BUYING ADVISORY: EL, MS, HS - ADVISABLE
APPEALS TO: SEVERAL
Rock teaches us not just about the different kinds of rocks and crystals, but also takes us through his own millenial long journey - through earth’s mantle to the crust and through different phases of its existence.
90% of Slivensky’s book is excellent - it is 100% interesting to look at and very clear and engaging. My Earth Science teachers (7th grade) did have a couple of little problems - early on (1.8 billion years) it shows the continents and the plates as we know them today. Several pages later (325 million years) it shows a supercontinent, which we assume is Pangea; we feel it would have been clearer if those two things were reversed. The other detail was the page showing, as it said, erosion - the little rock rolling down the hill. The teachers had a great debate about whether the definition is actual for weathering, not erosion - but the rock bouncing is showing erosion. That’s my teachers’ two cents. Otherwise, they still want to the book so that they can use it in their teaching.
