In this article, we will discuss the difference between soil and rock.
Soil is defined as an unconsolidated material that comprises solid particles and voids. The void may comprise either air only, water, or both air and water. If the void is totally occupied by water, then the soil is said to be saturated soil and if the voids are totally occupied by air, then the soil is said to be dry soil.
Soil is used as construction material in various civil engineering projects and it supports structural foundations.
Rock is defined as a natural aggregate of mineralogical composition bounded by strong and cohesive force.
Rocks are an important type of construction material used extensively from primitive times.
Various types of constructions such as stone houses, gabion walls, etc are constructed throughout the world.
Difference Between Soil and Rock
| S.no. | Soil | Rock |
| 1. | Soil is prepared when the disintegration of rock occurs. | Rock is formed when the molten magma gets cools downs after reaching the earth’s surface. |
| 2. | Soil is loose mass. | Rock is hard to mass. |
| 3. | It is used as filling materials on construction sites. | It is used as masonry to construct walls, foundations, etc. |
| 4. | Soil is a very fine size. | Rocks are large in size. |
| 5. | Soils are porous and permeable. | Generally, rocks are hard and impermeable. |
2. Type of Soils
On the basis of the formation of soils, it can be divided into residual soils and transported soils.
a. Residual Soils
The soils remain at the place of formation of soils after the disintegration of rocks. The characteristics of residual soil are similar to parent rock characteristics.
b. Transported soils
The soils are transported a far distance from the place of formation due to the action of different geological agents such as wind, water, glacier, etc. The characteristics of transported soil are different from parent rock characteristics. Soil deposits after transportation by a geological agent.
3. Type of Rocks
There are three kinds of rock are as follows:
1. Igneous Rock
The types of rocks that are formed by cooling down of molten lava are known as Igneous Rocks. Example: Diabase, Diorite, Gabbro, Granite, Pegmatite, and Peridotite.
2. Sedimentary Rock
The types of rock that are formed by gathering or deposition of mineral or organic particles at Earth’s surface or underwater bodies in known as Sedimentary rock. Example: Sandstone, Limestone, and Shale
3. Metamorphic Rock
The type of rock that is formed by igneous and sedimentary rocks due to the action of pressure and temperature. Examples: Phyllite, Schist, Gneiss, Quartzite, and Marble.
