Volcanoes Magma Reaches the Earth’s Surface KEY CONCEPT:When a Volcano erupts, the force of the expanding gases pushes magma from the magma chamber through.

I.What is a Volcano?  A volcano is any opening in the Earth’s crust where magma, ash and gas are able to reach the surface  Volcanoes may have more.

Volcanoes. What do you know about volcanoes? What would you like to know?

When subduction occurs, the crust is weakened by the collision, and cracks can form. Lava can break through the cracks and form a volcano!

Volcanic Activity. Silica  Earth’s crust and mantle are mostly made of silica The more silica in the magma, the thicker it is.

VOLCANOES How they work. WHAT IS A VOLCANO? A mountain or hill having a crater or vent through which lava, rock fragments, hot vapor, and gas are being.

Volcanic Eruptions and Hazards. What is a volcano? A volcano is a vent or 'chimney' that connects molten rock (magma) from within the Earth ’ s crust.

By Mr. D.  A volcano is a mountain that forms when magma reaches the surface of the Earth.  Magma rises because it is less dense than the solid rock.

What is a volcano? Mountains that erupt. A dormant volcano is:awake asleep ________ chamber V____ Conduit Cone Why do volcanoes erupt? Hot magma wants to go: up down How do volcanoes erupt? Two types: e and effusive. Explosive volcanoes erupt a lot of into the air. What helps make explosive volcanoes erupt?. Can lava burn trees and houses? Do effusive volcanoes have runny or sticky lava?. l a v a x p l o s i v e b u b b l e s a s h r u n n y yes e n t M a g m a
