GEOLOGY

Detailed explanation-1: -The collection of fossils and their placement in chronological order (e.g., through the location of the sedimentary layers in which they are found or through radioactive dating) is known as the fossil record.

Detailed explanation-2: -The millions of fossils that scientists have collected are called the fossil record.

Detailed explanation-3: -The totality of fossils is known as the fossil record. Paleontology is the study of fossils: their age, method of formation, and evolutionary significance. Specimens are usually considered to be fossils if they are over 10, 000 years old.

Detailed explanation-4: -The fossil record provides snapshots of the past which, when assembled, illustrate a panorama of evolutionary change over the past 3.5 billion years. The picture may be smudged in places and has bits missing, but fossil evidence clearly shows that life is very, very old and has changed over time through evolution.

Detailed explanation-5: -Fossils tell us when organisms lived, as well as provide evidence for the progression and evolution of life on earth over millions of years.
