Volcanoes and Eruptions

Volcanoes By Nicole Kawamoto. What is a Volcano? A volcano is a mountain that opens downward to a pool of molten rock below the surface of the earth.

Volcanoes form as molten rock erupts

Volcanic Eruptions. Mafic Lava  Dark colored  Rich in magnesium and iron  Formed from oceanic crust  Cools rapidly.

Volcanoes Chapter 10 - mountains created by rising magma Types 1. Shield volcano - large, dome-shaped volcano - ex. – Hawaiian Islands 2. Cinder volcano - small volcanoes caused by a single eruption 3. Composite Cones - steep volcanoes along Earth’s “ring of fire”

Shield Volcano

Cinder Cone Volcano

Composite Volcano

Mount St. Helens

Volcano Profiles

Volcanic Material 1. Lava - basaltic lava – fast flowing - silica-rich lava – very slow moving 2. Gases - Water vapor, carbon dioxide, nitrogen, and sulfur. 3. Pyroclastic Materials - solid fragments erupted from volcanoes

Basaltic Lava (fast)

Silica-rich Lava (slow)

Volcanic Landforms 1. Crater - the top of a volcano 2. Pipes(Conduits) - underground tunnels that magma flows through 3. Neck - cooled magma in pipes that break Earth’s surface (look like rock towers)
