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?

Lava collects in the crater, the bowl-shaped area that forms around the volcano’s vent.

The point on the surface where magma leaves the volcano’s

pipe is called the vent.

Sometimes magma forces its way out of a volcano

through a side vent.

Magma that reaches the surface is called lava

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

As magma rises toward the surface, it forms a large

underground pocket called a magma chamber

Magma is extremely hot, molten material that also contains dissolved gases

including water vapor

THE ANATOMY OF A VOLCANO

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!

1. How did the volcano behave the day before the eruption?

2. Describe how the volcano reacted during the eruption

3. 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
