Where do boulders come from?

Boulders originate from the weathering and erosion of larger rock formations, such as mountains or cliffs. Over time, physical processes like freeze-thaw cycles, water erosion, and glacial movement break down the rock into smaller fragments, eventually forming boulders. They can also result from volcanic activity, where lava cools and solidifies into large masses. Once formed, boulders can be transported by natural forces like rivers, glaciers, or landslides.
