Fossils are often said to take a million years to form. However, as of 2014 it has been proven that a fossil can take a shorter period of time to form. This period can be a thousand years or less. The earliest fossil discovered dates back to about 3.5 billion years; however, there are fossils that have been discovered to be only a few years old.Know More
Fossils are the preserved marks or remains of plants or animals that lived in the geologic past. They are formed through a naturally occurring process known as fossilization. Fossils form from animal tracks or bones embedded on the earth’s crust. Fossils can be found on land and beneath water bodies, such as lakes and rivers.
There are different types of fossils, including mold fossils and cast fossils. However, the two main types are trace fossils and body fossils. Trace fossils consist of marks left behind by an organism, such as teeth marks or footprints, while it was alive. Body fossils consist of parts of an organism, such as bones, teeth or claws.
The fossilization process varies according to external conditions and tissue type. The various types of fossilization processes include permineralization, bioimmuration, adpression, replacement and recrystallization, cast and molds.Learn more about Anthropology
Fossil fuels are formed the gradual accumulation of organic remains on the sea floor. As the accumulation rate increases, the organic remains are subjected to heat and pressure, which leads to fossil-fuel formation.Full Answer >
Fossil fuels are the remains of organic material, such as plants and animals, which lived millions of years ago. Different fossil fuels are created depending on how long the material is buried, but it is generally accepted that the process takes millions of years.Full Answer >
Fossil fuels store sunlight, which derives from plants using energy from the sun for photosynthesis. This light energy remains dormant in fossil fuels and dates back many years. Fossil fuels release this energy upon activation, such as burning.Full Answer >
Both cuneiform and hieroglyphs were developed around 4000 B.C. Among the earliest forms of writing, they both began as pictographic forms which over time became more abstract and included phonetic elements.Full Answer >
