Question

The nebular theory is the most widely accepted view of the origin of our solar system. Which of the following is a short description of the nebular theory?
A) Thermonuclear fusion created the rotating rings of debris in our solar system.B) Hydrogen and helium were formed from expansion approximately 13.7 billion years ago to create our solar system.C) High heat and pressure led to the formation of magma bodies, which cooled, condensed, and formed the objects in our solar system.D) A large cloud of space gas and dust condensed and contracted to form a rotating disk with a star formed at the center. Repeated collisions caused bodies to coalesce, leading to the current configuration of our solar system.E) Radiation of energy from a catastrophic explosion created a disk-shaped mass of gas and dust.

Answer 1

Answer:

D.

Explanation:

The Nebula Hypothesis is the most widely accepted to explain our solar system formation. According to the theory, the Sun and planets were formed from a giant cloud (nebula means cloud in latin) which contained gas and dust.

Then, some gravitational event help to collapse the center. With this event, began to form denser regions, which, as result, attracted more and more matter, the region with more concentration create the Sun and surroundings of matter create planets and other components of the Solar System.
