¿Por qué el sistema solar es plano?

The video explains the formation of the solar system from a gas and dust cloud, which was initially spherical. Over time, the cloud's rotation and particle collisions led to a flat solar system where planets orbit in the same direction. This process also explains the flatness of Saturn's rings and some galaxies. However, irregularities like Pluto's inclined orbit occur due to non-uniform cloud density and imperfect collisions. The video also discusses why Earth and other planets are not flat, emphasizing the role of intermolecular forces and rotation in maintaining their spherical shape.

What was the primary composition of the cloud that formed the solar system?

• Iron and nickel

• Carbon dioxide and methane

• Hydrogen and helium

• Oxygen and nitrogen

Why is the solar system flat?

• Due to the rotational movement of the original cloud

• Due to the influence of nearby stars

• Because of the magnetic fields of the planets

• Because of the gravitational pull of the sun

What causes Pluto's orbit to be more inclined than other planets?

• The gravitational pull of the sun

• The non-uniform density of the original cloud

• The presence of dark matter

• The influence of nearby galaxies

How do galaxies without large amounts of gas and dust maintain their shape?

• Through frequent star collisions

• By having a strong magnetic field

• By the influence of dark matter

• Due to the lack of collisions between stars

What prevents planets from becoming flat?

• The presence of an atmosphere

• The rotation of the planet

• Intermolecular forces and friction

• The gravitational pull of the sun

Why are planets wider at the equator?

• The influence of solar winds

• Because of the planet's rotation

• The presence of a magnetic field

• Due to the gravitational pull of the moon

What is the primary reason for the spherical shape of planets?

• The presence of an atmosphere

• Intermolecular forces and gravity

• The planet's rotation

• The gravitational pull of nearby stars
