Questions and Answers

1.

The word "astronomy" comes from the Greek word...
- A.
  
  Astron
- B.
  
  Astronomer
- C.
  
  Astoma
- D.
  
  Aston
Correct Answer
A. Astron

Explanation
The word "astronomy" comes from the Greek word "astron," which means "star." This is evident in the root of the word, "astro," which is commonly associated with celestial objects such as stars. The suffix "-nomy" refers to the study or science of a particular subject, thus combining "astro" and "-nomy" gives us "astronomy," the study of stars and other celestial bodies.

Astronomy is a study of everything of the atmosphere of...
- A.
  
  Earth
- B.
  
  Mercury
- C.
  
  Mars
- D.
  
  Jupiter
Correct Answer
A. Earth

Explanation
Astronomy is the study of celestial objects, such as stars, planets, and galaxies, as well as the phenomena that occur outside Earth's atmosphere. Since the question asks for the study of everything in the atmosphere, the correct answer is Earth. Earth's atmosphere is extensively studied in astronomy to understand weather patterns, climate change, and the composition of gases that make life possible on our planet.

Which of these is best described as astronomy?
- A.
  
  Natural science
- B.
  
  Earth science
- C.
  
  Geography
- D.
  
  Geology
Correct Answer
A. Natural science

Explanation
Astronomy is best described as a natural science because it is a branch of science that deals with the study of celestial objects, such as stars, planets, galaxies, and other phenomena that occur outside of Earth's atmosphere. It involves the observation, analysis, and interpretation of these celestial objects and their interactions. Astronomy also encompasses the study of the universe's origins, evolution, and the physical laws that govern it. Therefore, it falls under the category of natural science, which focuses on the study of the natural world and the laws that govern it.

What did the Ancient Greeks try to explain by taking measurements?
- A.
  
  The motion of the sun and stars
- B.
  
  The movement of the planets
- C.
  
  The movement of the sun
- D.
  
  The motion of moon and sun
Correct Answer
A. The motion of the sun and stars

Explanation
