PART 1
THE KILLERS ! World’s most active volcanoes (5 pts. each)
Open this link in your Web browser:

Mt. Merapi is not one of the 5 most active (but could become one).
On the Web page, use the NEXT button to move through the 5 most active volcanoes.
I have placed Mt. Merapi with an orange dot. Copy and paste the dot 5 times, and place these dots in the correct places for the world’s 5 most active volcanoes.

PART 2
SHIELD VOLCANOES vs. COMPOSITE VOLCANOES (5 pts. each)
Read the passage in your textbook about shield (basaltic) volcanoes and composite (strato-) volcanoes. There's also a good introduction at http://www.geology.sdsu.edu/how_volcanoes_work/Volcano_types.html
1. What is the main difference between the two types?Composite volcanoes steep sided symmetrical cone with heights over 3700M. Shield volcanoes are broad, gently sloping mountain, much broader than high; size varies.
2. Use Google Earth to fly to Hawaii. :-)
Find Mauna Kea (on the island of Hawaii, not Oahu).
Let's assume arbitrarily that Mauna Kea extends from 19 deg 55' N (no seconds) to 19 deg 45' N. (It's actually much bigger than that but there's no real "end" -- all these lava flows blend together). [Show Less]
