What is the current scientific thinking about the formation of the solar system?

A. Differences in the rate of radioactive decay of different elements caused planets of different sizes and unique properties to be formed from the dust and gas particles in the area of the universe that became the solar system.

B. During the big bang, fusion reactions created a large number of new elements and other matter that formed the objects in the solar system. When all the objects were formed that the solar system could accommodate, the fusion reactions stopped.


C. The solar system formed as a result of a series of supernova events. Elements scattered by these events recombined to form the sun, the planets, moons, and all other celestial bodies found in today's solar system.


D. The solar system formed from the dust and gases in a nebula. A center bulge in the nebula became the sun. The area of flat rings in the nebula became the individual orbital paths in which the planets revolve around the sun in the plane of the ring the path came from. Dust and gas particles found in each area combined to form the planets and their moons.

Respuesta :

The solar system formed dust and many gases in a nebula. The center of the nebula eventually became the sun. The flat rings of outside the nebula became the orbit paths, and that is where the planets stay and rotate around the sun. After that dust particles and gases that were found were all combined up to create planets and moons. so its D

Answer:

D. The solar system formed from the dust and gases in a nebula. A center bulge in the nebula became the sun. The area of flat rings in the nebula became the individual orbital paths in which the planets revolve around the sun in the plane of the ring the path came from. Dust and gas particles found in each area combined to form the planets and their moons.

Explanation:

Stars are born in molecular clouds known as nebula.

According to current most believed theory, solar system was born in solar nebula. It is composed of dust and gases. This cloud of dust and gases collapsed under its own weight and condensed to form the core. It started spiralling and gathering more mass till temperature rose to start the nuclear fusion reaction and the sun was born. The rest of the matter accreted to form planets and their moons. The planets orbit the sun in elliptical paths.

Thus, options D is correct.
