Heliogony is a lecture and an article focusing on the origin of the Sun. It is a lecture as part of the astronomy course on solar astronomy.

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

To improve your score, read and study the lecture, the links contained within, listed under See also, and in the course 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.

A suggestion is to have the lecture available in a separate window.

To master the information and use only your memory while taking the quiz, try rewriting the information from more familiar points of view, or be creative with association.

Enjoy learning by doing!

Quiz

Point added for a correct answer:   
Points for a wrong answer:
Ignore the questions' coefficients:

1. True or False, The Sun is the third most abundant entity in the solar system.

TRUE
FALSE

2. Complete the text:

Cosmogony is a term which admits some or, at least, .

3. True or False, As Jupiter's orbit is not in the plane of the Sun's equator, Jupiter may have formed elsewhere.

TRUE
FALSE

4. What effects does the distribution of angular momentum in the solar system have on the origin of the Sun?

an initially spherical and contracting nebula spinning faster as it collapses would produce the present situation in the solar system
partitioning mass and angular momentum does not seem possible with a contracting nebula
the rotation axis of the Sun from that of the system as a whole if formed by nebular collapse seems very unlikely
the angular-momentum problem does not arise with the accretion theory
surface differential rotation of the Sun results
by the nature of the floccule process the star so formed will have little angular momentum

5. Complete the text:

Match up the structure of the proto-Sun with the heliogonic characteristic or property:
radiative zone - L
core - M
convection zone - N
dynamo - O
tachocline - P
photosphere - Q
atmosphere - R
temperature region - S
chromosphere - T
transition region - U
corona - V
heliosphere - W
apparent outer surface .
just above the radiative zone .
top of the radiative zone .
part of the heliosphere .
below the corona and above the photosphere .
below the protostar's radiative zone .
coolest layer in the protoplanetary disc .
shear between different parts of the Sun that rotate in the radiative zone .
above the photosphere .
transition from almost uniform to differential between radiative and convective zones .
probably not differentiated as a protostar .
between the protoplanetary disc and the heliosphere .

Research

Hypothesis:

  1. Questions regarding the origin of the Sun should also address star-forming regions along the Sun's galactic orbit.

Control groups

The findings demonstrate a statistically systematic change from the status quo or the control group.

“In the design of experiments, treatments [or special properties or characteristics] are applied to [or observed in] experimental units in the treatment group(s).[1] In comparative experiments, members of the complementary group, the control group, receive either no treatment or a standard treatment.[2]"[3]

Proof of concept

Def. a “short and/or incomplete realization of a certain method or idea to demonstrate its feasibility"[4] is called a proof of concept.

Def. evidence that demonstrates that a concept is possible is called proof of concept.

The proof-of-concept structure consists of

  1. background,
  2. procedures,
  3. findings, and
  4. interpretation.[5]
