The Dead Sea Rift Valley

By: Kyle Gurka & Jacob Pyle

1. East of the Rift Valley are two ancient lava fields.

2. It  is the lowest point on Earth.

 3. The water around the Rift Valley has so much salt, you can lay on your

back and float on the water.

The Dead Sea Rift Valley was formed when the Arabian Tectonic plates moved northward, then eastward away from Africa.

Mt.Vesuvius

Facts about Mt.Vesuvius 

Mount Vesuvius is best known for its eruption in AD 79 that led to the destruction of the Roman cities of Pompeii and Herculaneum and the death of 10,000 to 25,000 people. It has erupted many times since and is today regarded as one of the most dangerous volcanoes in the world because of the population of 3,000,000 people living nearby and its tendency towards explosive eruptions.

Formation of Mt.Vesuvius Vesuvius was formed as a result of the collision of two tectonic plates. One plate was pushed beneath the other.  The crust material became heated until it melted, forming liquid rock called magma.

Because magma is less dense than the solid rock around it, it was pushed upward. Finding a weak place at the Earth's surface it broke through, producing the volcano.

The Great Blue Hole

by Andrew Trostle and Carmen Maynard

                     How It Was Formed. . .

The Great Blue Hole is a sinkhole 100 kilometers from Belize City. It was formed by a limestone cave system.

Facts About The Great Blue Hole

The Great Blue Hole was made famous by Jaques Cousteau.

 It is amazingly 410 feet deep. It was voted one of the seven natural wonders of the world.

Mendenhall Glacier

By:Daniel Blanchard

Mendenhall Glacier

Originally known as Sitaantaagu ("The glacier behind the town"). The glacier is 12 miles long & has retreated(melted) 2.5 miles since 1700. It is located in Alaska.

FormationGlaciers are formed when ice builds up over time and the weight compresses itself into ice.Then the glacier slides down hills with less then 30 degrees slant. If it slanted any more the glacier would avalanche.

Mauna Loa Volcano

By: Celine Munyana

Quick Facts:1.The Mauna Loa volcano is the world's largest volcano! It takes up 50.5% of Hawaii.

2.Mauna Loa's first eruption was in 1794 and its last was in 1984.It has erupted 39 times. 3.The Mauna Loa volcano is also 4,170 meters above sea level. 

  How The Mauna Loa Volcano Was Formed 

The Mauna Loa Volcano is formed by pressure building up below the Earth’s crust. Magma forces it way through weaknesses in the earth's crust. When the magma emerges it is called lava. When it cools, it solidifies into rock,or it may emerge though thin cracks,which are called fissure.Or it may be forced though wider pipes,that starts to build up, to a volcano.

Royal GorgeBy: Olivia R. and Kendall C.

Did You Know That .....

The Royal Gorge is a ten mile long canyon in Canon City, Colorado.The gorge was formed when the Arkansas River cut through. It took millions of years to cut through the rock, so the gorge is very old.The Gorge was discovered in1806 by U.S. explorer Zebulon Pike.

The gorge has a bridge going over it that many people go to drive over. There is also an amusement park built directly above the gorge.You can even go rafting down the Colorado River straight through the canyon.

So, how was it formed?Geologists have mixed thoughts on how the gorge was formed, but the general consensus is that it was formed by the force of the mighty Arkansas River, churning and pounding against the rock for millions of years.This is called erosion. About three million years ago, as the Rocky Mountains rose from the surrounding plains a small rivulet that would become the Arkansas River rose with them.

SAHARA DESERT

BY:MALLORY MCCULLEY

:an intense dust storm sent a dustplume northwestward over the Atlantic ocean on March 2, 2000 :the Sahara Desert covers more than 3,500,000 sq.mi.

:some sand dunes reach 180 m. high

Chicxulub Crater

Dinosaur Murdererby

Timmy Vanek

 

 

Chicxulub Crater ....is all but hidden in the flat limestone of Mexico's Yucatan Peninsula.The Chicxulub Crater is 112-miles  wide, 3,000 foot deep impact crater.

The Forming of Chicxulub Crater It is a theory that the Chicxulub Crater was formed by the meteorite that caused the extinction of the dinosaurs.

An impact crater is formed when an asteroid, meteorite or comet crashes into the Earth or other planet.

