Which Of The Following Statements Accurately Describes The Relative Age Of The Fossils In These Rock Brainly Com

Which statement best describes the process of absolute dating.

. Each sedimentary layer of rock represents 1000 years of Earths age much like the rings of a tree. Scientists uncover mammoth bones and are able to determine the amount of carbon-14 in the bones. The latter method of rock dating can be determined by radioactivity.

Rock dating is determined by either Relative Dating or Absolute Dating. Different methods of radiometric dating can be used to estimate the age of a variety of natural and even man-made materials. A fault or igneous inclusion that cuts across a rock layer occurred after that rock layer formed.

Carbon-14 dating is an example of relative dating and the law of superposition is an example of absolute dating. In undisturbed layers of sedimentary rock. These can later tilt and fold due to tectonic activity and river cuttings can cause gaps among the layers.

What are the 5 principles of relative age dating. Correct A break eg. B carbon-14 with a half-life of 5700 years.

In undisturbed layers of sedimentary rock the upper rock layers are older than the lower rock layers. All of the layers of rock were deposited at about the same time and are about the same age. Fault A breaks through to the surface whereas fault B does not.

Both faults cut through all five layers of rock. Find and create gamified quizzes lessons presentations and flashcards for students employees and everyone else. Which best explains the use of carbon-14 in studying the.

Relative dating is using the rock layers and fossil records to determine the age of the rock and it is not the actual age of the rock. The oldest rock layer is found on top and the younger layers are. Geologists are able to read the rock layers using relative and absolute dating techniques.

The position of the layer is the best indication of the relative age of a rock layer. Fossils formed during a time when chemical processes operated differently. The oldest layers of rock and soil are closest to the surface of the earth.

Most sedimentary rocks are laid down in flat horizontal layers. The youngest layers of rock and soil are farther away from the surface of the earth. The former method of rock dating can be determined by looking at its layer position.

Which of the following best describes the use of relative dating. Here are some facts involving Rock Dating. One of the principles used for relative dating is the law of superposition.

Which of the following statements about faults A and B is most accurate. Faults A and B are about the same age and both are younger than the five layers of rock. A is an intrusion so it must be younger than layers 1 and 2.

Sea otters and sea urchins have a predatorprey relationship. 1 2 A 3 B 4 C According to the law of superposition layer 1 is the oldest sedimentary layer and layer 4 is the youngest sedimentary layer. Radiometric dating or radioactive dating as it is sometimes called is a method used to date rocks and other objects based on the known decay rate of radioactive isotopes.

C plutonium-238 with a half-life of 88 years. The youngest rock layer is found on top and the older layers are closer to the center of Earth. Which describes the law of superposition used to find the relative age of fossils in rocks.

Kelp and sea otters have a predatorprey relationship. Fossils inside a layer of a rock older than the surrounding rocks B. D iodine-129 with a half-life of 16 million years.

Which of the following best describes this principle. Five layers of rock are cut by two faults. Older sedimentary rocks layers are found below younger sedimentary rock layers.

A gallium-67 with a half-life of 78 hours. It measures the age of a rock by comparing it to fossils found in the same stratigraphic layer as the rock. To determine the sequential order in which prehistoric and geologic events occurred.

B is an intrusion so it must be younger than layers 1 2 and 3. The fossil organisms found at the bottom of layer C lived before rock layer B was deposited. Absolute dating is the actual date of the rock and can also been known as radioactive dating.

Relative dating arranges geological events and the rocks they leave behind in a sequence. What principle of stratigraphy is shown by the relationship between layers 1 through 4. Solve for brainliest thank 5 star Which statement correctly describes the interaction between the organisms shown in the food chain.

Fossils of the same organism found at different locations formed in similar climates. It compares the amount of radioactive material in a rock to the amount that has decayed into another element.
