Enhanced weathering, also termed ocean alkalinity enhancement when proposed for carbon credit systems, is a process that aims to accelerate the natural weathering by spreading finely ground silicate rock, such as basalt, onto surfaces which speeds up chemical reactions between rocks, water, and air. It also removes carbon dioxide (CO 2) from ...
Basalt (UK: / ˈbæsɔːlt, - əlt /; [ 1 ] US: / bəˈsɔːlt, ˈbeɪsɔːlt /) [ 2 ] is an aphanitic (fine-grained) extrusive igneous rock formed from the rapid cooling of low- viscosity lava rich in magnesium and iron (mafic lava) exposed at or very near the surface of a rocky planet or moon.
The carbonate-silicate cycle is the primary control on carbon dioxide levels over long timescales. [ 3 ] It can be seen as a branch of the carbon cycle, which also includes the organic carbon cycle, in which biological processes convert carbon dioxide and water into organic matter and oxygen via photosynthesis. [ 5 ]
Biologic carbon sequestration is a naturally occurring process as part of the carbon cycle. Humans can enhance it through deliberate actions and use of technology. Carbon dioxide (CO. 2) is naturally captured from the atmospherethrough biological, chemical, and physical processes.
A map of the Juan de Fuca Plate with noted seismic incidents, including the 2001 Nisqually earthquake. The Juan de Fuca Plate is bounded on the south by the Blanco Fracture Zone (running northwest off the coast of Oregon), on the north by the Nootka Fault (running southwest off Nootka Island, near Vancouver Island, British Columbia) and along the west by the Pacific Plate (which covers most of ...
Dunite (/ ˈduːnaɪt, ˈdʌnaɪt /), also known as olivinite (not to be confused with the mineral olivenite), is an intrusive igneous rock of ultramafic composition and with phaneritic (coarse-grained) texture. The mineral assemblage is greater than 90% olivine, with minor amounts of other minerals such as pyroxene, chromite, magnetite, and ...
Deforestation is a primary contributor to climate change, [ 1 ][ 2 ] and climate change affects the health of forests. [ 3 ] Land use change, especially in the form of deforestation, is the second largest source of carbon dioxide emissions from human activities, after the burning of fossil fuels. [ 4 ][ 5 ] Greenhouse gases are emitted from ...
Columnar jointing. Columnar jointing is a geological structure where sets of intersecting closely spaced fractures, referred to as joints, result in the formation of a regular array of polygonal prisms (basalt prisms), or columns. Columnar jointing occurs in many types of igneous rocks and forms as the rock cools and contracts.
