Weathering and Erosion
Imagine a towering mountain slowly crumbling into gravel and sand over thousands of years: this is weathering in action.
Weathering is the breakdown of rocks on the Earth's surface. This process breaks down solid rock into smaller pieces called sediments, ranging in size from tiny particles like silt to large chunks like boulders. Weathering may also cause the minerals at the Earth's surface to change form.
Once sediments are formed due to weathering, they are transported by a process called erosion.
Flowing water is a powerful agent that helps this process. It carries and deposits sediments along its path. Wind plays a key role in moving particles in dry, arid regions. Ice and glaciers grind and transport massive amounts of sediment. Even gravity helps, pulling rocks and soil downhill.
Eventually, these sediments settle in new locations by a process called deposition. This process shapes river deltas, sandy beaches, and rolling hills.
Together, weathering, erosion, and deposition work over millions of years, transforming rugged mountains into gentle hills and flat plains, constantly reshaping the landscape.
