Which of the following is the oldest rock layer?

Bedrock along the northeast coast of Hudson Bay, Canada, has the oldest rock on Earth. Canadian bedrock more than 4 billion years old may be the oldest known section of the Earth's early crust.Sep 25, 2008

Which of the following rock layers is the youngest layer?

The many horizontal layers of sedimentary rock illustrate the principle of original horizontality (Figure below). The youngest rock layers are at the top and the oldest are at the bottom, which is described by the law of superposition.Jul 16, 2012

Which of the following is the correct order for the rock layers from oldest to youngest?

The law of superposition states that rock strata (layers) farthest from the ground surface are the oldest (formed first) and rock strata (layers) closest to the ground surface are the youngest (formed most recently).

How will you describe the rock layer?

1. A horizontal layer of material, especially one of several parallel layers arranged one on top of another. 2. Geology A bed or layer of sedimentary rock that is visually distinguishable from adjacent beds or layers.

How old are the youngest rocks?

Researchers have dated the crystals to about 4.375 billion years ago, just 165 million years after the Earth formed. The zircons provide insight into what the early conditions on Earth were like.Dec 12, 2021

Which is the second-oldest sedimentary rock layer?

Which is the second-oldest sedimentary rock layer? The package of sediments C, D, E, and F is upside-down, as shown by the footprints and mud cracks, so C is the oldest one, and D is second-oldest.

Which is older fault or intrusion?

An intrusion is always younger than the rock layers around and beneath it. More clues come from the study of faults. A fault is a break in Earth's crust. A fault is always younger than the rock it cuts through.

Which feature in a rock layer is older than the rock layer?

First and foremost, they use the law of superposition to determine the relative ages of sedimentary rock layers. According to the law of superposition, in horizontal sedimentary rock layers the oldest is at the bottom. Each higher layer is younger than the layer below it.

Which was the first method used to determine ages of rock and fossils?

The age of rocks is determined by radiometric dating, which looks at the proportion of two different isotopes in a sample. Radioactive isotopes break down in a predictable amount of time, enabling geologists to determine the age of a sample using equipment like this thermal ionization mass spectrometer.Mar 25, 2021

When examining rock layers where do you find the oldest material?

you find the oldest material at the bottom of the rock layer because the rock layers form bottom to top.

Which is the oldest rock unit?

The oldest geologic units in the study area are the Precambrian crystalline (metamorphic and igneous) rocks (fig. 2), which form a basement under the Paleo- zoic, Mesozoic, and Cenozoic rocks and sediments.

What is the relative of oldest rock layer as stated in the principle of superposition?

law of superposition, a major principle of stratigraphy stating that within a sequence of layers of sedimentary rock, the oldest layer is at the base and that the layers are progressively younger with ascending order in the sequence.

Answer

Layer F. The bottom layer of rock is the oldest as sediments cover the existing layers of rocks over time hence the bottom layer tends to be the oldest layer.
