How do earths layers contribute to the planets physical characteristics?
The Earth's layers contribute to the planet's physical characteristics by the types of rocks these layers produce. The rock formation of the Earth's surface define the physical characteristics of the planet.
What two types of ages of rocks that geologists talk about?
Geologists talk about relative ages and absolute ages of rocks. Relative ages are determined by the order of rock layers, with younger layers on top and older layers at the bottom. Absolute ages are determined through radiometric dating methods to provide a specific age in years for a rock sample.
What are relative fossils?
Answer: The age of a rock compared to the ages of the rock layers.
Which law deals with the relative ages of layers of sedimentary rocks?
Time
What characteristics was first used to identify earths layers?
the berrics
What is correlative dating?
Correlative dating is a method used in geology to determine the relative ages of rock layers or formations in different locations by comparing their characteristics and determining their equivalence based on similarities. This technique relies on identifying similar patterns, fossils, or other features in different rock layers to establish a chronological sequence.
How are the sublayers of the mantle divided?
Based on the physical characteristics of those layers.
How can you use fossils and geological features to interpret the relative ages of rock layers?
you cant
What type of dating involves matching up layers of rocks from two?
The type of dating that involves matching up layers of rocks from two different locations is known as lithostratigraphic correlation or stratigraphic correlation. This method allows geologists to establish the relative ages of rock layers by comparing their characteristics and sequences. By correlating these layers, scientists can reconstruct geological histories and understand the temporal and spatial relationships of rock formations. This technique is essential in fields like paleontology and archaeology for dating and contextualizing findings.
By applying the law of superposition what dates can be determined?
By applying the law of superposition, the relative ages of sedimentary rocks can be determined. This allows geologists to arrange rock layers in chronological order, with the oldest layers at the bottom and the youngest layers at the top. Absolute dates (specific numerical ages) cannot be determined solely through the law of superposition.
Describe three characteristics of the Scandinavians during the high Middle Ages?
Three characteristics of the Scandinavians during the high Middle Ages was the rise of Christian monotheism, powerful rulers such as Charlemagne, and theologians including St. Augustine.
How have the characteristics that people have found useful in farm animals changed through the ages?
The characteristics have changed throughout the ages due to selective breeding. Farmers look for certain characteristics do do certain jobs.For example. A cheep was used for wool, milk, leather and meat but nowadays they are used for wool and meat.
