Scientists use ice core samples as a way to determine what kind was in the atmosphere at different times in history. They melt the ice core under a vacuum hood to retrieve any gases in the ice. They then take the water and run it through different instruments to determine what type of pollution, dust, ash, radiation, and metals were trapped in the ice. This helps determine what the weather was like at different points in time.
What else can I help you with?
How do tree rings and ice cores help scientist understand how Earth has changed over time?
Scientist drill into ice and remove ice cores for study. Scientist analynze air trapped in the ice to learn how the atmosphere has changed. Scientists can develop an accurate history of overall weather patterns over time.
How often do scientists say that recent cycles of advancing and retreating ice sheets occur?
The answer choices for this question are missing. However approximately 100,00 years is how often scientists say that the recent cycles of advancing and retreating ice sheets occurred.
Ice samples from glaciers provide evidence that today's atmosphere contains more carbon dioxide than ancient atmosphere on earth did.why id this increase in carbon dioxide a concern to scientists?
It is of no concern to scientists - its just data. However, it is a concern to the human beings who are also scientists since their environment is getting fouled up.
Do scientists use the measure of density to tell if something will float?
yes. for example; Ice is just frozen water, right? So why does ice float in water? When we find the mass of an ice cube and divide that by its volume, we come up with about .92. Ninety-two hundredths is less than one, so the density of ice is less then that of water. Ice floats because the ratio of its mass to volume is less than one.
What are some Catchy science fair project about melting ice?
One catchy science fair project about melting ice could be investigating the effects of different substances, such as salt, sugar, or sand, on the rate of ice melting. Another idea could be studying how the shape or size of ice cubes affects their melting time. Additionally, you could explore how environmental factors, like temperature or humidity, impact the melting rate of ice. These projects would allow for hands-on experimentation and the opportunity to analyze and interpret data.
What can scientist learn by studying these ice cores?
Scientists can learn about the Earth's past climate by studying ice cores, as they provide records of past temperatures, atmospheric composition, and precipitation. This information helps scientists understand natural climate variability and can be used to improve climate models and predict future climate trends. Additionally, ice cores can also contain information about ancient air pollutants, volcanic eruptions, and even the history of human influence on the environment.
What have scientists learned from studying ice cores?
Scientists studying ice cores have learned about past climate conditions, atmospheric composition, volcanic eruptions, and even ancient civilizations. By analyzing the layers of ice, researchers can reconstruct historical climate patterns and gain insights into Earth's past climate variability. Ice cores have provided valuable data for studying climate change and understanding the factors driving it.
How do scientists learn about the climate in Antarctica thousands of years ago?
Ice cores are useful for scientists who want to learn about the climate in Antarctica thousands of years ago.
What do scientist learn from ice core samples?
Scientists can learn about past climate conditions, atmospheric composition, and volcanic eruptions by studying ice core samples. The layers in ice cores provide a record of environmental changes, allowing researchers to track shifts in temperature and understand how the Earth's climate has evolved over time. Ice cores also contain air bubbles that trap ancient gases, giving insights into past atmospheric conditions.
How can ice cores tell us what the temperature was?
Ice cores contain trapped air bubbles with ancient atmospheric gases that can be analyzed to reconstruct past temperatures. Isotopic composition of oxygen and hydrogen in ice can also give clues about past temperature variations. By studying these factors in ice cores, scientists can reconstruct past climate conditions and temperatures.
How do tree rings and ice cores help scientist understand how Earth has changed over time?
Scientist drill into ice and remove ice cores for study. Scientist analynze air trapped in the ice to learn how the atmosphere has changed. Scientists can develop an accurate history of overall weather patterns over time.
Why is studying ice cores Important to geological history?
Studying ice cores is important to geological history because they provide a record of Earth's past climate and atmospheric conditions. By analyzing the gases, chemicals, and particles trapped in the ice, scientists can reconstruct past climates, track changes in temperature, and understand the impact of human activities on the environment. Ice cores also help in understanding the Earth's natural climate variability and can be used to predict future climate trends.
What way scientist can learn about the past is to study?
Scientists can learn about the past by studying various sources such as fossils, ice cores, sediment layers, and historical documents. By analyzing these sources, scientists can piece together information about events, climates, and life forms that existed in the past. These studies help provide insights into how the Earth and its inhabitants have changed over time.
Why do scientists study frozen water?
Scientists study frozen water, or ice, to understand its properties, behavior, and impact on the environment. Studying ice can provide insights into climate change, glacier movement, and ocean circulation. Additionally, ice cores can provide valuable information about past climates and atmospheric conditions.
How do scientists study ice cores?
Scientists study ice cores by extracting cylindrical samples of ice from glaciers or ice sheets. These ice cores contain trapped air bubbles, dust particles, and other materials that provide information about past climate conditions. By analyzing the layers in the ice cores, scientists can reconstruct historical climate data, such as temperature and atmospheric composition, dating back thousands of years. This research helps us understand how the Earth's climate has changed over time and improve predictions for the future.
Why do scientists study ice cores?
When ice freezes it can freeze gas and other material inside of it and some ice may have been there from thousands of years ago and scientists may want to find out how much carbon dioxide was in the atmosphere then etc.
Why do scientists save long tubes of ice?
Scientists save long tubes of ice, known as ice cores, because they contain information about past climate conditions, such as temperature, atmospheric composition, and precipitation. By analyzing the layers in ice cores, scientists can reconstruct past environmental changes and understand how the Earth's climate has evolved over time.
