Vocabulary:

 * Shield Volcano:** a gently, sloping mountain gradually built from lava flows.
 * Cinder Cone:** a steep, cone-shaped hill or mountain.
 * Composite Volcanoes:** tall, cone-shaped mountains in which layers of lava alternate with layers of ash.
 * Caldera:** a huge hole left by the collapse of a volcanic mountain.
 * Volcanic Neck:** forms when magma hardens in a volcanoes pipe.
 * Dike:** magma that forces itself across rock layers.
 * Sill:** when magma squeezes between layers of rock.
 * Batholith:** a mass of rock formed when a large body of magma cools inside the crust.
 * Dome Mountains:** forms when rising magma is blocked by horizontal layers of rock.

Outline:

 * **Volcanic Landforms**
 * form- lava builds up mountains
 * form- buildup of magma beneath the surface.
 * **Landforms from lava and ash**
 * materials formed from magma- shield, composite, cinder-cone volcanoes- lava plateaus
 * shield volcanoes
 * shield volcanoes
 * cinder-cone volcanoes
 * cinder-cone
 * composite volcanoes
 * composite volcanoes
 * lava plateaus
 * Calderas
 * caldera
 * **Soils from Lava and Ash**
 * hard surface of lava breaks down soil
 * volcanic soils- riches in the world
 * volcanic ash breaks down- releases potassium, phosphorus
 * **Landforms from Magma**
 * features from magma- necks, dikes, sills, batholiths and dome mountains
 * volcanic necks, dikes and sills
 * volcanic neck
 * dike
 * sill
 * batholiths
 * batholith
 * dome mountains
 * forms when rising magma is blocked by horizontal layers of rock
