The Antarctic is one of the last unspoiled areas on earth. Air gets trapped in packed snow fall, later gets very packed, sometimes slightly melted, but not enough for the air to get out. This process has gone on for millions of years. When scientists take ice core samples, it is for the air that is trapped, deep down, where it was trapped millions of years ago. They take these samples, into a laboratory, where they carefully extract the air samples. Then they will use a gas chromatograph, IR spectrum analyzer, or other instrumentation to determine the composition of the air sample. The depth of the ice core determines the age of the earth at the time, and with the many ice core samples taken, there are many to compare it to for which to make a better determination.

What prediction do scientists make about how the composition of earths atmosphere will change in the future?
Scientists predict that the composition of Earth's atmosphere will change in the future due to human activities such as burning fossil fuels, leading to an increase in greenhouse gases like carbon dioxide. This is expected to cause global warming and climate change, with potential negative impacts on the planet's ecosystems and weather patterns.
What is the primary (most abundant) gas in the Earths atmosphere?
The primary gas in Earth's atmosphere is nitrogen, accounting for about 78% of the total atmospheric composition.
Which group of organisms is most responsible for changing the compisition of earths early atmosphere?
Cyanobacteria are the group of organisms most responsible for changing the composition of Earth's early atmosphere. Through photosynthesis, they released oxygen into the atmosphere, fundamentally altering its composition and paving the way for aerobic organisms to evolve.
What can scientist use to study the changes in the earths atmosphere?
Scientists can use instruments like satellites, weather balloons, and ground-based stations to study changes in the Earth's atmosphere. These tools can measure parameters such as temperature, humidity, air pressure, and the concentrations of gases like carbon dioxide and methane. By analyzing data collected from these instruments, scientists can understand trends and patterns in atmospheric changes.
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.
Why is earths composition of earths atmosphere important?
The Chemical Composition of the Earth's atmosphere is important because it holds the Earth together.
How does the composition of Earths atmosphere different from the composition of the atmosphere of the gas giants planets?
The Gas Giants have a deep gas atmosphere and earth have a not so deep atmosphere
