What is The idea that the oldest rock will always be at the bottom layer of a series of rock layers called?
The idea that the oldest rock will always be at the bottom layer of a series of rock layers is known as the Law of Superposition. This geological principle states that in an undeformed sequence of sedimentary rocks, younger layers are deposited on top of older layers. It helps geologists determine the relative ages of rock formations and the fossils contained within them.
Series of layers in the ground?
The series of layers in the ground, known as soil horizons, typically consist of distinct levels: the top layer (O horizon) is rich in organic matter, followed by the A horizon (topsoil), which contains minerals and nutrients. Below that is the B horizon (subsoil), where minerals leach from the upper layers and accumulate. Finally, the C horizon consists of weathered rock and parent material, while the bedrock lies beneath these layers. Together, these layers contribute to soil health and ecosystem dynamics.
How do you determine the correct age of lava flow?
The correct age of a lava flow can be determined using radiometric dating methods, such as potassium-argon (K-Ar) or uranium-series dating, which measure the decay of radioactive isotopes in the rocks. Additionally, relative dating techniques, such as examining the stratigraphy of surrounding layers or the presence of fossils, can provide context for the flow's age. Radiocarbon dating may also be used for organic materials found within or beneath the lava flow. Collectively, these methods help establish a more accurate timeline of volcanic activity.
How can you determine the relative age of a rock layer by looking at a cross section?
In the cross section, examine the different layers. The layer at the very bottom will be the oldest, and the one above would be slightly newer, and the one above that even newer, and so on, until the most recent rock layer is found at the top. Therefore, the layer you study will depend on those features. If you know the age of one layer, you will know the relative age of another.
Where would the youngest rocks be found in an undisturbed layer of rocks?
In an undisturbed layer of rocks, the youngest rocks would be found at the top of the sequence. This is due to the principle of superposition, which states that in a series of sedimentary rock layers, older layers are deposited first and are subsequently covered by newer layers. Therefore, as you move upward through the layers, you encounter progressively younger rocks.
How the law of superposition helps scientist determine relative age?
Younger layers are deposited on top of older layers, whether the layer is sedimentary or volcanic. Occasionally faults may result in overthrusts, where a series of older layers may be pushed over the top of younger layers. But this is rare. In general, the older layers will be the lower layers.

What is the difference between absolute and relative memory address?
what is the difference between relative and absolute location? It could be the relationship that lets absolute memory relate to anything whiles relative memory is specific. When you remember something and its absolute then it means you can remember by any means so you have trained the brain to remember it by any means while relative memory is related by place or dimension. There is also such a thing as partial memory!
What is the difference between absolute frequency and relative frequency?
absolute frequency is a term decribing the total number of trials you did. a relative frequency is the number of measurements in an interval of a frequency distribution. or the ratio of the number of times an event occurs in a series of trials of a chance experiment to the number of trials of the experiment performed. so the difference is one is the total trials, and the other...well it depends on which definition you picked...

Absolute Boyfriend is a six volume series.
What is absolute convergence for an alternating series?
Absolute convergence for an alternating series refers to the situation where the series formed by taking the absolute values of its terms converges. Specifically, if an alternating series takes the form ( \sum (-1)^n a_n ), where ( a_n ) are positive terms, it is said to be absolutely convergent if the series ( \sum a_n ) converges. Absolute convergence implies convergence of the original alternating series; hence, if an alternating series is absolutely convergent, it is also convergent in the regular sense.

What are extremes in math?
