lithosphere that makes up part of a continent.
Acraton is a large, stable portion of earth's
lithosphere that makes up part of a continent.
the kaapvaal craton in africa is one of five
ancient cratons left from the precambrian era.
the rock has remained tectonically stable since
its formation 3.6 billion to 2 billion years ago.
what do you think the term "tectonically stable"
means? why do you think this rock formation is
important to understanding the history of earth?
do you think studying ancient rock formations
such as the kaapvaal craton can teach scientists
not only about earth's past but also its future?
why or why not?

15 points need quick 1. looking at your graph and the geologic time scale during what period did this rock form? what is the age span of the rock, in millions of years? 2. this rock sample is limestone and shale. with what you know about rock formation, what type of environment did these organisms live in? 3. if some of these fossil samples were found in a rock also containing leaf fossils, could you use radiocarbon dating to determine the age of this rock? explain.
