Here's why:
* Sedimentary rocks are formed by the accumulation and cementation of sediments, which are small particles of rock, minerals, and organic matter.
* Land is a primary source of these sediments, weathered and eroded from mountains, hills, and other landforms.
* Deposition occurs when these sediments are carried by water, wind, or ice and settle in a new location, often in a low-lying area like a lake or riverbed.
While some sedimentary rocks can form in marine environments, the ones specifically formed from land-based sediments are often classified as terrestrial sedimentary rocks.
