The cool story of volcanoes will intrigue kids and adults alike. Hot melted rock from the middle of our planet forces its way up through cracks in the EarthÆs crusts, exploding violently and sometimes unexpectedly in volcanic fury that can terrorize populations for months, even years. Anne SchreiberÆs narrative gives readers a little of the science, a little of the history, and a lot of the action. National Geographic photography fires the imagination on dramatic spreads alive with vivid images of lava, ash, molten rock, weird rocks, and steaming seawater. A Step Into Reading Book--Step 2: Reading with Help books have basic vocabulary, short sentences and simple stories. Paperback, 6" x 9"
