Which would be least helpful to scientist trying to find evidence that earth is very old?
Examing contiental drift
What evidence of changes in earth's magnetic field is found in rocks?
Evidence of changes in Earth's magnetic field is found in rocks through the study of their magnetic minerals, which can record the direction and intensity of the magnetic field at the time of their formation. When volcanic or sedimentary rocks cool or are deposited, iron-bearing minerals align with the Earth's magnetic field, preserving a "fossil" record of its orientation. This phenomenon, known as paleomagnetism, allows scientists to detect shifts in the magnetic poles and changes in the field's strength over geological time. Analyzing these magnetic signatures helps reconstruct past continental movements and understand the dynamics of Earth's magnetic field.
What is a map hearing?
A "Mapp" hearing is a pre-trial hearing on whether or not to suppress a piece of evidence that is going to be introduced at trial. The evidence could be tangible evidence, such as an illegal substance, or intangible evidence, such as a confession.
What evidence supports that earth is neither shrinking nor growing in size?
Evidence supporting that Earth is neither shrinking nor growing includes the measurement of its mass and volume, which have remained relatively constant over geological time scales. Satellite measurements and geodetic techniques show that the planet's dimensions are stable, with only minor fluctuations due to tectonic activity. Additionally, the balance of incoming and outgoing matter, such as meteorite impacts and atmospheric escape, does not significantly alter Earth's overall size. These observations reinforce the understanding that Earth maintains a consistent size.
If evidence has been moved prior to photography what should you do?
If any evidence was moved by the first responders prior to your arrival, photograph it's present location and condition. Never have the officer place the item of evidence back where it was originally located.
What was the first evidence of the Bantu migration?
Linguistic Evidence
What does reconstruction evidence mean?
It refers to using the evidence available to 'reconstruct,' insofar as possible, what happened during the offense.
How can you prove prehistorical human migration?
Researchers use various archaeological and genetic evidence, such as artifacts and fossil remains, to reconstruct prehistorical human migration patterns. By studying tools, art, and DNA, scientists can track the movement of ancient populations and identify common ancestors or migration routes. Advances in technology and interdisciplinary research have shed light on the movement of early humans across different regions of the world.
Which evidence exists of a migration in ancient Africa?
Linguistic Evidence
What kinds of evidence do scientists use to study early migration?
Scientists use a variety of evidence to study early migration, including genetic analysis of modern and ancient populations, archaeological artifacts, isotopic analyses of human remains to trace diet and geographic origin, and studies of ancient pollen and plant remains to reconstruct past environments. By combining these different lines of evidence, scientists can piece together the story of how humans migrated and settled around the world.

How was fossil evidence used to reconstruct Pangea?
The intersection of a common fossil on two different landmasses' borders allowed scientists to reconstruct Pangaea.
What did scientist study in order to learn about early humans?
Scientists study fossils, artifacts, and genetic material to learn about early humans. By analyzing these sources of evidence, researchers can reconstruct the behavior, diet, migration patterns, and evolutionary history of our ancestors.
Why is it important to record the crime scene?
Recording the crime scene is crucial to preserve evidence before it is disturbed or altered. It helps investigators reconstruct the event, identify potential suspects, and build a strong case for prosecution. Detailed documentation also ensures transparency and accountability in the investigation process.
What evidence do archaeologists have to support their theory regarding the first people?
Archaeologists use a combination of artifacts, ancient DNA analysis, geological evidence, and carbon dating to reconstruct the history of the first people. These sources help to determine the timing and routes of human migration out of Africa and across different continents. Additionally, studying early human skeletal remains provides insights into the physical characteristics and lifestyles of these ancient populations.
Why are linguists unable to reconstruct languages that have no written record?
Linguists are unable to reconstruct languages that have no written record because written records provide important clues and evidence about a language's vocabulary, grammar, and pronunciation. Without written records, linguists have limited sources to work with, making it difficult to accurately reconstruct the details of a language that has no written record.
What evidence did you use to reconstruct Pangaea?
Scientists used several lines of evidence to reconstruct Pangaea, including the fit of the continents like puzzle pieces, matching rock formations and fossils across continents, similarities in the geology and mountain ranges of continents, and past climate patterns indicated by glacial deposits and coal beds. These pieces of evidence helped to support the theory of continental drift proposed by Alfred Wegener in the early 20th century.
