Olson, Elsie

Exploring the Rock Cycle: Petrologists at Work!

(4) K-3 Earth Detectives series. Olson's cursory introductions to different earth-science disciplines first define each field, then shift to discussions of the scientific research and methods used. One famous historical scientist is always profiled, then the laboratory and field work of today's practitioners are described; accompanying photographs feature the landforms and earth materials discussed plus important scientific tools. Back matter offers career advice and tests readers' comprehension. Glos. Review covers these Earth Detectives titles: Exploring Earthquakes, Exploring Fossils, Exploring Minerals, Exploring the Rock Cycle, Exploring Volcanoes, and Exploring Weather.
