because the sandstone is smooth and big
Sandstone is formed from deposits of sand.
Is a called a plate
Compressed and cemented sand is called sandstone.
Sandstone that has experienced heat and high pressure can form a metamorphic rock called quartzite.
Sandstone cannot freeze as it is already a solid. Sometimes rainwater gets into the pores of a rock like sandstone. When the water freezes it expands and pushes on the rock. Then the water melts, and the whole cycle can be repeated over and over, eventually causing the rock to crumble. This is called freeze-thaw weathering.
sandstone has crystals, big ones not small ones
Sandstone can be metamorphosed into quartzite. Heat and pressure bake the sandstone and it becomes extremely hard.

The most common metamorphic rock associated with the regional, contact, or depth of burial metamorphosis of sandstone is quartzite.
Quartz sandstone, aka arenite, can form the metamorphic rock called quartzite.
Compressed and cemented sand is called sandstone.
The layers of any sedimentary rock are called strata.
The cliffs and canyons of Starved Rock are made of an Ordivician age sandstone called St. Peter sandstone.
Sandstone that has experienced heat and high pressure can form a metamorphic rock called quartzite.
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.
