Here’s What Your Map Should Look Like

Let’s Review Our Answers 1 & 2) Both earthquakes and volcanoes are concentrated in definite zones. 3) Earthquakes and volcanoes tent to occur in the same areas 4) The west coast of North America has the greatest risk of both earthquake and volcano damage. Urban planners, engineers, and builders should use this information when placing and designing structures.

Think back to yesterday… What did we notice about where volcanoes form?

THE ANATOMY OF A VOLCANO What’s This? Lava collects in the crater, the bowl-shaped area that forms around the volcano’s vent. What’s This? The point on the surface where magma leaves the volcano’s pipe is called the vent. Magma that reaches the surface is called lava What’s This? What’s This? Sometimes magma forces its way out of a volcano through a side vent. What’s This? The river of lava that pours down a volcano and over the land is called a lava flow. A pipe is a narrow, almost vertical crack in the crust through which magma rises to the surface What’s This? What’s This? What’s This? Magma is extremely hot, molten material that also contains dissolved gases including water vapor As magma rises toward the surface, it forms a large underground pocket called a magma chamber

Please Take out the Following Supplies: 1 Pencil Red, Orange, & Brown Crayons/Markers/Colored Pencils 1 Index Card

The Anatomy of a Volcano On the back of your handout, you will draw and label a volcano from the inside out The first thing you should draw is an east/west line across the bottom of the page, about 5 cm from the bottom…It will represent the border between the crust and mantle. You will then draw a cone shape to represent the slopes of the volcanoes sides. Use the key words below to help you determine where to draw the interior parts of a volcano: Pipe…Vent…Side Vent… Magma Chamber… Magma…Lava Flow…Crater…Lava Don’t forget to name your volcano!

Once your sketch is complete… On your Index Card, please write: Your First and Last Name 6-1/6-2 …Use your imagination and prior knowledge about volcanoes to answer the following questions! …BE CREATIVE! How did the volcano behave the day before the eruption? Describe how the volcano reacted during the eruption What did the area surrounding the volcano look like after the eruption? (HINT: Think of the video we watched in class about the lifespan of a volcano…Think of how it changed as time progressed…)

HOMEWORK Complete your volcano diagram and attach your index card(s) with your responses to questions 1-3 Read pages 183-185 Please do not complete your reading until you’ve finished your diagram
