It depends on how you are defining the word 'soft'. Quartzite is the hardest and most durable of the three - no question there. Shale can be crumbled with the tap of a hammer. Some loosely cemented sandstone can be crumbled when squeezed hard enough with your hand and some is well cemented and quite hard.
What else can I help you with?
Which rock below is a sedimentary rock?
Limestone, Sandstone, Shale
What is the major difference between shale and sandstone?
permeability
Why might sandstone act as a reservoir for ground water or oil well shale?
Sandstone is extremely porous and absorbs liquids like a sponge.. Shale is nearly impervious to liquids.
Why can water pass easily through sandstone but not shale?
Because sandstone has wider particles than shale and this let's the water through.
Examples of sedimentary rocks?
Some examples of sedimentary rocks include limestone, sandstone, shale, and conglomerate. Limestone forms from the accumulation of calcium carbonate shell fragments, sandstone is made up of sand-sized mineral particles cemented together, shale consists of fine-grained clay and silt particles compacted over time, and conglomerate is composed of rounded pebbles or gravel held together by a matrix.
What does sandstone morph into?
shale
Where was shale formed?
Shale forms in layers of sandstone or lime.
Is shale also known as sandstone?
No, shale and sandstone are two distinct types of sedimentary rocks. Shale is composed of very fine-grained particles, while sandstone is composed of sand-sized grains that are visible to the naked eye.
Which is the oldest rock sandstone or shale?
Sandstone is typically older than shale, as sandstone forms from the consolidation of sand particles through compaction and cementation, while shale forms from the compaction of clay and silt particles. Sandstone is generally associated with sedimentary environments that occurred earlier in geological history compared to those where shale forms.
Which is most resistant to water erosion quartzite shale or sandstone?
Quartzite
Which rock below is a sedimentary rock?
Limestone, Sandstone, Shale
Rock types on mars?
Sandstone, Limestone, and Shale
Is De Long Shale older or Desert Sandstone?
NO
What is the major difference between shale and sandstone?

What is an examples of a sedimentary Rock?
Sandstone, limestone, shale.
Why might sandstone act as a reservoir for ground water or oil well shale?
Sandstone is extremely porous and absorbs liquids like a sponge.. Shale is nearly impervious to liquids.
Which does not belong shale limestone sandstone or basalt?
Limestone does not belong, as it is primarily composed of calcite, while the other three - shale, sandstone, and basalt - are all composed of different mineral compositions (clay minerals, quartz, and basaltic minerals, respectively).
