Turning to Stone

“ Bjornerud would like readers to feel love for the Earth, but it can be difficult to get passionate about abstractions; her passion for the planet comes across most vividly in the book’s specifics. When Bjornerud explains in interesting, accessible language how plate tectonics makes Earth’s volcanoes different from those on Mars, how the appearance of vegetation altered the life cycle of sandstone, or what it is like to live in tents and study rocks in polar bear country under a midnight sun, readers can experience for themselves an earth scientist’s enthusiasm and joy in knowledge.” – excerpt from Kirkus review: www.kirkusreviews.com/book-reviews/marcia-bjornerud/turning-to-stone/
