water.

(Major Volcanic Eruptions
Edition)
Anak Krakatau “Child of Krakatau”
Krakatau, Indonesia
•
•
•
•
August 26-27, 1883
Casualties: 36,000-40,000
Major Cause of Death: Tsunamis
The force of this eruption was so great
that much of the volcano, and two-thirds
of the island itself, collapsed into the
sea, triggering 120-foot waves that
devastated neighboring islands.

Work on 3.1 daily work item
* *Mountain Maker packet will be
collected today**
3. Summarize Mountain Types
Mountain Types
1. Folded
2. Fault Block
Folded Mountain
Ex. Himalaya Mountains
Folded Mountain:
A mountain that forms as continental crust
crumples and bends into folds.
Conditions needed:
• Hot temperatures & High pressure
• Slow, continual stress
Plate Boundaries:
Convergent Boundaries
• Continental-continental collision
• Oceanic-continental collision
Fault-Block Mountains
Ex. Grand Teton Range, WY
Ex. Sierra Nevada Mtns., CA
Grand Teton Mountains (WY)
Fault-Block Mountains
Mountains that form as blocks of rock move
up/down along normal faults.
Conditions needed:
• Cool & rigid crust
• EQ shift rock blocks
Plate Boundaries:
Divergent Boundaries
• Crust stretched & breaks into blocks
• Blocks tilt forming mtns and valleys
Laws of Play-doh
1. The play-doh shall be shaped on the
waxed paper only.
2. Use play-doh for good not evil
purposes.
3. All play-doh shall be cleaned up before
leaving.
What we are doing today:
1. Assemble Mt. Play-doh & create
topographic map.
2. Finish Analysis questions in Mountain
maker packet.
• Finished Mountain Maker packets
due tomorrow (Tues.)!!!

Additional Vocab:
• Pahoehoe: A Hawaiian term to
describe a type of lava. “Ropy, cakebatter lava”
Science Starter: (on back of
coversheet)
In a Venn Diagram, explain the
similarities & differences between
fault block mountains and folded
mountains.
Fault Block
Folded
Volcano Vocab. (not in book)
• Silica: (Silicon + Oxygen) Building
block of volcanic rocks that controls
how well lava flows. The more
silica--> the greater viscosity
(stickiness)
Viscosity Challenge
* Brought to you by: Silica
• Felsic: Term used to describe
volcanic rock or lava composed
largely of silica. (ex. Aa)
• Mafic: Term used to describe
volcanic rock or lava that does not
have much silica. (ex. Pahoehoe)
Quiet, Independent Work
Time (~ 25 min.)
Please work quietly on the following:
1. Back of green volcano comparison

• Viscosity: A measure of how well a
substance flows.
• Lahar: A flowing mixture of watersaturated rock that forms on a volcano
& flows downhill.
• Caldera: A huge crater or hole formed
by the collapse of a volcano when
magma rapidly erupts from underneath
it.
