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.
Geodynamics is a subfield of geophysics dealing with dynamics of the Earth.It applies physics, chemistry and mathematics to the understanding of how mantle convection leads to plate tectonics and geologic phenomena such as seafloor spreading, mountain building, volcanoes, earthquakes, faulting.
Earth's regolith [8] [9] [10] includes the following subdivisions and components: soil or pedolith; alluvium and other transported cover, including that transported by aeolian, glacial, marine, and gravity flow processes. "saprolith'", generally divided into the upper saprolite: completely oxidised bedrock
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.

Environmental geology has reduced the negative environmental impacts of mining as it has been used in litigation toward mining. In some countries like Brazil [8] and Australia [9] for example, it is decreed by law that sites must undergo rehabilitation after a mining operation has ceased. Prior to any mining, an assessment is also necessary to ...
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”.
Diastrophism is the process of deformation of the Earth's crust which involves folding and faulting. Diastrophism can be considered part of geotectonics . The word is derived from the Greek διαστροϕή diastrophḗ 'distortion, dislocation'.
The materials left after the rock breaks down combine with organic material to create soil. Many of Earth's landforms and landscapes are the result of weathering, erosion and redeposition. Weathering is a crucial part of the rock cycle ; sedimentary rock , the product of weathered rock, covers 66% of the Earth's continents and much of the ocean ...