Bay of Fundy

By Bailey Kenjura &Hannah Buls 

Interesting Facts!

This is a picture of the Bay of Fundy's high tides. Did you know that this bay has the highest tides in the world? As the tides rush up the narrowing funnel-shaped bay, high crested waves rise to 52 feet. This  is a picture of the bay when it has low tides.This bay has the largest concentration of whales and sea life.

How Was it Formed?

How the Bay of Fundy was formed was by the continental  plates of Africa and North America parting millions of years ago, forming the Atlantic Ocean. Over time as vast mountain ranges collided and then slowly separated, huge rift valleys were created.

San Andreas Fault

by Nick Summerour 

San Andreas Fault Facts1.The San Andreas Fault is the sliding boundary between the Pacific Plate and Northern American Plate. 2.The Northern segment of the San Andreas Fault extends from Shelter Cove to South of the Francisco Bay area. 3.There are many myths and legends about the San Andreas Fault, the biggest being that it will one day crack and California will sink into the sea. Wrong!

San Andreas Fault FormationThe San Andreas Fault is a large crack in the Earth's crust that moves sideways rather than up and down as is more common. Most of these types of faults occur in the sea, but those that occur on land should be considered dangerous.The San Andreas Fault began forming about 20 million years ago with a change in its plate's positioning. Over the years, its plate is collapsing under the plate beneath California. As that happens, the San Andreas Fault will continue to grow, perhaps twice today's length. Pictures provided by:Wikipedia.Information provided by:About.com and Geology.com.Thank you!!!!

Hawaiian Islandsby: Sally C. and Evan B.

 

1.The Hawaiian Islands are home to the sparrow-sized songbird found nowhere else in the world!

 2.Hawaii has lots of volcanoes on it because

volcanoes created the beautiful Hawaiian Islands. 

3.Barack Obama was born in Honolulu, Hawaii.

!Cape Dorset and Cape Cod! 

CONGRATULATIONS!You've just won a trip

to lovely...

BY:Julie Wegner and Carlie English!            

Here's some facts to get you started!

             Cape Dorset                             Since the 1950's, Cape Dorset, which calls itself the capital of inuit art, has been a center of drawing, printmaking, and carving.A cape is a strip of land projecting into a body of water.record high-   77 degrees Frecord low-   -45degrees F

                   Cape Cod    Cape Cod is often referred to as simply the Cape, and called the Cape of Keel by early Norse explorers.The Pamet Valley in Truro, is wider and deeper than all other valleys on Cape Cod.

Cape Cod was formed as the terminal moraine of a glacier,resulting in a peninsula in the

         Atlantic Ocean.                                                               

            How was it formed?

Sorry,you really didn't win a trip,but you learned a lot about Cape Dorset and Cape Cod! We will give you a free bag of Cape Cod Potato Chips! Well, I hope you enjoyed it. Bye!

There are many different kinds of Cape Cod Potato Chips. I got some at the gas station! They are very good. Try some!

  !HI!

DID YOU KNOW??

• The number of people that have tried to climb Mount Everest approximately:4,000 and the total number that have successfully climbed Mount Everest:660

• Mount Everest is as tall as 20 empire state buildings and it is still growing

• Scientists think Mount Everest is about 60 million years old

It was formed by…..

The continent of India is part of a plate that "crashed" into southwest Asia, but it didn't stop when it hit. It continued to push northward, crushing and rumpling the earth's crust, resulting in the mountains we see today. If you look at a map of the Himalayas, you can see that the mountains look kind of like a rumpled blanket. India is still pushing northward today, raising the Himalayas even higher!

MISSISSIPPI RIVER DELTA  

ByTori Bosse

Amazing facts about the Mississippi River Delta

-The river and its delta have been changed dramatically by humans and we are just now seeing it.         -The river is dropping by up to 5-1cm each year...

How was the Mississippi River Delta formed????

-Since the beginning the Mississippi River Delta has been uplifted by as much as 40ft. -The sea level has lowered by about 450ft. -The faults close by are also a big reason

COLCA CANYON

by: Troy Freeman

Fun fact - did you know that the name Colca refers  to theholes in the canyon, people used to store food in them.

Colca Canyon

The sides of the Colca Canyon are not vertical like the  Grand Canyon.

Colca Canyon

It was formed by millions of years of water breaking away from the canyon.
