What name is given to the science of classification?
- A.
Toxophily
- B.
Taxonomy
- C.
Taxidermy
- D.
Toxoplasma
Correct Answer
B. TaxonomyExplanation
Taxonomy is the science of classification, where organisms are grouped and categorized based on their characteristics and relationships. It involves organizing and naming species, creating hierarchical classifications, and establishing a system for identifying and classifying living organisms. Taxonomy plays a crucial role in understanding biodiversity, evolutionary relationships, and studying the natural world.Rate this question:

Which of these is not a weasel - or rather, which is not a member of the weasel's family, the Mustelidae?
- A.
Otter
- B.
Wolverine
- C.
Civet
- D.
Stoat
Correct Answer

The Apatosaurus is a genus of dinosaur formerly known as
- A.
Allosaurus
- B.
Brontosaurus
- C.
Camptosaurus
- D.
Diplodocus
Correct Answer
B. BrontosaurusExplanation
The correct answer is brontosaurus. The Apatosaurus is a genus of dinosaur that was formerly known as brontosaurus. In the late 19th century, two different dinosaur skeletons were discovered and named separately as Apatosaurus and Brontosaurus. However, further research revealed that these skeletons actually belonged to the same genus, and the name Apatosaurus took precedence. Therefore, the correct name for this genus is Apatosaurus, but it was once incorrectly referred to as Brontosaurus.Rate this question:

In the Linnaean system of classification, the animal kingdom can be divided into about 36 large groupings called phyla. How many different phyla would you be eating in a paella with the following ingredients: chicken, bacon, ham, langoustines, mussels, monkfish?
- A.
1 phylum
- B.
2 phyla
- C.
3 phyla

Most of Earth is reassuringly solid, but which layer is a liquid?
- A.
Inner core
- B.
Outer core
- C.
Inner mantle
- D.
Outer mantle
Correct Answer
B. Outer coreExplanation
The outer core is a layer of the Earth that is made up of liquid iron and nickel. It surrounds the solid inner core and is located between the inner core and the mantle. This layer is in a liquid state due to the high temperatures and pressures found deep within the Earth. The movement of the liquid outer core is responsible for generating the Earth's magnetic field through a process called the geodynamo.Rate this question:

The action of glaciers during past ice ages has given us many picturesquely craggy landscapes, but which of the following types of landform is not of glacial origin?
- A.
Ria
- B.
Esker
- C.
Corrie
- D.
Drumlin
Correct Answer
A. RiaExplanation
A ria is not of glacial origin. A ria is a type of coastal landform that is formed by the submergence of a river valley due to rising sea levels. It is characterized by a drowned river valley with steep sides and a flat bottom. Unlike other landforms mentioned, such as eskers, corries, and drumlins, which are all formed by glacial activity, a ria is formed by geological processes unrelated to glaciers.Rate this question:

Earth is pre-eminent among the planets of the solar system in terms of
- A.
Size
- B.
Density
- C.
Reflectivity
- D.
Magnetic field strength
Correct Answer
B. DensityExplanation
Earth is pre-eminent among the planets of the solar system in terms of density. Density refers to the mass of an object divided by its volume, and Earth has a higher density compared to other planets. This is due to its composition, which includes a solid core made of iron and nickel. The high density of Earth allows it to have a strong gravitational pull, which plays a crucial role in the planet's ability to support life and maintain its atmosphere.Rate this question:

In astronomy, seconds and hours can refer to angles as well as time. In those angular terms, one hour of right ascension contains how many seconds of arc?
- A.
240
- B.
3600
- C.
24,000
- D.
54,000
Correct Answer
D. 54,000Explanation
In astronomy, right ascension is a coordinate used to locate celestial objects in the sky. It is measured in hours, minutes, and seconds, similar to how time is measured. One hour of right ascension is equal to 15 degrees, and since there are 60 minutes in an hour and 60 seconds in a minute, there are 3600 seconds in one hour of right ascension. Therefore, the correct answer is 54,000 seconds.Rate this question:

- A.
To keep everything from happening at once
- B.
To make space more interesting
- C.
Of joining us with the big bang
- D.
Of spoiling your day
Correct Answer
A. To keep everything from happening at onceExplanation
The correct answer is "to keep everything from happening at once." This statement suggests that time acts as a mechanism to prevent all events from occurring simultaneously. Without the concept of time, all events would happen at the same instant, leading to chaos and confusion. Time allows for a sequential progression of events, creating order and structure in the universe.Rate this question:
