Chapter 32, Problem 3RAT

The nebular theory is based upon the observation that the solar system

(a) is highly ordered, indicating it formed in a stepwise manner from physical processes.

(b) has a structure much like an atom.

(c) is highly complex and appears to have been built by chaotic processes.

(d) appears to be very old.

To determine

The correct option for the statement “The nebular theory is based upon the observation that the solar system”

Answer to Problem 3RAT

The correct option for the statement “The nebular theory is based upon the observation that the solar system” is option (a).

Explanation of Solution

The nebular theory gives an explanation of how our solar system formed. The theory that explains the solar system formation must be able to explain the following points:

(i) The orderly motion among the bodies of our solar system.

(ii) The division of planets into two main types- terrestrial and Jovian.

The modern theory that meets these requirements is called nebular theory.

According to this theory, our solar system began to condense from a cloud of gas as well as dust. The cloud would have been diffuse with diameter thousands of times greater than Neptune’s orbit. The physical gravitational pull and diffusion of clouds are responsible for the formation of our solar system.

Conclusion:

Therefore, the correct option for the statement “The nebular theory is based upon the observation that the solar system” is option (a).
