Formation of Terrestrial Planets

The formation of terrestrial planets is a complex process that begins within protoplanetary disks surrounding newly formed stars. In these disks, small dust particles collide and stick together, gradually accreting into larger bodies known as planetesimals. Over time, these planetesimals further collide and merge, forming larger bodies called protoplanets.

As protoplanets grow in size, their gravitational pull increases, allowing them to attract more material and undergo differentiation. This process involves the separation of materials based on their densities, leading to the formation of distinct layers within the growing planet. In the case of terrestrial planets like Earth, this differentiation resulted in the formation of a metallic core, a silicate mantle, and a crust.

The final stages of terrestrial planet formation involve accreting enough material to become spherical and clearing out their orbital paths of debris. This process, known as planetary accretion, marks the completion of the formation stage and sets the stage for further geological evolution. Ultimately, the mineralogical composition of terrestrial planets is a product of their unique formation histories, influencing their surface features and geological processes.
