do scientists learn about changes that occurred in earths atmosphere a long time ago by studing what?
mold fossils
What do scientists believe explains the increased density of material deeper into the mantle?
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.

Why does the color of sunsets vary day to day?
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.

Why do scientists think there are s few redwood species alive today?
Scientists believe that changes in the Earth's climate cause extinction of trees;P
