Final answer:

The most common sedimentary rock is sandstone. It is composed of sand-sized grains, primarily quartz, but may also contain feldspar and lithic sand grains. Sandstone is easily identifiable due to its granular and gritty texture and the presence of sedimentary structures such as cross-bedding, mud cracks, and ripple marks.

The most common sedimentary rock is sandstone. It is composed of sand-sized grains, primarily quartz, but may also contain feldspar and lithic sand grains. Sandstone is easily identifiable due to its granular and gritty texture and the presence of sedimentary structures such as cross-bedding, mud cracks, and ripple marks. Fossils are more common in shales, another type of sedimentary rock, due to higher current activity in sandstones.
