NO. 1) Carbon is not a common component of rocks. 2) C14's half life is too short.

Why is the canadina shield called the precambrian?

The term "Precambrian" refers to the time period before the Cambrian period, dating back over 4 billion years. The Canadian Shield is composed of some of the oldest rocks on Earth, dating back to the Precambrian era. Its name reflects the ancient age of the rocks and landforms that make up the shield.


What accurately characterizes precambrian rock?

Precambrian rocks are the oldest rocks on Earth, dating back over 4 billion years. They often contain minerals such as quartz, feldspar, and mica, and can exhibit a wide range of colors and textures. These rocks can provide valuable information about the early Earth's geology and the processes that shaped our planet.


How do you carbon date rocks 10 million years old?

You cannot. Carbon dating is not useful for dating things more than about 50,000 years old. You would have to use a different radioisotope to date something 10 million years old. Potassium-Argon dating would work for some rocks.


Why is it difficult to interpret the rock record of precambrian time?

It is difficult to interpret the rock record of Precambrian time because the rocks from this era have been heavily altered and modified over billions of years due to tectonic activity, metamorphism, and erosion. Additionally, the lack of well-preserved fossils and the scarcity of reliable age-dating techniques make it challenging to accurately determine the age and history of Precambrian rocks.


What are two charateristics of precambrian rock?

Precambrian rocks are typically very old, dating back over 600 million years. They often contain minerals like quartz, feldspar, and mica due to their formation process in the early Earth's crust.

Why is the isotope carbon-14 so helpful in dating rocks?

It is not useful in dating rocks. Only organic substances in terrestrial conditions. No carbon in rocks.

When were precambrian rocks formed?

During the precambrian.


What is the Difference between Precambrian rocks and Paleozoic rocks?

Precambrian rocks are older than Paleozoic rocks, dating back to about 4.6 billion to 541 million years ago, while Paleozoic rocks were formed from 541 to 252 million years ago. Precambrian rocks lack fossils, while Paleozoic rocks contain abundant fossil evidence of early marine life. Additionally, Paleozoic rocks mark the beginning of complex life forms, whereas Precambrian rocks mainly consist of simpler organisms.

How will you determine the age of rock and mineral by carbon dating?

Carbon dating is not typically used to determine the age of rocks and minerals. Instead, techniques such as radiometric dating, which relies on the natural decay of radioactive isotopes, are more commonly used for this purpose. These methods can provide more accurate age estimates for rocks and minerals over a wider range of time scales.
