Why cant geologist use the carbon-14 method to date igneous rock and date dinosaur bones?
Geologists cannot use the carbon-14 method to date igneous rocks and dinosaur bones because carbon-14 dating is effective only for organic materials and samples that are less than about 50,000 years old. Igneous rocks form from molten material and do not contain organic carbon, while dinosaur bones, though they are biological in origin, typically date back millions of years, far exceeding the maximum effective range of carbon-14 dating. Instead, other dating methods, such as uranium-lead or potassium-argon dating, are employed for these materials.
Which of these can form fossils bones and leaves skin hair and muscles composite rocks and plants igneous and sedimentary rocks?
Bones, skin, hair, and muscles can form fossils within sedimentary rocks when the remains are buried and undergo a process called fossilization. Leaves can also form fossils in sedimentary rocks through a similar process. Igneous rocks, being formed from molten magma, are less likely to preserve fossils. Plants can form fossils through a process called carbonization, where their structures are preserved in sedimentary rocks.
Why is carbon dating ineffective in determining the age of a dinosaur bone?
Carbon-14 isotope dating is only effective up to about 70,000 years. Dinosaur bones are at least 65 million years old. Elements with much longer half-lives are used to radiometrically date rock associated with dinosaur remains.
What are animals or plants preserved in sedimentary rocks?
Fossils of animals or plants are commonly preserved in sedimentary rocks. These fossils form when the remains of organisms are buried in sediment, which gradually hardens into rock, preserving the shape and structure of the original organism. Examples include dinosaur bones in sandstone or fern leaves in shale.
What can organic sedimentary rock formed from layers of bones and shells form?
Limestone
Why are dinosaur bones rare?
Dinosaur bones are rare because the outside of the bone is actually dissolved so when the bone was still there, the pores let in sedimentary rock which hardened and the bone dissolved. THe bone you see in museums are actually rocks in the form of the bone. Thats why dinosaur bones are extremely rare.

What type of rocks have fossils found in them?
Fossils are nearly always found in some type of sedimentary rock. Limestone is a sedimentary rock which very commonly contains fossils, as is coal.
Are dinosaur bones radioactive?
No, dinosaur bones are not radioactive.
How many bones does a dinosaur have?
I think a dinosaur has 985 bones
When was Dinosaur Bones created?
Dinosaur Bones was created in 2008.
How do you make a dinosaur project?
You can make a dinosaur project by going into your backyard and looking for dinosaur bones. When you find the dinosaur bones you can determine what kind of bones they are as a project.
Do you have to go to a Dinosaur did to dig for dinosaur bones?
No, because dinosaur bones called fossils are the skeleton of a dinosaur. The skeleton is there because all dinosaurs are extinct.
What peninsula were dinosaur bones were discovered?
On what peninsula where dinosaur bones discovered?
Are dinosaur bones made of gas?
No. Bones are solid.

How is carbon dating used to determine the age of dinosaur bones?
Carbon dating is not typically used to determine the age of dinosaur bones because dinosaurs lived millions of years ago, beyond the range of carbon dating which is effective up to about 50,000 years. Instead, other methods like radiometric dating are used to determine the age of dinosaur bones by measuring the decay of radioactive isotopes in the fossils.
