What is accretion, and how does it relate to the formation of the Earth?

Answer 1

See below

Accretion is a process in which matter comes together and leads to gradual increase in the size of an object

In space , what pulls the matter together is gravitational force.

So , how it is related to earth's formation is that when the Sun was born it had spawned a large amount of rocks and cosmic floatsam.

All these rocks and floatsam gradually started accumulating or accreting onto each other.

Slowly but steadily , they accumulated onto each other to such an extent that it reached a certain size.

Over the course of time , this lump of accreted material from the birth of solar system evolved into our planet , Earth

Answer 2

In the context of Earth's formation, accretion was essential to the planet's formation from smaller particles orbiting the early Sun. These particles gradually merged and collided to form larger bodies known as planetesimals, which in turn collided and accreted to form protoplanets, which in turn led to the formation of the Earth. Accretion is the gradual accumulation of matter through collision and sticking together.

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.
