Arcview is a Geographic Information System that allows the user (YOU) to manipulate and locate digital map information. The Arcview program consists of several windows. For each window, there is an associated tool bar with buttons. Every time you click on a different window, different buttons will become available. This is important because buttons that you may need will only be available if the proper window is selected. The bar at the top of each window contains that window’s name.

Step 1

To start ArcView, double click on the ArcView icon. Once the program has opened, maximize the ArcView Window so that it takes up the entire screen. Within the ArcView window is another window titled "View 1". Make this window as large as possible without covering the window titled "Project" by clicking and dragging the lower right hand corner.

Step 2

Click on the File Menu, and select Open Project. Select the Earth project. After a few seconds, an image of the continents should appear on the screen. You will notice that the names of the windows within ArcView change. The Project window is now called Earth.apr and the View 1 window is now called World View. If an image does not appear, find World View in the Earth.apr window. Click on it so that it is highlighted and click Open.

Step 3

On the left side of the World View window is a Legend. The legend contains names (themes) with associated color-coded symbols. Circles represent earthquakes and triangles represent volcanoes. In order to activate a theme, click on it. The active theme will be outlined. The boxes with checks in them indicate themes that are visible. To make a theme disappear, click in the check box. The World View will redraw without that theme. Whenever you are trying to work on a theme, be sure that theme is activated (outlined).

Step 4

Each theme is linked to a table containing data. In order to view a table, activate the desired theme and click on the tables icon . A table should appear. Resize the table or use the scroll bars to view all of the records.

Step 5

Look at the tables for each of the individual earthquakes listed on the Legend (you will have to open each of their tables). What was the largest magnitude earthquake? What country was it located in? What continent(s) are the countries located in?

Step 6

Which 2 earthquakes resulted in the fewest deaths? Why do you think fewer deaths occurred here than in other locations?

Step 7

What is the Richter scale difference between the lowest and highest magnitude earthquakes? Approximately how many times stronger is the highest magnitude earthquake?

Step 8

Using the latitude and longitudes provided in the five volcano themes, determine which volcano is the farthest south. Which is farthest west? Which is the tallest? In what countries are these volcanoes located?

Step 9

Close any tables that are still open. Open the table for the theme named 'Volcanoes'. List five different types of volcanoes. To view images of the volcanoes, go back to the World View window, click on a theme, click on the Hotlink tool  and then click on the theme symbol (the triangle) on the map. An image should appear. Use these images to help you describe the difference between the various types of volcanoes. Compare one of the stratovolcanoes (Mt. Fuji) to a caldera (Krakatau). What are the differences in the ways these volcanoes form?

Step 10

Judging by the locations of the volcanoes in Japan, which way do you think the Pacific Plate is moving?

Step 11

Select the Volcanoes theme. Click on the Table Button. Click on the Query button . An Attributes of Volcanoes window should appear. Double click on elevation in the "Fields" column, then click the equals sign. In the "Values" column, scroll down to the bottom to find the highest elevation and double click on that value. Then click on the "New Set" button. The volcano with the highest elevation should be highlighted on the table. In the World View window, zoom in on the Continent in which this volcano is located by using the Zoom to Selected Features button . The selected volcano should appear as a yellow triangle. Go back to the table to answer the following questions. What is the volcano? How high is it? What type of volcano is it? Now click the Unselect button  to be sure no records are selected. Now it is your turn to find the smallest volcano above sea level (not a negative value).

Step 12

Do your own query by choosing any field and value. (For example, choose a Volcano by name).

Step 13

The Measure Distance tool allows you to measure either straight line or curved distances. First we'll measure the distance between Mt. Kilimanjaro and Mt. Vesuvius. Using the Zoom tool , click and drag to select a rectangle on the map that includes both of these volcanoes. If you make a mistake just click on the Zoom to Full Extent button  and try again. Now click on the Measure Distance tool . Click once on Mt. Kilimanjaro. As you move your cursor towards Mt. Vesuvius you should see a line being dragged from Mt. Kilimanjaro. Double click on Mt. Vesuvius. In the lower left corner of the ArcView window you should see a "Segment Length". How far are these two volcanoes from each other?

Step 14

Now we'll measure a non-straight-line distance. Make sure the Volcanoes theme in the legend is selected. Use the Zoom to Selected Features button to zoom out. Use the Zoom Tool to zoom in on a rectangle that includes the solid string of volcanoes that starts in Korea and goes south to the Western Pacific Islands. Select the Measure Distance Tool. Starting at the southernmost volcano click once. Follow the chain of volcanoes clicking once each time there is a curve in the

chain so that you have a line that follows the chain of volcanoes. When you reach the northernmost volcano double click on it. Look in the lower left corner of the ArcView window to see how far it is. If you want, find out how long the Atlantic coast of Africa is starting just across from Spain and going all the way to Cape Town, South Africa.

Step 15

Click on the Identify tool . Make sure the Volcanoes theme is active. Choose a volcano on the map and click on it (zoom in if necessary). An "Identify Results" window should appear. What is the volcano’s name? Elevation? Latitude and Longitude?
