7. Volcanoes of the Cascade Range.

Vineyard Mt., Larch Mt., Mary’s Pk.

Corvallis ActiveDormant Extinct

7. What Oregon volcano is still considered active (erupted in last 200 years)? 7. Answer: Mt. Hood

Mt Hood is an active stratovolcano!

solid Upper Mantle plastic What is in the crust? 47% Oxygen 28% Silicon 8% Aluminum 5% Iron 4% Calcium 3% Magnesium 2% Sodium Crust Continental crust is thicker and less dense than oceanic crust. The Crust is made of solid plates that “float” on the Mantle.

8. What are the two most common chemical elements in the earth’s crust? 8. Answer: Oxygen (47%) and Silicon (28%)

8a. What are the two most common chemical elements in lava? 8a. Answer: Oxygen (47%) and Silicon (28%)

Mt Saint Helens – April 1980

Mt Saint Helens – June 1980

Belknap Crater Little Belknap Shield volcanoes in the Cascades This lava flow came from Little Belknap 1300 years ago.

Lava Flow at McKenzie Pass A’a’ – blocky lava

9. What type of volcano is this? Mt Jefferson is an extinct stratovolcano

A 4 inch “bulge” (probably caused by magma) has developed over the last 4 years on the west side of South Sister. (as of 2004) ERUPTION LIKELY?
