Here's why:
* Formation: Sedimentary rocks are formed from the accumulation and cementation of sediments, which are derived from the weathering and erosion of other rocks. This process happens constantly on the surface, making sedimentary rocks the dominant type in exposed areas.
* Coverage: Although igneous rocks make up the majority of the Earth's crust, they are largely found deep underground or as exposed volcanic features. Sedimentary rocks cover about 75% of the Earth's land surface.
* Examples: Common examples of sedimentary rocks include sandstone, limestone, shale, and coal.
While igneous and metamorphic rocks are also found on the surface, they are not as common as sedimentary rocks.
