Question 2 of 10

2. Another style of rock formation is a tea table, where an area of rock is less eroded on top than it is on the bottom, creating a small tower with a wide top and narrow base. Which US National Forest is most famous for these? Hint

Caribou-Targhee

Gifford Pinchot

Inyo

Shawnee

Cathedral Rock

Question 6 of 10

6. Half Dome, a mountain in Yosemite National Park, is a huge granite formation which rises nearly 5,000 feet above the valley floor. The local Native Americans originally called it this name, meaning "Cleft Rock". Hint

Ahwiyah

Orboron

Tis-sa-ack

Mesa Forma

Question 7 of 10

7. Petrified wood, which occurs when all organic materials in a plant are replaced by minerals, is actually a rock, and can become a variety of colors based on what minerals compose it. Which of these color/mineral combinations is incorrect? Hint

Iron-Purple

Copper-Green/Blue

Manganese-Pink/Orange

Carbon-Black

NEXT>

Question 8 of 10

8. Karst topography is a form of geological erosion in which bedrock is melted out by acidic water, creating, in some cases, hundreds of small caverns through which water can flow. The unusual name for this kind of formation comes from the German pronunciation of which Slovenian area famous for them? Hint

Kers

Kras

Krast

Kraes

NEXT>

Question 9 of 10

9. Mesas and buttes can often be confused with each other, though they are quite different. How so? Hint

Buttes have very steep, often vertical sides and are smaller than mesas

Buttes are always made of much softer rock and as such erode faster than mesas

Mesas are much smaller than buttes and must be below 1000 feet tall

Mesas tend to be uninhabited and require special permits to be built upon

Question 10 of 10

10. Occasionally, when seismic activity occurs in glacial areas, a lava eruption will break through an ice sheet and form a steep, flat-topped volcano. What is the name of this formation? Hint

Tahltan

Table

Hogg

Tuya

Quiz Answer Key and Fun Facts

1. Firstly, what is a hoodoo in geographic terms?

Answer: A natural rock spire caused by erosion

Also called tent rocks, fairy chimneys, and earth pyramids, these towers are coated with a layer of less-erodible rock with softer rock underneath. This allows the spire to survive in wet conditions without eroding.

Answer: Shawnee

Shawnee National Forest also contains Hicks Dome, which is argued to either be a volcanic hot spot or a meteorite impact zone. It also is the home of Little Grand Canyon, a 200 foot deep chasm with the Big Muddy River at the bottom. Shawnee was originally under a large glacier, and the meltwater during the glacial retreat carved this canyon.

3. This formation is somewhat like a rocky outcropping which rises free-standing from a smooth hill.

Answer: Tor

These are primarily made from granite or similar metamorphic rocks, but also could be made of quartzite or volcanic rocks. How they are formed though, is not quite understood yet, but there is a theory that material surrounding the harder mineral is worn away by natural means, allowing the tor to rise out of the surrounding rock.

4. Uluru, or Ayers Rock, in Australia is a large red rock structure made of which of the following materials?

Answer: Sandstone

Uluru is a word originating from the local Aboriginal language of Pitjantjatjara, but does not hold any further meaning. The dual naming of the rock was certified on December 15, 1993, and Uluru became the primary dual name on November 6, 2002.

5. On the topic of red rock, Sedona, Arizona is home to some of the best known red rocks in America. Which of these is not the name of one of the famous rock structures in Sedona?

Answer: Sunrise Rock

Built into one of the large formations is the Chapel of the Holy Cross, created by one of Frank Lloyd Wright's students, Richard Hein. It was finished in 1956, and in 2007 was added to the Seven Man-Made Wonders of Arizona.

Answer: Tis-sa-ack

Other famous formations in Yosemite include El Capitan, the largest granite monolith in the world, and Glacier Point, which is covered in snow for most of the year.

Answer: Iron-Purple

Artificial petrified wood has been created in labs where wood is soaked in an acid solution and then a silica solution, and finally heated in an argon atmosphere. Petrified wood, due to the time it takes for it to form naturally, can cost upwards of $1600 for a large log.

Answer: Kras

The most typical acid in the water that can erode bedrock is carbonic acid, but the rock can also erode through sulfide oxidization, which has occurred in caves such as Lechuguilla Cave in New Mexico.

9. Mesas and buttes can often be confused with each other, though they are quite different. How so?

Answer: Buttes have very steep, often vertical sides and are smaller than mesas

Buttes are often vertical, craggy towers jutting out of the ground. Their name comes from French meaning "small hill". Geographers tend to say that a butte is classified as such if its top is narrower than its height, whereas a mesa has a wider top.

10. Occasionally, when seismic activity occurs in glacial areas, a lava eruption will break through an ice sheet and form a steep, flat-topped volcano. What is the name of this formation?

Answer: Tuya

This occurrence is quite rare. The name is derived from the surrounding Tuya ranges in British Columbia where Bill Matthews studied the first one. The word is believed to be from the local native language of Tahltan.
