How do the four fundamental forces play into earth's formation?

Answer 1

Gravity is the only one of the four directly related.

The four fundamental forces are the strong force (nuclear), the weak force (radiation), electro-magnetism and gravity. For purposes of the earth's formation, only gravity was in play.

The structure, composition, and dynamics of Earth are shaped by the four fundamental forces: weak nuclear, strong nuclear, electromagnetic, and gravitational. Weak nuclear plays a role in processes like radioactive decay, which affects the composition of Earth's interior. Strong nuclear binds atomic nuclei together, providing stability to matter, including elements present in Earth's composition. Initially, gravitational force pulled together gas and dust to form the solar nebula, leading to the formation of the Sun and the planets, including Earth.

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
