Question

Many planets are formed by a process called accretion, where chunks of material are drawn to bigger chunks of material and are slammed together until enough material has been gathered to produce a planet. Which of the following forces is responsible for accretion? A) Nuclear B)Gravitation C) Magnetism D) Electromagnetic Energy

Answer 1

B) Gravitation. Gravity is the most powerful force in space and is the only reason why accretion is even possible.

Answer 2

Answer: B)Gravitation

Explanation:

Gravitational force is a force of attraction that exists between any two particles having mass. The gravitational force is directly proportional to masses of two objects and inversely proportional to square of distance between them.

Chunks are drawn to bigger chunks of material and are slammed together due to gravitational force. The chunks of material clumps together and forms a planet.
