Question

Which of these diagrams best represents the steps in the formation of planets? a.) the sun is born, clouds rotate at high speeds, the clouds flatten into an elliptical disc, the planets are born.

b.) the clouds flatten into an elliptical disc, the sun is born, the clouds condense, the planets are born

c.) the clouds of dusts and gases rotate at high speeds, the clouds condense, the sun is born, the planets are born

d.) the clouds of gases condense, the clouds rotate at high speeds, the clouds flatten into an elliptical disc, the planets are born

Answer 1

b.) the clouds flatten into an elliptical disc, the sun is born, the clouds condense, the planets are born

:)

Answer 2

Answer: d.) the clouds of gases condense, the clouds rotate at high speeds, the clouds flatten into an elliptical disc, the planets are born

Explanation:    

Planets are formed from proto-planetary disk.

• In the molecular cloud of dust and gases, a core is formed as the cloud condenses under its own gravity.
• The cloud starts spinning at high speed gathering more and more mass. At the core, the temperature and pressure rises eventually startling a nuclear fusion process and a star is formed.
• The rest of the material flattens into a proto-planetary elliptical disc from where planets are born.

Thus, the correct order is: d.) the clouds of gases condense, the clouds rotate at high speeds, the clouds flatten into an elliptical disc, the planets are born
