In general, weathering tends to produce rounded rocks. Weathering also produces regolith (pronounced REH-gah-lith). This is the layer of loose, uncemented rocks and rock fragments of various size that lies beneath the soil and above the bedrock (general term for the solid rock that underlies the soil).

Soil is the upper layer of the ground comprising of a mixture of sand, silt, clay, loose rock fragments, and organic matter that can support the growth of rooted plants. The relative proportions of sand, silt and clay determine the texture and size of the pores of the soil, which affects its ability to allow air and water to penetrate/infiltrate.

These rocks are classified according to their origins, or processes by which they formed:. 1. igneous rocks: formed by the cooling and hardening of magma (molten rock) from inside Earth. 2. sedimentary rocks: formed by the compaction and cementing of layers of sediment (rock fragments, plant and animal remains, minerals from water). 3. metamorphic rocks: formed by the effect of heat and

1) Clastic (or detrital) sedimentary rocksForm from the cementation of sediment grains that come from pre-existing rocks. This is the most common sedimentary rock type. Clastic sedimentary rocks are classified by grain size, and to a lesser extent by chemical composition.

Sedimentary rock Wikipedia

In this way, loose clasts in a sedimentary rock can become "glued" together. When sedimentation continues, an older rock layer becomes buried deeper as a result. The lithostatic pressure in the rock increases due to the weight of the overlying sediment. This causes compaction, a process in which grains mechanically reorganize.

Rock fragments will also remain where the rocks are not completely weathered. Not only is quartz the most stable of the common rock forming minerals in chemical weathering, its high hardness and lack of cleavage make it quite resistant to mechanical weathering. Quartz is itself an agent of mechanical weathering in the form of blowing dessert sand.
