Question

What are the three examples of how the nebular theory explains some observed features of the present-day solar system?

Answer 1

Hint: We need to understand what the theory of nebulas tells in order to explain the features of the solar system that are explained by the nebular theory of the universe. This can be used to solve the given problem which explains these features.

Complete Solution:
The Nebular theory or the hypothesis is the best-known explanation on the formation of the solar system. It says that the solar system was primarily a large cloud of dust and gas known as nebulae. This nebula is believed to be formed as a leftover of an old dead star which was a supernova.

The Nebula gradually started to collapse due to the strong electromagnetic forces of the ionized gases and started forming masses which developed gravitational force between these masses.

The Nebular theory says that the central mass which experienced the maximum forces formed the biggest mass forming a protostar which is the sun of the solar system.

The nebular theory also states that the nebula was rotating the entire time which resulted in the rotation of the planets in the solar system.

Also, the theory explains that due to the rotation of the nebula, the lighter materials got far apart as an effect of getting thrown, which is true in the present-day solar system which constitutes the exo-planets and the frozen gases.

These are the few features which go in tie with the nebular theory about the formation of the solar system.

This is the required solution.

Note:
The Nebular theory was a philosophical theory which later on could bring in many aspects of the solar system which were true. But there are numerous conclusions from the theory which do not go in hand with the empirical observations of the system.
