The forces that break rocks vary and in most cases are classified as mechanical or chemical forces. Weathering is one of the common ways that rocks are broken down into smaller particles.

The main forces that break rocks are weathering, which includes mechanical, chemical, and biological processes. Mechanical weathering involves physical forces like temperature changes and frost action breaking down rocks. Chemical weathering occurs when rock minerals react with water and air, leading to their breakdown. Biological weathering involves living organisms like plants and animals contributing to rock breakdown through physical and chemical processes.
It is called faulting when plate movement caused by tectonic forces causes rocks to break along a fracture or fault line.
The process in which rocks first bend and then break is called deformation. Deformation occurs when rocks experience stress, which can be caused by tectonic forces, pressure, or temperature changes. Initially, rocks may bend or fold under this stress, but if the stress is too great, the rocks can eventually break or fracture.
This process is called "faulting," where rocks break and slide against each other due to tectonic forces, creating faults in the Earth's crust.
When rocks break, they move along the surface in a process known as faulting. This movement can occur due to tectonic forces, causing the rocks to break and move along fractures known as faults.
Weathering processes like freeze-thaw cycles, plant roots, and chemical reactions from acid rain can break down rocks on Earth's surface. These forces contribute to the process of rock weathering and eventual erosion.
