Geography
The Land Of Volcanoes
Alexandra Anderson
Volcanoes
are
very
interesting. They are formed
when magma breaks through
the crust. When lava flows
evenly, it forms a plateau like
shield. The ash eruptions can
produce small cinder cone
volcanoes. Volcanoes erupt
because magma is breaking
through the Earth's crust.
Volcanoes can be active,
dormant or extinct. An active
volcano that erupts in the
last few thousand years. A
dormant volcano means that
it has the potential to erupt
again, but hasn’t recently. An
extinct volcano is one that
has no potential to erupt
again.
Volcanoes most commonly
exist along or between
tectonic plates. About 90% of
volcanoes exists around the
ring of fire. The Ring of Fire is
located on the edge of the
Pacific
Ocean.
1,900
volcanoes are active around
the world. A lot of other
volcanoes are dormant, not
active. No volcanoes are
showing signs of exploding.
Some volcanoes can become
active in time.
Hot rock in a cold world
Brady Bartlett
When thick magma and large amounts
of gas build up under the surface,
eruptions can be explosive, expelling
lava, rocks and ash into the air. Less
gas and more viscous magma usually
mean a less dramatic eruption, often
causing
streams of lava to ooze from the
vent.A large eruption can be extremely
dangerous for people living near a
volcano. Flows of searing lava, which
can
reach 2,000 degrees Fahrenheit or
more, can be released, burning
everything in
its path, including whole towns.
Boulders of hardening lava can rain
down on
villages. Mud flows from rapidly
melting snow can strip mountains and
valleys
bare and bury towns while people are
living there. Scientists estimate that
more
than 260,000 people have died in the
past 250-300 years from volcanic
eruptions
and
their
aftermath.Although volcanoes are all
made from hot magma
reaching the surface of the Earth and
erupting, there are different kinds.
Shield
volcanoes have lava flows with low
viscosity that flow dozens of
kilometers; this
makes them very wide with smoothly
sloping flanks
When the Plates Move
Kendra Kremer
There are three layers of Earth, the core,
the mantel, and the crust. The core is the
center of Earth, it is mostly iron with
some nickel and it is very hot. The mantel
is the layer between the crust and the
core. It is 1,800 miles thick, mostly solid,
hard rock, but the top layer can be
flexible. The crust is the thinnest layer of
the Earth, it is about 5 miles thick below
the ocean, and 22 miles thick under the
land.
According to the Plate Tectonics theory
the crust and upper flexible layer of the
mantel is not one thick layer of rock, it is
actually 12 different moving plates. These
plates will push together in a process
called convection, move apart in a process
called divergent, or one tectonic plate will
slide under the other in a process know as
subduction. These processes cause land
forms to form. The Andes, Himalaya,
Alps, and the Rockies were formed from
processes like these. Islands such as Japan
or Aleution Island have been formed by
these processes too.
Due to tectonic plate movement the Ring
of Fire was created. This is a ring of
volcanoes around the pacific ocean.
Although earthquakes can happen
anywhere on earth the most earthquake
activity happens mostly in the Ring of
Fire. Most of the earthquake activity
happens hear because this is where many
of the tectonic plates meet. As the plates
move and bump into each other two plates
might get stuck together, but the two
plates will keep moving around. Once the
movement becomes too much the plates
will pull apart and cause an earthquake.
Weathering
Dalton Schmidt
Weathering is the wearing away or
change of the appearance or texture of an
object by long exposure to the air.There
are three main types of weathering,
physical, chemical, and biological.
In physical weathering rocks are broken
down into smaller pieces, but the
chemical composition stays the
same.Things that cause physical
weathering are temperature change,
freeze-thaw, wind rain, and waves.
Chemical weathering is when rocks are
broken down by chemical change. Acid
rain contributes to chemical weathering,
but mostly depends on the type of rock,
temperature, and the gases around the
rock.
Biological weathering takes place when
rocks are worn away by living organisms.
Trees and other plants can grow in the
cracks of rocks, and then over time the
roots break the rock apart.
Volcanoes will erupt
By: Jake Corbet
Volcanoes form when magma breaks
through the crust. Well when magma is on
the surface it's called lava. Volcanoes did
shape the Hawaiian islands. When the crust
breaks, folds or move a volcanoes can
form. The Ring of Fire is a bunch of
volcanoes surrounding the Pacific plate.
Volcanoes will form the land around them
when they erupt the lava will add on to the
crust.
Volcanoes can stay the same for century's
but change in seconds. Volcanoes have
many different forms like the shield
volcanoes, sratovolcano, cinder cone, lava
dome, caldera, lava plateau. Did you know

