Explain two ways in which scientists use fossils to determine environmental change
drek231 [11]
Hello.  Happy to help.

1)  Coast Lines:  The location of marine fossils can help determine where and when ancient coast lines were in the past.2)  Climates:  Fossils can be used to determine the past climates.  (Was an area cooler or wetter than the present.)

The presence of marine or land fossils indicates whether the land at one time was at the bottom of the ocean or not.

Also, you could mention radioactive dating and relative dating.  I am sure that is mentioned in your curriculum. 

Hope that helps.
