Soil liquefactionSoil liquefaction occurs when a cohesionless saturated or partially saturated soil substantially loses strength and stiffness in response to an applied stress such as shaking during an earthquake or other sudden change in stress condition, in which material that is ordinarily a solid behaves like a liquid, a sudden physical change termed thixotropy.
LiquidState of matter The formation of a spherical droplet of liquid water minimizes the surface area, which is the natural result of surface tension in liquids.
Phase (matter)In the physical sciences, a phase is a region of material that is chemically uniform, physically distinct, and (often) mechanically separable. In a system consisting of ice and water in a glass jar, the ice cubes are one phase, the water is a second phase, and the humid air is a third phase over the ice and water. The glass of the jar is a different material, in its own separate phase. (See state of matter § Glass.)
SolidSolid is a state of matter in which atoms are closely packed and are difficult to move past each other. Solids resist compression, expansion, or external forces that would alter its shape, with the degree of resistance being dependent upon the specific material under consideration.
Materials scienceMaterials science is an interdisciplinary field concerned with understanding the relationships between the structure of materials and their properties and using this knowledge to design materials for specific applications. The internal structure of a material—from atomic arrangements to microscopic features—strongly influences its mechanical, electrical, thermal, and optical behavior.
Fluid dynamicsAspects of fluid mechanics involving fluid flow Computer generated animation of fluid in a tube flowing past a cylinder, showing the shedding of a series of vortices in the flow behind it, called a von Kármán vortex street.
NatureNature, in the broadest sense, is the physical world or universe. In this general sense nature refers to the laws, elements and phenomena of the physical world, including life. Although humans are part of nature, human activity or humans as a whole are often described as at times at odds, or outright separate and even superior to nature.
GasSuspended particulates indicate the movement of the surrounding gas.Gas is a state of matter with neither fixed volume nor fixed shape. It is a compressible form of fluid, in contrast to a liquid. A pure gas consists of individual atoms (e.g. a noble gas like neon), or molecules (e.g. oxygen (O2) or carbon dioxide). Pure gases can also be mixed together such as in the air. What distinguishes gases from liquids and solids is the vast separation of the individual gas particles.
SedimentIn Earth and planetary sciences, sediment is a solid material made of loose particles that is transported to a new location where it is deposited. It occurs naturally and, through the processes of weathering and erosion, is broken down and subsequently transported by the action of wind, water, or ice or by the force of gravity acting on the particles.
IndonesiaIndonesia, officially the Republic of Indonesia, is a country in Southeast Asia and Oceania, between the Indian and Pacific oceans. Comprising between 13,000 and 17,000 islands, including Sumatra, Java, Sulawesi, and parts of Borneo and New Guinea, it is the world's largest archipelagic state and the 14th-largest country by area. Indonesia has extensive tropical forests and marine ecosystems that support one of the world's highest levels of biodiversity.
GeologyGeology is a branch of natural science concerned with the Earth and other astronomical bodies, the rocks of which they are composed, and the processes by which they change over time. The name comes from Ancient Greek γῆ (gê) 'earth' and λoγία (-logía) 'study of, discourse'. Modern geology significantly overlaps all other Earth sciences, including hydrology. It is integrated with Earth system science and planetary science.
ArtificialityArtificiality (the state of being artificial, anthropogenic, or man-made) is the condition of being the product of intentional human manufacture (namely, by artifice), rather than occurring naturally through processes not involving or requiring human activity. ConnotationsArtificiality often carries the implication of being false, counterfeit, or deceptive.
