Label the year and name of each geologic area on your geologic time scale. Using the 1 cm = 10 million years scale, figure out and measure each distance below from the PRESENT line.
Pre-Cambrian Era = 4.6 Billion years ago = _______________________ cm from PRESENT
What would be number?

If 10 million years ----> 1 cm
4.6 billion/(10million) = 4.6 x 10^9/(10 x 10^6) = 460
You will need 460 cm or 4.6 metres
4.6 billion/(10million) = 4.6 x 10^9/(10 x 10^6) = 460
You will need 460 cm or 4.6 metres
