Annotation: "On Earth, everything is connected, even if we can't see it right away. Biogeology is the study of the important-and sometimes weird-relationships between living things and the Earth itself. Young readers might know how beavers dam rivers to make ponds. But they might not know about the hungry bacteria that eat rocks to make sparkly minerals like pyrite, also called fool's gold! This fun, fact-filled title reinforces essential science concepts with surprising examples and eye-catching art. Young scientists are also introduced to the causes and effects of climate change"-- cProvided by publisher.
