Solar System formation

The video explains the formation of the solar system, starting with a massive cloud of hydrogen and cosmic dust that collapsed under its own gravity. This led to the creation of a massive sphere surrounded by a rotating disk of gas and dust. Over millions of years, matter in the disk consolidated, and when the central sphere reached a million degrees, nuclear fusion was ignited, marking the birth of the Sun and its planets.

What initiated the formation of the Sun and its planets?

• A massive explosion

• Condensation of a hydrogen and cosmic dust cloud

• Collision of two stars

• A supernova event

What was formed as the immense cloud collapsed?

• A massive sphere with a rotating disk

• A black hole

• A cluster of asteroids

• A new galaxy

What happened to the pockets of matter in the rotating disk?

• They consolidated

• They evaporated

• They exploded

• They disappeared

What caused the central sphere to heat up?

• External radiation

• Energy from its own collapse

• Friction with other celestial bodies

• Impact from meteorites

At what temperature was nuclear fusion ignited in the central sphere?

• A hundred thousand degrees

• A million degrees

• A thousand degrees

• Ten million degrees
