Is gasoline radioactive?

Oil is not generally radioactive unless it was originally located near radioactive material when it was extracted. More often, it only becomes radioactive when exposed to or stored near radioactive materials post processing.


Are fossil fuels radioactive?

No, fossil fuels are not radioactive. Fossil fuels like coal, oil, and natural gas are formed from the remains of plants and animals that lived millions of years ago. Radioactive materials are not part of the formation process of fossil fuels.


Why is an original material fossil so valuable to a paleontologist?

An original material fossil is valuable to a paleontologist because it provides direct evidence of the ancient organism without alteration or interpretation. It allows researchers to study the physical characteristics, biology, and environment of the organism with greater accuracy. Original material fossils are rare and can provide unique insights into our understanding of prehistoric life.


Why is a dinosaur fossil heavier than the original?

Part or all the organic material has been replaced by "rock".


A fossil made of hardened minerals in the solid shape of the original organism or one of its parts is called an?

A fossil made of hardened minerals in the solid shape of the original organism or one of its parts is called a petrified fossil. This process occurs when the organic material is replaced by minerals, preserving the original structure of the organism.


What is a hard and rock-like fossil?

A hard and rock-like fossil is called a petrified fossil. Petrified fossils are formed when organic material is slowly replaced by minerals, turning the material into stone while preserving the original structure of the organism.


What forms when a fossil mold is filled?

When a fossil mold is filled, it forms a fossil cast. The cast is a replica of the original organism or object that created the mold, made of the same material as the original organism or object. Fossil casts are valuable in paleontology for studying the morphology of ancient organisms.


What is in the process in which minerals replace tissues?

In geology, petrification or petrification is the process by which organic material becomes a fossil through the replacement of the original material and the filling of the original pore spaces with minerals. So yeah the answer is petrification

What is the type of fossil called where there is a molecule-for-molecule replacement turning the original object into a rock like object?

The type of fossil you are referring to is called a petrified fossil. Petrification occurs when minerals such as silica or calcite replace the organic material of the original object, transforming it into a rock-like structure while retaining its original shape and features.


How does a petrified fossil form?

When an organism is buried in sediment over time, minerals gradually replace the original organic material. The minerals create a stone cast of the organism, preserving its original structure. This process is known as petrification, resulting in a petrified fossil.
