What else can I help you with?
What do scientists learn about changes that occurred in earths atmosphere a long time ago by studing what?
mold fossils
Can we see what elements are on different planets?
Yes, scientists use telescopes and space probes to analyze the composition of different planets. By studying the light that reaches us from these planets, scientists can determine the elements present in their atmosphere and surface materials.
How do scientists predict snow storms?
They use satellites, computer models, and observations from the atmosphere to determine what the weather is going to be.
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 do scientists think Europe has?
an atmosphere an atmosphere
How can scientists determine if oxygen existed in earth Archean atmosphere by?
Scientists can determine if oxygen existed in the Earth's Archean atmosphere by studying ancient rocks and minerals for chemical signatures that are indicative of oxygen presence. They look for isotopic ratios of elements like sulfur and carbon to infer the levels of oxygen in the atmosphere during that time. Additionally, biomarkers and fossils from that period can provide indirect evidence of oxygen-producing organisms.
Do scientists use atmosphere to determine or predict weather?
yes but only some times mostly they go out to space and then use it so it will determined better
How can scientists use fossils to determine environmental change?
fossils are used to determine the history of changes in environment and organisms because to see how they lived long ago on the environment and things like that
How do scientists determine where one layer ends and the next one begins?
Scientists determine where one layer ends and the next one begins by examining changes in sediment type, color, grain size, or fossil content. These changes often represent different time periods or environmental conditions that help scientists distinguish between layers. Additionally, techniques like radiometric dating can provide precise age estimates for different layers.
Why are scientists begin to worry about the levels of CFC in the atmosphere?
Scientists have began to worry about CFC's. They are going up in atmosphere and destroying ozone.
What kind of spectrum is used to determine the composition of a planet's atmosphere?
An absorption spectrum is typically used to determine the composition of a planet's atmosphere. This type of spectrum shows specific wavelengths of light that are absorbed by different gases in the atmosphere, allowing scientists to identify the presence of specific elements or compounds.
Which scientists helped to determine the shape of DNA?
The scientists who helped determine the shape of DNA were James Watson and Francis Crick.
