because the sandstone is smooth and big
A sedimentary rock formed from sand deposits is called sandstone. Sandstone is made up of grains of sand that have been compacted and cemented together over time, typically in a beach or desert environment. It often has a grainy texture and can be found in various colors depending on the mineral content of the sand.
A sedimentary rock formed from sand deposits is called sandstone. Sandstone is composed of grains of sand that are cemented together by minerals, creating a rock that is often used as a building material due to its durability and ease of cutting.
Compressed and cemented sand is called sandstone.
A light brown rock is commonly referred to as sandstone. Sandstone is a sedimentary rock composed of sand-sized minerals or rock grains. It ranges in color from light brown to tan.
When sandstone goes through heat and pressure, it can be transformed into a metamorphic rock known as quartzite. Quartzite forms from the recrystallization of quartz grains in the original sandstone, resulting in a harder and more compact rock with a glossy appearance.
Sandstone can be metamorphosed into quartzite. Heat and pressure bake the sandstone and it becomes extremely hard.
Quartz sandstone, aka arenite, can form the metamorphic rock called quartzite.
The most common metamorphic rock associated with the regional, contact, or depth of burial metamorphosis of sandstone is quartzite.
Sand grains cemented together into solid stone are called sandstone. Sandstone is a sedimentary rock formed from the compression and cementation of sand grains over time.
The layers of any sedimentary rock are called strata.
Sandstone typically does not have crystals. It is primarily composed of sand-sized mineral particles that are cemented together, giving it a granular appearance. If sandstone does contain crystals, they are usually very small and not easily visible to the naked eye.

The cliffs and canyons of Starved Rock are made of an Ordivician age sandstone called St. Peter sandstone.

If the sandstone is below the basalt layer, it is older. Though caution is advised, to make sure it is really a basalt layer and not an intrusion of gabbro. Other indicators that the sandstone is older is evidence of alteration to the sandstone where the two meet (called a "baked contact") and pieces of sandstone being found in the the basalt.
