## Description

• View the two maps
• The following instructions
• Calculating slope:
• The innermost loop on each map is the center of the volcano. On the Mt. Saint Helens map, pick two points along the black line B-B’ where two different brown lines cross the black line. It doesn’t matter which two brown lines you choose as long as they are on the same side of the volcano (same side of innermost loop).
• Determine the values of the two brown lines you chose. Notice the values of some brown lines are on the map. Subtract the two. Include units of feet.
• Next determine the distance between the brown lines you chose. Lay the edge of a piece of scratch paper across line B-B’. Put a tick mark at the two brown lines you chose. Now pick up the piece of paper and lay it across the scale. How many miles did you get? You will need to estimate.
• Multiply your letter “c” answer by 5280 since there are 5280 feet in 1 mile.
• Now divide letter “b” answer by letter “d” answer. Since you have feet divided by feet, the units cancel out (no units). Your answer will be a number (decimal) less than 1.
• Do the same process for Mauna Loa.
• Determining the distance across the volcano: make sure you measure all the way across the entire box from corner to corner (not the length of the black line).
• Determining relief: you’ll either need to add or subtract. You’ve already determined the maximum elevation (value of the innermost loop on each volcano). Now either add or subtract the values given to you in the box depending on whether the base of the mountain is below or above sea level.

Hello. I have filled all the questions from the Assignment. Please check attached. Thank you and welcome back. For any clarification, I am available here.

Volcano Activity

Name:___________________________

Purpose: The purpose of this activity is to identify volcano types based off size, shape, slope and
to associate hazards with volcano types.
Knowledge gained:
• Associate magma chemistry with the volcano type.
• Associate volcano type with tectonic setting.
• Determine which hazards are associated with which type of volcano.

Activity I: Comparing two volcanoes (Mt. Saint Helens, Washington and Mauna Loa, Hawaii)
• View the two maps on the next page. You’ll be completing the table on page 3.
• The following instructions are for some of the more challenging questions in the table on
page 3.
o Calculating slope:
a) The innermost loop on each map is the center of the volcano. On the Mt. Saint
Helens map, pick two points along the black line B-B’ where two different brown
lines cross the black line. It doesn’t matter which two brown lines you choose as
long as they are on the same side of the volcano (same side of innermost loop).
b) Determine the values of the two brown lines you chose. Notice the values of some
brown lines are on the map. Subtract the two. Include units of feet.
c) Next determine the distance between the brown lines you chose. Lay the edge of a
piece of scratch paper across line B-B’. Put a tick mark at the two brown lines you
chose. Now pick up the piece of paper and lay it across ...

Just the thing I needed, saved me a lot of time.
