How do scientists learn about the levels of carbon at different times in the past?
Scientists can study past levels of carbon through techniques like ice core analysis and sediment core analysis. By analyzing trapped air bubbles in ice cores or carbon isotopes in sediment cores, researchers can determine historical levels of atmospheric carbon dioxide. These methods provide valuable insights into past climates and help us understand the impact of human activities on carbon levels.
Why have carbon dioxide levels in the earth fallen?
Carbon dioxide levels have not fallen. They have been gradually increasing for the past 250 years when man began burning fossil fuels and cutting down trees. Since 1980 CO2 levels have increased more rapidly than ever before.
How have temperatures and carbon dioxide varied in the past?
In the past, temperature and carbon dioxide levels have varied naturally due to factors such as volcanic activity, solar radiation, and the Earth's orbit. During periods of high carbon dioxide levels, temperatures tend to be warmer, and vice versa. This historical data is important for understanding the relationship between carbon dioxide and temperature, as well as predicting future climate trends.
What can scientist learn from earths past from fossils?
Scientists can learn about the evolution of different species, past environments, and the impact of geological events on life by studying fossils. Fossils provide valuable information about extinct plants and animals, their behavior, and their adaptations to changing conditions over time. Additionally, studying fossils can help scientists understand the patterns of extinction and diversification throughout Earth's history.
Is the percentage of carbon dioxide 0.06?
No, the current atmospheric concentration of carbon dioxide is approximately 0.041% (410 parts per million). A level of 0.06% would be significantly higher and is closer to historical levels during certain periods in Earth's past.

What do scientist study to learn about prehisory?
they learn to examine objects to learn about past people and culture
What can scientist learn about the past by studying fossils?
What kinds of things lived in the past.
Scientist who study artifact to learn about the past are called?
Archaeologists
Who is a scientist who examines artifact and objects to learn about the human past?
An archaeologist is a scientist who studies artifacts and objects to learn about human history and culture. They analyze ancient tools, structures, and other items to understand how past societies lived and interacted with their environment.
How do scientist learn about organisms in the past while studing a fossil?
because they are preserved in the rock formations
What is a scientist who studies clues to learn about people who lived long ago?
An archaeologist(the study of the past by studying artifacts)
How do social scientists work together to learn about the past?
social scientist work together by sharing clues, reports,and etc....
What does the word archaelogoist mean?
A scientist who examines bones, tools structures, and other objects to learn about past peoples and cultures.
How can scientist today learn about earth's past climate?
By looking at the air trapped inside bubbles, fossils, and tree rings.
What are the levels of carbon dioxide from past to present?
During the past 500,000 years, levels of carbon dioxide in the atmosphere never rose above 300 ppm (parts per million) or 0.03%. Since the Industrial Revolution, 200 years ago, when we began burning coal, levels have risen to their present (2013) levels of 400 ppm (parts per million) or 0.04%.
How can scientists see what happened in the past by using the layers of earth?
It's because of the different levels of carbon or something.
