¿Por qué los planetas son redondos? ¿Por qué giran los planetas?

The video explains why planets are spherical due to gravity, contrasting this with the shapes of asteroids, which are not influenced by strong gravity. It discusses surface tension and isostatic adjustment, which limit mountain heights. The formation of the solar system is described, highlighting how planets formed from a spinning disk of gas and dust, maintaining rotation due to angular momentum. The video also covers the unique rotation of Venus and Uranus, which differ from other planets due to past collisions or interactions.

Why do planets tend to have a spherical shape?

• Due to the presence of an atmosphere

• Because they are spinning rapidly

• Due to the force of gravity pulling material towards the center

• Because they are made of liquid

What is the process called that limits the height of mountains on Earth?

• Surface tension

• Isostatic adjustment

• Tectonic shift

• Gravitational pull

How did the solar system begin to form?

• From a large asteroid impact

• From a cloud of gas and dust

• From a collision of two stars

• From a supernova explosion

What phenomenon explains why planets continue to rotate in the same direction?

• Solar winds

• Magnetic fields

• Gravitational pull

• Conservation of angular momentum

Which planet rotates in the opposite direction to most others in the solar system?

• Neptune

• Venus

• Jupiter

• Mars
