Understanding Planetary Shapes

What is a common characteristic of all planets in our solar system?

• They all spin at the same speed.

• They are all round.

• They all have rings.

• They are all made of gas.

How does gravity contribute to the round shape of planets?

• It pulls matter equally from all sides towards the center.

• It pulls matter towards the planet's poles.

• It pushes matter away from the center.

• It only affects the planet's surface.

What initiates the formation of a planet?

• A black hole forming.

• A comet passing by.

• Molten space debris clumping together.

• A star exploding.

Why is Saturn not perfectly round?

• It has a large number of moons.

• It has a unique gravitational pull.

• It spins quickly, causing a bulge at the equator.

• It is made entirely of gas.

What force causes planets to bulge at the equator?

• Centrifugal force

• Magnetic force

• Gravitational force

• Electromagnetic force
