The Earth doesn't break apart due to its rotation because it is held together by a combination of gravitational forces and its own structural integrity.
Gravity is the force that attracts objects towards each other. The Earth's mass creates a gravitational force that pulls all its parts inward, effectively keeping it together. Gravity acts uniformly on all parts of the Earth, including its solid surface, oceans, and atmosphere, preventing them from flying apart as the Earth rotates.
Additionally, the Earth's structure provides stability. The Earth is composed of layers, including a solid inner core, a liquid outer core, a solid mantle, and a thin crust. These layers have different properties and interact with each other to maintain the Earth's shape. The solid inner core, in particular, provides a solid center around which the rest of the Earth can rotate.
While the Earth's rotation causes a centrifugal force that pushes outward, it is balanced by the gravitational force pulling inward. This balance of forces allows the Earth to maintain its shape and prevents it from breaking apart.
It's worth noting that the rotation of the Earth does cause some minor effects, such as the flattening of the poles and the bulging at the equator, known as the oblate spheroid shape. However, these effects do not lead to the Earth breaking apart but rather result in a slight distortion of its shape.
