OBJECTIVE AND STARTER Objective: Today you will learn about volcanoes and why they form. Starter-What can cause a volcano to form?

Background Information Have you ever seen a volcano? What was happening?

Volcano A weak spot in the crust where molten material or magma comes to the surface.

Magma A molten mixture of rock forming substances, gases, and water from the mantle.

Lava When magma reaches the surface.

Ring of Fire Many volcanoes that rim the Pacific Ocean. A major volcanic belt.

Island Arc A curved chain of volcanic islands. They form in the overriding tectonic plates of subduction zones as the result of rising melt from the down going plate

hot spot An area where material from deep within the mantle rises then melts, forming magma.

OBJECTIVE AND STARTER Objective: Today you will learn about landforms that are created by volcanoes. Starter: What does the interior of a volcano look like and have?

OBJECTIVE AND STARTER Objective: Today you will go to the computer lab and work on the Pangea project. Starter: What does the interior of a volcano look like and have?

Background Information What shape is a volcano? Are all volcanoes shaped like this?

Shield volcano Usually built almost entirely of fluid lava flows. They are named for their large size and low profile, resembling a warrior's shield. This is caused by the highly fluid lava they eruptfluid warrior's shield

Cinder Cone A steep hill like volcano that slopes steeply.

Composite Volcano A volcano built up by many layers (strata) of hardened lava pumice and volcanic ash.

Caldera The huge hole left by a volcanic mountain.

Volcanic Neck It looks like a giant tooth stuck in the ground. Forms when magma hardens a volcanoes pipe.
