The rock samples collected from the bottom of the drill hole came from which earth layer?
The rock samples collected from the bottom of the drill hole likely came from the Earth's crust or upper mantle layer, as drill holes typically do not penetrate beyond the uppermost layers of the Earth's lithosphere. To determine the exact layer, further analysis of the composition and characteristics of the rock samples would be necessary.
What is conventional coring?
Conventional coring is a method used in geology and oil drilling to obtain rock samples from underground formations. It involves using a hollow drill to extract cylindrical cores of the rock for analysis. These core samples help geologists and engineers understand the composition, structure, and other properties of the rock layers.
Explain how an index fossil can be used date rock.?
Index fossils are fossils of organisms that lived for a relatively short period of time but were widespread geographically. By identifying these index fossils in a particular layer of rock, scientists can determine the age of the rock and correlate it with other rock layers containing the same index fossils. This allows for the relative dating of rock layers based on the presence of specific index fossils.
What are two types of evidence geologists use to learn about Earths interior?
Rock samples and Indirect evidence from seismic waves Direct evidence from rocks samples and indirect samples from seismic waves my science teacher told me
What is Radioactive dating of rock samples?
Radioactive dating of rock samples determines the age of rocks from the time it was formed. Geologist determine the age of rocks using radioactive dating. The radioactive dating relies on spontaneous decomposition into other element. The spontaneous decomposition is called radioactive decay.
Scientists use radioactivity in rock samples to measure?
Scientists use radioactivity in rock samples to measure the age of the rock by determining the decay of isotopes. By measuring the ratio of parent isotopes to daughter isotopes in a sample, scientists can calculate how much time has passed since the rock formed. This technique is called radiometric dating and is commonly used in geology and archaeology to determine the age of rocks and artifacts.
Explain why there are no rock samples until 4 billion years ago?
No rock samples have been found so far that are older than 4.2 billion years.Maybe that says something about the age of the earth, do you suppose ??
Where do scientists get rock samples to discover earth's interior?
They recover rock samples from volcanic eruptions.
Why did the earliest rock samples date from 800 Million Years After Earth formed?
earth cooled suffciently
How do astronauts bring rock samples back from Mars?
No astronauts have ever been to Mars, and no rock samples have ever been sent to Earth.
What process dates rock and minerals by the radioactivity isotopes they contain?
carbon dating
When explorers visit caves what do they collect?
rock samples
What do explorers collect when they visit a cave?
rock samples
How do scientists find the absolute age of fossils and rock correlations?
Scientists find the absolute age of fossils and rocks through radiometric dating techniques such as carbon-14 dating for more recent samples, and methods like uranium-lead dating for older samples. Rock correlations involve comparing the rock layers in different locations to establish their relative ages based on the principle of superposition and the identification of index fossils.
Is radioactive decay used to find the absolute age of a rock?
its not from radioactivity its from carbon dating
There is a future mission to Mars planned that will send a spacecraft to collect rock samples on the surface of the planet What is the name and the launch date of this spacecraft?
The future mission planned to collect rock samples on Mars is the Mars Sample Return mission. The exact launch date has not been confirmed yet, but it is expected to take place in the late 2020s or early 2030s.
Which of the rock samples is the oldest?
hey that call waz up
