Theoretical astronomy is a lecture and an article. It is part of the astronomy course on the principles of radiation astronomy.

You are free to take this quiz based on theoretical astronomy at any time.

To improve your scores, read and study the lecture, the links contained within, listed under See also, External links, and in the {{principles of radiation astronomy}} template.

This should give you adequate background to get 100 %.

As a "learning by doing" resource, this quiz helps you to assess your knowledge and understanding of the information, and it is a quiz you may take over and over as a learning resource to improve your knowledge, understanding, test-taking skills, and your score.

Quiz[edit | edit source]


1 Yes or No, A theory is a statement of how and why particular facts are related.


2 Astronomy is not purely theoretical because of which phenomena?

the Sun
displacements consist of a number plus a dimension such as kilometers
a late-summer rainstorm

3 True or False, The expanse of space that seems to be over the Earth like a dome is called heaven.


4 An entity is an independent, separate, or self-contained


5 True or False, Definitions are part of theory because words are part of explanations.


6 An astronomical theory with no mathematics attached may be which of the following?

an existence
the Sun
a meteorite impact
a late-summer rainstorm
the Moon

7 Evidence that demonstrates that a model or idea versus a control group is feasible in theoretical astronomy is called a


8 True or False, A phenomenon is an observable fact or event.


9 Which of the following is not an idea?

the Sun

10 True or False, A control group may be used in theoretical astronomy to demonstrate no effect or a standard effect versus a novel effort applied to a treatment group.


11 Complete the text:

Match up the theoretical astronomy idea with each of the possibilities below:
astronomical object - A
astronomical source - B
astronomical entity - C
star - D
interstellar medium - E
material - F
natural luminous body visible in the sky

naturally from which something comes

matter which may be shaped or manipulated

an independent, separate, or self-contained existence

the matter that exists in the space between the star systems

naturally in the sky especially at night


12 If astronomy measures distances and speeds then what is mass?

an idea
a number
many distances
the sky
an orbit

13 True or False, The purpose of a treatment group in theoretical astronomy is to describe natural processes or phenomena for the first time relative to a control group.


Hypotheses[edit | edit source]
