Lava Story

Magma that reaches the surface is called:

• Vent
• Hot spot
• Lava
• Cinders

The belt of volcanoes around the rim of the Pacific Ocean is called:

• Island arc
• Ring of Fire
• Lava plateau
• Hawaii

Shield volcanoes have:

• gently sloping sides
• a steep cone shape
• moderately sized sides
• long cracks along plate boundaries

When a volcano erupts, empties the magma chamber, and collapses the top leaving a huge hole.

• Dike
• Caldera
• Silica
• Geyser

Explosive eruption that hurls ash, gases, cinders, and bombs from the main vent.

• Volcano bomb
• Geyser
• Geothermal energy
• Pyroclastic flow

Inside a volcano, magma collects in a pocket called a:

• caldera
• pipe
• magma chamber
• vent

Magma's resistance to flow, or how thick it is, is called:

• silica
• viscosity
• hot spot
• caldera

The Hawaiian islands are made from this type of volcano.

• Composite
• Cinder Cone
• Shield
• Big

An opening through which the lava flows is called:

• crater
• caldera
• vent
• pipe

This common type of volcano is made up of alternating layers of ash and lava.

• Shield volcano
• Composite / Stratovolcano
• Cinder cone
• Fissure volcano
