Question

what do we use a chart like this for?rock formation | agecordell dolomite | 410 - 440 myasylvania formation | 360-410 myaarenevia limestone | 360 - 410 myaglacial deposit and lake bed sediments | 0-0.01 mya1. this tells us the type of rock that is found in certain parts of michigan2. this tells us where fossils have been found3. this tells us how old a fossil is depending on what rock formation it was found in4. this tells us how many years ago cordell dolomite was living in michigan

Explanation:

The chart links specific rock formations in Michigan to their corresponding age ranges (in millions of years ago, mya). We match each statement to the chart's purpose:

1. The chart lists rock formations from Michigan, so it identifies local rock types.
2. The chart does not map fossil locations, so this is incorrect.
3. The chart ties rock formations to ages, so fossils in those rocks can be dated by their formation's age.
4. The chart gives the age range of the Cordell Dolomite formation, so it tells when this rock (and the environment it formed in) existed in Michigan.

Answer:

1. This tells us the type of rock that is found in certain parts of Michigan
2. This tells us how old a fossil is depending on what rock formation it was found in
3. This tells us how many years ago Cordell Dolomite was living in Michigan
