Environmental materials are natural materials found in nature such as wood, sand, rock, etc.

Concrete is a man-made material composed of cement, sand, and aggregate. While not a true rock, concrete can still be considered part of the rock cycle when broken down into its original components. These components, such as sand and gravel, are natural materials that can be eroded and transported in the same way as rocks, eventually forming new sedimentary rocks.
The inorganic part of soil is made up of particles of sand, silt, and clay. These inorganic components arise from weathered parent rock, over tens of thousands of years.
Materials such as permeable soils, sand, gravel, and porous rock allow water to pass through them due to their interconnected pore spaces. These materials facilitate the movement of water, making them important in processes like infiltration and groundwater recharge. Conversely, impermeable materials like clay and solid rock restrict the flow of water.
Wind can deposit a variety of materials including sand, silt, and dust. These materials can accumulate to form features like sand dunes and loess deposits. Additionally, wind-blown particles can affect the erosion and weathering of rock surfaces.
Soil can contain a variety of rock materials, such as sand, silt, and clay particles derived from the weathering and erosion of rocks. It may also contain larger rock fragments and minerals like quartz, feldspar, and mica that have been broken down over time. The specific rock materials in soil will depend on the parent rock type in the area and the processes of weathering and erosion that have occurred.
Crushed rock sand is produced by crushing hard rocks, whereas natural sand is formed by natural weathering processes. Crushed rock sand usually has rougher particles compared to natural sand, which can affect the workability and strength of the mortar mixture. Additionally, natural sand may contain impurities or organic materials that can impact the performance of the mortar.
The element found in sand, rock, and soil is silicon. Silicon is abundant in the Earth's crust and is a major component of materials like sandstone, granite, and clay minerals.
Lithification is the compaction of materials into a sedimentary rock, such as sandstone.
In deserts, arches and mushroom rocks are formed when the sand in sand storms blows it and other materials against the rock which eventually erodes the rock into interesting shapes such as arches. ~Tom1819
A sandblasted rock has undergone a process where fine grains of sand or abrasive materials are forcibly propelled against its surface to create a textured finish. This process can alter the appearance and feel of the rock, giving it a rougher or weathered look compared to a regular rock, which retains its natural state.
