Key Vocabulary ANNOTATED VERSION NATURE’S FURY Volcanoes Volcanic Vocabulary 1. Volcanoes often produce cinders, charred bits of rock and ash that can coat the ground. 2. When a volcano blows its top, a huge hole or crater may be formed. 3. The force will break through the earth’s crust, or solid outer layer of earth. 5. Sometimes magma is forced upward toward the earth’s surface. This molten rock can melt the rock around it, turning it into liquid. 6. In a volcanic eruption, magma flows upward through an opening inside the earth. 7. Then lava flows out of the opening in the earth. This hot liquid rock can flow slowly or quickly. 8. A volcano can blast away the summit, or the very top of a mountain. Copyright © Houghton Mifflin Company. All rights reserved. TEACHER’S EDITION PAGE 83 TRANSPARENCY 1–20 4.
