Question

distinguish between the cambrian time period and the jurassic time period​

Answer 1

The geologic timeline (also called the geologic time scale) is a system of measurement commonly used by earth scientists. It relates rock strata to time, providing a rough history of geology and life (through the fossil record) on Earth. The geologic timeline is vast, stretching from the formation of the Earth approximately 4.5 billion years ago to the present day and into the future until the destruction of the Earth. Stratigraphers kindly divide it into various eons, eras, periods and other denominations to make studying it more practical and to distinguish unique periods of time.
