Geology Trivia Questions

1. The molten rock that sits below the earth's surface is called what?

From Quiz
Taken for Granite

Answer: Magma

Magma is generally formed via the partial melting of the Earth's crust and the upper mantle (athenosphere). The temperature range of magma is 700 - 1300 degrees Celsius, depending on its composition. Mafic magmas (high iron and magnesium) have a much higher temperature than felsic magmas (high silica).

2. How many different space lattices are there?

From Quiz Crazy Crystal Structures

Answer: 14

Yes there are 14 different space lattices (organized in seven systems) that could be formed. A space lattice is a small primitive cell that can be repeated potentially an infinite amount of times to form the macro crystal structure. In a space lattice there are three dimensions and four angles to be considered. Each space lattice will have three corners. See if you can guess all the possible combinations.

3. Diamonds rank at number 10 on the Mohs scale, meaning they are the hardest mineral listed. Where would cubic zirconia (CZ) rank on the scale?

From Quiz Cubic Zirconia Is A Girl's Best Friend

Answer: 8-8.5

This means that a CZ has a greater hardness than most semi-precious natural gems. On the Mohs scale, corundum ranks 9 and diamond ranks 10.

4. Corporal Slag was pleased that he was able to identify the volcanic rock rhyolite. Which other igneous rock shares the same chemical composition as rhyolite?

From Quiz Random Ramblings of a Rockhound

Answer: Granite

Rhyolite is an extrusive igneous rock formed by the rapid cooling of lava on the earth's surface. When the same lava (known as magma when found within the earth) cools and forms rocks within the earth's crust, it forms granite. Both rocks have a higher amount of silica and lesser amount of iron and magnesium.

5. The emerald is a type of beryl. The distinctive green color of the emerald derives from trace amounts of what metallic elements?

From Quiz Elementary Minerals

Answer: chromium and vanadium

The name emerald comes from the Latin esmaralda, derived from the Hebrew izmergad meaning green. The Hooker brooch at the National Museum of Natural History is a 75 square-cut emerald surrounded by diamonds.

6. Follow my long axis, and I point the way the glacier moved.

From Quiz What Geologic Feature am I?

Answer: Drumlin

Made of glacial deposits, or till, the drumlin is elongated in the direction that the glacier flowed.

7. Why did miners coin the phrase "hanging wall?"

From Quiz The Lithosphere...

Answer: One could hang a lamp on a hanging wall while they're mining.

The terms footwall and hanging wall were coined by miners because one could hang a lamp on a hanging wall and stand on a footwall.

8. The name given to a region in which limestone formations dominate the scenery and topography is karst. In what country is the region that gives us this name?

From Quiz The Limestone Landscape

Answer: Slovenia

The Kras limestone plateau is on the Istrian Peninsula, east of Trieste. The word "karst" comes from the German name for the area. More generally, karst can mean any rock formation which has lost more of its material through dissolution rather than erosion. Most karst formations are limestone and most limestone formations are karst.

9. The mineral phenakite is named after a Greek word that translates to what phrase in English?

From Quiz Interesting Mineral Facts

Answer: to deceive

Phenakite is named from a Greek word for "to deceive" because it was long confused with quartz and other minerals that appear similar. A British specimen, pictured in an 1811 work, was described as white tourmaline for twenty years before it was recognized as a new mineral.

10. What common, pale yellow, metallic mineral has a greenish black streak and is used as a source of the mineral sulfur?

From Quiz Rocks and Minerals

Answer: Pyrite

A unique crystal type called 'pyritohedron' is named after this mineral.

11. Caused when overlying material is removed and intrusive igneous rock expands.

From Quiz Geology 101: Weathering

Answer: Pressure-release fracturing

12. 99 percent of this soil horizon is made of organic material.

From Quiz Geology 101: Soil Horizons

Answer: O

The layers are labeled O, A, B and C, with D being bedrock. The top layer consists primarily of dead plant material. As far as I can ascertain, the letters do not stand for any specific word.

