The Gasses trapped in the air bubbles of the ice in the different levels can tell them what the atmosphere was like when the ice was formed, each layer of ice represents an different year or group of years, it has been there a very long time and provides a timeline of the earths climate changes to help predict what we are going to see in the future. It takes a lot of samples to get a complete picture. Sometimes there wont be a good sample in a particular core for a given time period so multiple cores are needed.

What are facts scientists have learned about earth's climate from core samples?
Scientists have learned about past climate conditions by studying ice core samples, including temperature changes, carbon dioxide levels, and atmospheric composition. They can also study the frequency and impact of natural events like volcanic eruptions and shifts in ocean currents by analyzing core samples. Overall, ice core data provides valuable insights into Earth's climate history and helps inform our understanding of future climate change.
What is one of the indications that the earth's climate has varied over time?
One indication of Earth's varying climate over time is the presence of ice core samples that show fluctuations in temperature and atmospheric composition. By analyzing the layers of ice cores, scientists can determine past climate conditions.
How do core samples help geologists?
Core samples help geologists by providing a detailed record of the Earth's subsurface, allowing them to study the composition, structure, and history of the rocks. By analyzing core samples, geologists can make interpretations about the past environments, climate changes, geological deformations, and even identify potential resources such as oil and gas deposits. Core samples also help in understanding the geological history of an area and its potential for natural hazards.
DNA fingerprinting is used to identify individuals by?
analyzing unique patterns in their DNA, such as short tandem repeats (STRs). By comparing these patterns between samples, scientists can determine the likelihood of a match, which is useful in forensic investigations, paternity testing, and identifying genetic diseases.
How have scientists used radioactive dating to show that earth is about 4.6 billion years old?
Scientists have used radioactive dating by measuring the decay of radioactive isotopes in rocks to determine their age. By analyzing the ratios of parent and daughter isotopes in samples, scientists can calculate the age of the rocks. This method has shown that the Earth is approximately 4.6 billion years old.
Scientists study small pockets of air trapped deep within frozen glaciers. What are scientists trying to understand about the climate of Earth by analyzing these ice samples?
By analyzing ice core samples, scientists can determine past levels of greenhouse gases, temperature changes, and atmospheric conditions. This helps to understand how the Earth's climate has changed over time and can provide valuable insights into current and future climate trends.

How is uranium found?
Analyzing samples of soils and waters, examinations of minerals, radiometric measurements in territory (also air surveillance).
Where do scientists get rock samples to discover earth's interior?
They recover rock samples from volcanic eruptions.
How do scientists identify unknown materials?
Scientists use a variety of techniques such as spectroscopy, chromatography, and microscopy to identify unknown materials. These methods involve analyzing the physical and chemical properties of the material to match them with known substances in databases or through comparison with reference samples. By comparing the data obtained from different techniques, scientists can determine the composition and characteristics of the unknown material.
How did the scientists verify the remains of the romanovs to be authentic?
Scientists took DNA samples from the remains of the Romanov family and compared them to DNA samples from known living relatives to know they were authentic.

Why do you need to collect water sample?
Collecting water samples is essential for monitoring water quality and identifying potential contaminants. It helps ensure the safety of drinking water, assess the health of aquatic ecosystems, and detect pollution sources. By analyzing water samples, scientists and environmental regulators can make informed decisions to protect public health and the environment.

What are the core top samples in marine geology?
The core top samples in marine geology are sediment samples collected from the top layer of the ocean floor. These samples are essential for studying past environmental conditions, including sea level changes, climate variations, and sedimentation rates. Analyzing core top samples can provide valuable insights into the history and dynamics of marine environments.
How do core samples help scientists learn about earth's history?
Core samples provide a snapshot of past environmental conditions by preserving layers of sediment or rock over time. Scientists can analyze these samples to understand past climates, ocean conditions, and even the presence of certain organisms, helping to reconstruct Earth's history and track changes over time.
