Question

Which of these is NOT evidence we must consider for the Nebular Theory?

a. The two major belts of the solar system (i.e., structure).

b. Most planets rotate counter-clockwise

c. The number of planets with atmospheres.

d. All planets lie close to the ecliptic plane.

Answer 1

In the context of the Nebular Theory, the number of planets with atmospheres is NOT evidence we must consider, as atmospheric presence is influenced by factors other than the solar system's formation process.

Step-by-step explanation:

The evidence we must consider for the Nebular Theory generally includes the inherent motions and arrangements of celestial bodies within our solar system that suggest they formed from a common rotating cloud of gas and dust. Specifically, the options given:

• The two major belts of the solar system (i.e., the structure)
• Most planets rotate counter-clockwise
• All planets lie close to the ecliptic plane

are in alignment with the

Nebular Theory

. These observed patterns of motion and alignment with the ecliptic plane support the idea that the solar system formed from a spinning solar nebula. The

number of planets with atmospheres

, however, is not directly relevant to the evidence for the Nebular Theory because an atmosphere's presence or absence can be influenced by many factors other than the formation process of the solar system. Therefore, the correct answer is that the number of planets with atmospheres is NOT evidence we must consider for the Nebular Theory.