13. Speed and direction of stream flow.

From Quiz Geology 101: Streams

Answer: Velocity

14. Which sedimentary rock reacts with hydrochloric acid?

From Quiz Taken for Granite

Answer: Limestone

The White Cliffs of Dover are made of chalk - a type of limestone. This limestone is composed dominantly of coccoliths (phytoplankton with calcium carbonate 'shells') and was formed during the Cretaceous Period (145 million years ago - 65 million years ago).

15. In the tetragonal crystal structure such as that seen in the neodymium-iron-boron magnet, all angles are 90 degrees. But what are the sides like?

From Quiz Crazy Crystal Structures

Answer: Two axes are the same, one different.

The tetragonal crystal structure is one that looks like a 3D rectangle with all angles at 90 and two pairs of different lengths. It makes up 2 of 14 space lattices. These are the simple tetragonal and the body centered tetragonal.

16. Cubic zirconia has a refractive index of 2.15-2.18. What does refractive index refer to?

From Quiz Cubic Zirconia Is A Girl's Best Friend

Answer: dispersion of light

Think of when you turn a diamond or a CZ to the light and a rainbow of colors appears. The white light is being split into all those colors. The refractive index of diamond is higher at around 2.4.

17. Some granites were enjoying life when an earthquake occurred and buried them underground. Centuries later, they were brought up. One saw his reflection in the river and was shocked. What had he become?

From Quiz What Have I Become?

Answer: Gneiss

They were to be known as gneiss henceforth. Gneiss is a common metamorphic rock formed by regional metamorphism (involving large areas) of igneous rocks, commonly granite. Rock salt is a chemically formed metamorphic rock formed by evaporation of waters in Dead Sea and Aral Sea, among others. Mica is a common rock forming mineral.

18. At the emerald mines of Muzo in Colombia, I learnt that emeralds are a form of the mineral beryl and the green colour is attributed to traces of chromium or vanadium. What special pattern do the rare trapiche emeralds of Colombia contain?

From Quiz Land Down Under

Answer: Star

The trapiche emeralds are a rare type that are found only in three mines in Colombia - Muzo, PeƱas Blancas and Coscuez, all three of which are located along the Carera river. The stones contain carbon impurities that radiate outwards from a central core forming a six pointed star. Other regions famous for emeralds include Pakistan, Zimbabwe and Russia. Another gemstone from the beryl family is the aquamarine which is a blue variety of beryl. The blue colour is due to the presence of iron in the stone.

19. Who is considered to be the Father of Modern Geology, whose work, among other things, created the basis of the theory of Uniformitarianism?

From Quiz Physical Geology

Answer: James Hutton

Uniformitarianism is the theory that the Earth's processes are unchanging over time and progressing at very slow rates. So basically, according to this theory, the natural processes that shaped our Earth millions of years ago are the same as the natural processes that are still shaping our Earth today.

20. Turquoise was mentioned in the introduction. Its characteristic blue or green color comes from the combination of a metallic element with aluminum and oxygen. What is this metallic element?

From Quiz Elementary Minerals

Answer: copper

Fabulous turquoise jewelry has been crafted by the Dine' (Navajo), Zuni, and other Native American groups. Before the current groups of Native Americans living in the Southwest, the Hohokam (disappeared in the fourteenth century) of the Tucson Basin produced ornaments with turquoise mosaic on shells.

21. A prominent form of limestone weathering is the dissolution of limestone by acids. What is the acid primarily responsible for this?

From Quiz The Limestone Landscape

Answer: Carbonic acid

Carbonic acid is a very weak acid which forms when rain water reacts with carbon dioxide in the atmosphere. It is, however, strong enough to dissolve limestone to form calcium bicarbonate, a cause of "hard water".

22. Crystals are usually recognized by their natural flat surfaces called _______.

From Quiz Clearly Crystals

Answer: faces

Faceting is the process of cutting a gem stone to reveal the full beauty of transparent minerals.

23. What causes the red color in the mineral corundum?

From Quiz Interesting Mineral Facts

Answer: metal oxides

Pure corundum is clear in color. The gem colors of corundum are a result of minor metal oxide impurities; ruby is colored by chromium oxide.

24. Which native element, noted for its high specific gravity and metallic luster, is noted for its yellow color?

From Quiz Rocks and Minerals

Answer: Gold

Gold is found in a variety of different forms, including nuggets, leaves, and even crystals.
