sandstone is not harder than flint because sandstone breaks in to smaller pieces.
Granite is typically harder than sandstone. Granite is an igneous rock that forms from the cooling of molten magma, making it more dense and resistant to abrasion compared to sandstone, which is a sedimentary rock.
a sandstone would break more easily because a quartzite is harder. a quartzite is made of sandstone melted together by magma
Conglomerate, limestone, sandstone, and shale.
Yes, flint is generally harder than marble. Flint is a type of sedimentary rock primarily composed of silica, which gives it a high hardness rating on the Mohs scale, typically around 7. In contrast, marble, which is a metamorphic rock primarily composed of calcite, has a hardness rating of about 3 to 4. Therefore, flint is more durable and resistant to scratching compared to marble.

No. Not at all.

"The two basic rocks found in the Mammoth Cave area are limestone and sandstone. Limestone is the "soft" rock (more water soluble) that is dissolved more easily by water. Sandstone and shale are the rocks that are on top of the cave. They are "harder" (less water soluble) and don't let the water soak into the cave." http://www.nps.gov/archive/maca/learnhome/cur_k3_cla.htm
Sandstone can be metamorphosed into quartzite. Heat and pressure bake the sandstone and it becomes extremely hard.

Yes, steel is harder than flint. Steel is a man-made metal alloy that is specifically designed to be strong and durable, while flint is a natural mineral known for its ability to produce sparks when struck against steel due to its hardness and ability to create friction.

Flint is a common name for a form of sedimentary rock called chert, formed from microscopic siliceous (essentially quartz) skeletons of radiolarians. As such the hardness of chert is 7, which is slighly harder than glass and considerably harder than steel. If it will scratch glass it is likely to be flint. Flint is often mistaken for limestone or marble, which is much softer and will not scratch glass.