"Trees Today, Gone Tomorrow"
Small organisms like algae, moss, and
bacteria can grow on rocks, and produce
chemicals that break down rocks.
Small animals like mice, and rabbits can
burrow underneath rock, and that can
speed the formation of cracks in the rock.

What happens when trees are cut down? The loss of trees can
cause deforestation. Deforestation is the act of cutting down
trees in an area. Deforestation can have a tremendous effect
on humans and wildlife.
There are many reasons why deforestation occurs, but most
of the reasons relate to money or people's needs. The biggest
reason for deforestation is agriculture. Farmers cut down
trees to provide more room for planting crops. Often many
small farms will clear acres of trees by cutting down trees and
burning them in a process known as "slash and burn".
What are some of the solutions to deforestation. No longer
cutting down trees will help, but it won't do all of the work.
The trend in reforestation areas has been driven by
organizations such as the U.S. Forest Service
and the Arbor
Day Foundation.
Trees are valuable to wildlife and humans. Trees provide
homes for wildlife and give humans materials. As more trees
are cut down wildlife will have no homes and humans will.

you think about how crucial trees are to this world

How Erosion can create beautiful landforms on accident
There is Erosion by three main things water, wind, and glaciers. Water being the
major agent of erosion. Water movement has created the largest canyons, and
the deepest valleys. One thing that helps create these landforms are
sediments. Wind being the second major agent of erosion. It can be very bad
for famers, but it also creates loess. Glaciers being the third major agent of
erosion. Glaciers can create moraines. During, the Ice Age there were
continental glaciers. Those were the main causes of erosion.
Some of the greatest landforms were created by erosion. Baffin Island
Waterfall was created by mainly glaciers. Outer Banks Sandbars were driven by
ocean winds. Sand Tufa, wind removed the sand under the deposits. Erosion
creates many beautiful land forms my favorite ones are the waterfalls. Also
Arizona has amazing landforms like the rock formation they create the weirdest
shapes.

