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.

What can layers of Arctic Ice tell us about atmospheric changes?
The different layers of ice can tell us a lot of things. They can tell us how much snow accumulated in a particular season, similar to looking at tree rings. They also contain atmospheric gases trapped in the ice. This gives an indication of the composition of the atmosphere at the time, since the ice can be dated.
What does this tell us about the temperature at the martian poles?
The temperature at the Martian poles is extremely low, often dropping to around -125 degrees Celsius (-195 degrees Fahrenheit) during winter. This frigid environment is influenced by the planet's thin atmosphere and the presence of polar ice caps made primarily of water and carbon dioxide ice. Seasonal changes lead to fluctuations in temperature, contributing to the sublimation and deposition of these polar ice caps. Overall, the conditions at the poles illustrate the harsh climate of Mars and its significant temperature variations.
What can a star's spectrum tell us?
scientists can tell the stars composition and temperature from its spectrum. Hope tht helps :]
How do you know that the earth is getting warmer?
Satellites and weather stations take measurements all the time from all over the world. They tell us the temperature is rising.The fact that glaciers, ice caps and sea ice is melting is an indication.The fact that sea levels are rising is an indication.
How do scientists know the atmospheric levels of carbon dioxide that exist on earth hundreds or thousands of years ago?
They measure it from bubbles of gas trapped in Antarctic ice.Primarily by the scientific examination of Ice Core Samples taken thousands of feet Deep from thousands of Sites around Earth.It is an interesting process really. When ice freezes, it has very tiny atmospheric gas bubbles trapped in the ice. There is a place in the Antarctic, known as Lake Vostok, that we are able to take and drill down very deep and get very clean samples of what the air was like. These samples will tell us what the atmosphere was like at a given time, by how far down the sample was taken from. From these cores, we are able to get actual gas bubbles of atmosphere from up to 650,000 years ago.
How can ice cores be used to tell us how earths climate has changed over time?
Ice cores contain valuable information such as air bubbles and isotopic composition that can be used to reconstruct past climate conditions like temperature and atmospheric composition. By analyzing the layers of ice cores, scientists can track changes in these parameters over time and gain insights into how Earth's climate has evolved.
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.
What can bubble of atmosphere trapped in glacial ice tell us?
they can tell you when the ice froze :$
How do the core samples from ice tells us about the atmosphere?
Core samples from ice contain information about past atmospheric composition and climate conditions. By analyzing gas bubbles trapped in ice cores, scientists can determine levels of greenhouse gases like carbon dioxide and methane over time. Isotopic analysis of the ice can also provide insights into temperature fluctuations and changes in atmospheric circulation patterns.
What is the equivalent temperature on the celsius scale?
You need to tell us what temperature you want to convert - and from which temperature scale !
What does temperature tell us about atoms?
Temperature is related to the average energy per particle.
What does the cricket's sound tell us about the temperature?
it is wanting rain
How do tree rings and ice core help scientist understand how earth has changed overtime?
Tree rings and ice cores provide valuable information about past climate conditions. Tree rings can show annual growth patterns which are influenced by factors like temperature and precipitation, while ice cores contain air bubbles and particles that can reveal past atmospheric composition and temperatures. By analyzing these samples, scientists can reconstruct past environmental conditions and study how the Earth's climate has changed over time.

What does the color of the sun tell us?
It shows the temperature of the sun. How hot of how cold.
Why do scientits go to Antarctica?
They go there because they want to get the ice cores and and see what temperature it was in antarctica. They are focusing on biology, geology, ice and climate changes. They are very facinated of Antarctica but people want to stop them fromdoing experiments. But most people think that it is better for all of us because they can check the global warming.
What is Jackie Robinson's favorite ice cream flavor?
His biography doesn’t tell us that information.
