Rammed earth is more often considered for use in walls, although it can also be used for floors. Rammed earth and caliche block can be used for structural walls, and offer great potential as low-cost material alternatives with low embodied energy. In addition, such materials are fireproof. Caliche block and rammed earth can be produced on-site.
Earth structure – Building or other structure made largely from soil; Gabion – Cage full of rock; Keyline design – Landscaping to optimize water usage; Land restoration – Process of restoring land to a different state; Grading (earthworks) – In civil engineering, creating a profile; Spoil tip – Pile built of accumulated spoil
Economic geology is concerned with earth materials that can be used for economic and industrial purposes. These materials include precious and base metals, nonmetallic minerals and construction-grade stone. Economic geology is a subdiscipline of the geosciences; according to Lindgren (1933) it is “the application of geology”.
The walls are formed by compacting earth mixed with stone, bamboo, wood and other readily available materials, and are to 6 feet (1.8 m) thick. The result is a well-lit, well-ventilated, windproof and earthquake-proof building that is warm in winter and cool in summer.
Solidified lava flow in Hawaii Sedimentary layers in Badlands National Park, South Dakota Metamorphic rock, Nunavut, Canada. Geology (from Ancient Greek γῆ (gê) 'earth' and λoγία () 'study of, discourse') [1] [2] is a branch of natural science concerned with the Earth and other astronomical objects, the rocks of which they are composed, and the processes by which they change over time.

Surficial processes are the physical and chemical phenomena which cause concentration of ore material within the regolith, generally by the action of the environment. This includes placer deposits, laterite deposits, and residual or eluvial deposits. Superficial deposits processes of ore formation include; Erosion of non-ore material.
A dune is a large pile of wind-blown material, typically sand or snow. As the pile accumulates, its larger surface area increases the rate of deposition in a positive feedback loop until the dune collapses under its own weight. This process causes dunes to move in the direction of the wind over time. [6] [7] Death Valley Mesquite Flats sand dunes.
Aeolian processes, also spelled eolian, [1] pertain to wind activity in the study of geology and weather and specifically to the wind's ability to shape the surface of the Earth (or other planets). Winds may erode , transport, and deposit materials and are effective agents in regions with sparse vegetation , a lack of soil moisture and a large ...
