Exploring Planet Earth
Another fascinating book for junior high readers. Following in the footsteps of early explorers, we look at interesting features of our globe such as wind, currents in the sea, the tides, earth’s magnetic field, rocks, glaciers, and river systems. Later we move to the atmosphere and exploration by hot air balloon, airplanes and space vehicles. Thought provoking questions at the end of each chapter make this book suitable for geography and social studies (history).
