Please describe what you mean by soft and rephrase the question.
Rocks can become soft through the process of heat and pressure, known as metamorphism. This causes the mineral structure of the rocks to rearrange, making them more pliable. High temperatures can also cause rocks to partially melt, making them softer.
Generally speaking, when a geologist talks of "soft rocks" and "hard rocks" what he or she means is "sedimentary rocks" or "igneous and metamorphic rocks". Limestone is a sedimentary rock, and compared to most other rocks, is relatively soft. lol Different limestones have different hardnesses. Most "marbles" are actually hard limestones, because they have not experienced the high pressures and temperatures required for metamorphism.
The materials in soft rocks are soluble or also dissolvant. So anyway, they are made of many materials like hematite that is mostly in almost all of the rocks on the Earth....... In conclusion, the answer is that hematite is the most reasonable because it is the softest mineral found....... My bibliography: google.com, ask.com, yahoo.com, and books from the library... (I know this because I did this for homework..... hehehe)
In the mantle, heat is transferred through convection, where soft rocks flow slowly in cycles known as mantle convection cells. These cells are responsible for the movement of tectonic plates and the transfer of heat from the Earth's interior to the surface.
Rock hardness affects the rate of weathering because softer rocks weather more quickly than harder rocks. Soft rocks are more easily broken down by chemical or mechanical weathering processes, while hard rocks are more resistant to weathering due to their strong mineral structure.
hiya
Because sedimentary rocks are soft rocks
Hard matrix is supposed to be used for digging hard rocks and soft matrix for soft rocks. It's quite confusing to me
i am not sure......

well It Is hard because all rocks are hard
big, soft, hairy and salty rocks

well,the world may never know
The Characteristics are hard,soft,smooth,rough,large,small,etc.
if you throw a rock in soft ground it would make a whole
