10 what is most likely true of all the strata from the jurassic period? a they contain rocks from the jura mountains b they are more than one billion years old c they contain similar fossils d they do not contain sedimentary rock
Answer
Brief Explanations:
Strata from the same geological period often have similar fossil - assemblages as they represent a particular time when certain organisms were present. The name "Jurassic" comes from the Jura Mountains but the strata are not necessarily composed of rocks from those mountains. The Jurassic Period was about 201.3 - 145 million years ago, so not more than a billion years old. Sedimentary rocks are common in geological strata including those from the Jurassic.
Answer:
C. They contain similar fossils