Why Farmers hate Erosion!!!
By: Brady Larson
Why do farmers hate erosion ?
Farmers hate erosion because
erosion brakes down their fields.
Erosion is the movement of soil
or sediments to another location.
From the help of weathering
which is the brake down of rock.
Erosion and weathering make the
perfect team by braking down
rock and moving it to another
location.
There is many types of erosion,
but the main two types are wind
and water erosion. Water erosion
is the most effective on higher
ground like hills. The water would
wash the soil from the top of the
hill to lower ground. On your farm
water erosion is the biggest
thing.
Tillage can prevent erosion or
advance erosion. No-till is the
best way to stop erosion, but
some places can't no-till. No-till
works better in sandy soils
because it dries out faster. The
depth and how many passes you
make with your chisel plow can
vary in many ways to. If you dig
to deep with your chisel plow you
could bring up more good soil to
be swept away.
Erosion is a big thing in our
country. We are always finding
Glaciers: The Sinker of the Unsinkable
By:Jon Haman
Glaciers, big blocks of moving ice to most. Some people may even
think of it has the thing that sunk the Titanic, but what a lot of people
don’t know is that glaciers shaped a lot of North America.
Glaciers cover 10% of land on Earth. They also hold 75% of the world’s
fresh water. From the 17th to 19th century the world experienced,
almost a mini ice age. Where the worlds temperature dropped which
created the giant blocks of ice now in the North and South Pole. If they
all melted the worlds ocean would rise about 70 meters. Glaciers often
appear blue when they are very dense. When they become extremely
dense, the ice absorbs a small amount of red light, leaving a bluish tint
in the reflected light which is what we see. When the glaciers are white
it mean it is filled with tiny air pockets.
The longest glacier in North America is the Bering Glacier in Alaska,
measuring 190 kilometers (118 miles) long. The Kutiah Glacier in
Pakistan holds the record for the fastest glacial surge. In 1953 it raced
12 km in three months, about 367ft per day. Each summer in
Washington State melting glaciers provide 470 billion gallons of water.
The largest glacier is Lambert-fisher Glacier in Antarctica. Which is
about 250 miles long, and 60 miles wide
All about glaciers
By:Briar Halberg
Did you know glaciers are a huge event of erosion? There
event of erosion because there huge slow moving sheets of
ice. A the glaciers move they carry stuff with them such as
rocks, soil, dirt ,and boulders. Did you know glaciers
sculpted the earth, and shape where we live today?
A glacier can't make itself unless it's above the snow
line.Glaciers normally in mountain areas. For some
examples are Sierra Nevada Mountains.
Did you know that there are different types of glaciers? I
actually did because I remember in some class in
elementary we had to study about glaciers. Alpine glacier is
a type of glacier. An alpine glacier is a glacier that forms by
mountains. Anther type of glacier is continental glacier,
witch is an on going mass of ice which is bigger than alpine
glacier.
When I think about glaciers I think about penguins and cold
and Igloos.This is what I learned about glaciers.

What You Should Know About Erosion
By: Brooke Aronson
Erosion is the process of moving sediment from one
location to another. The most important force of
erosion is gravity. The amount of erosion by a stream
depends on the velocity and volume of water flow.
Erosion happens when running water, sea waves,
wind, or glaciers pick up materials from the Earth's
surface and carry them to other locations. It removes
the topsoil first. Once this nutrient-rich layer is gone,
few plants will grow in the soil again.
Erosion is an important part of the cycle that has
made and kept the earth a place where living things
can survive. Without this process, the earth's surface
would be barren rock, with no soil where plants can
grow. Moving water such as rain, rivers, streams, and
oceans, is the greatest cause of erosion.
A time where erosion has appeared in my life was
when we planted grass at my lake. A week later, three
inches of rain fell and washed out the topsoil and the
grass seed. When it dried we had to put a fabric
barrier with straw inside it and that solved the
problem and the grass grew
Wild Volcanoes
By: Alexis Herda
I have never been anywhere out of North Dakota or Minnesota, so I
have never seen a volcano in real life. I have always wondered what
causes volcanoes, what makes volcanoes and what volcanoes do.
Did you know that the tallest volcano isn’t in our solar system, it’s on
Mars, its name is Olympus Mons, its elevation is 27km and it
measures 500 km across. The term volcano actually comes from
Vulcano, an Italian volcanic island, which was named after Vulcan,
the Roman god of fire. There are many volcanoes in a circular for and
it’s called The Ring of Fire. I have learned stuff about volcanoes from
reading about them, from school, and from my mom. Here’s an
interesting fact: Types of volcano rocks are basalt, rhyolite, andesites,
and plagioclase. The lava that comes out of volcanoes when they
explode is very, very, very, very hot. It destroys everything in its path. It
doesn’t really kill people, but it causes other things that do kill people,
like tsunamis, earthquakes, hurricanes, and other things. Fun fact:
The three major kinds of volcanoes are shield volcanoes,
stratovolcanoes, and cinder cone volcanoes. The worst volcano killed
92,000 people in Indonesia.
