  2. Reflective surfaces (climate engineering) - Wikipedia

    en.wikipedia.org/wiki/Reflective_surfaces...

    The albedo of several types of roofs (lower values means higher temperatures). Reflective surfaces, or ground-based albedo modification (GBAM), is a solar radiation management method of enhancing Earth's albedo (the ability to reflect the visible, infrared, and ultraviolet wavelengths of the Sun, reducing heat transfer to the surface).

  3. Soil acidification - Wikipedia

    en.wikipedia.org/wiki/Soil_acidification

    Aluminum is one of the few elements capable of making soil more acidic. [22] This is achieved by aluminum taking hydroxide ions out of water, leaving hydrogen ions behind. [23] As a result, the soil is more acidic, which makes it unlivable for many plants. Another consequence of aluminum in soils is aluminum toxicity, which inhibits root growth ...

  4. Solar radiation modification - Wikipedia

    en.wikipedia.org/wiki/Solar_radiation_modification

    Schematic with five proposed methods for solar radiation modification technologies. Solar radiation modification (SRM) (or solar radiation management or solar geoengineering), is a group of large-scale approaches to limit global warming by increasing the amount of sunlight (solar radiation) that is reflected away from Earth and back to space.

  5. Spent potlining - Wikipedia

    en.wikipedia.org/wiki/Spent_potlining

    Primary aluminium smelting is the process of extracting aluminium from aluminium oxide (also known as alumina). The process takes place in electrolytic cells that are known as pots. The pots are made up of steel shells with two linings, an outer insulating or refractory lining and an inner carbon lining that acts as the cathode of the ...

  6. Albedo - Wikipedia

    en.wikipedia.org/wiki/Albedo

    Water reflects light very differently from typical terrestrial materials. The reflectivity of a water surface is calculated using the Fresnel equations. At the scale of the wavelength of light even wavy water is always smooth so the light is reflected in a locally specular manner (not diffusely). The glint of light off water is a commonplace ...

  7. Phytoremediation - Wikipedia

    en.wikipedia.org/wiki/Phytoremediation

    Phytoremediation technologies use living plants to clean up soil, air and water contaminated with hazardous contaminants. [1] It is defined as "the use of green plants and the associated microorganisms, along with proper soil amendments and agronomic techniques to either contain, remove or render toxic environmental contaminants harmless". [2]

  8. Acid sulfate soil - Wikipedia

    en.wikipedia.org/wiki/Acid_sulfate_soil

    Sea water is admitted to a bunded polder on acid sulfate soil for soil improvement and weed control, Guinea Bissau Potentially acid sulfate soils (also called cat-clays) are often not cultivated or, if they are, planted with rice , so that the soil can be kept wet preventing oxidation.

  9. Soil - Wikipedia

    en.wikipedia.org/wiki/Soil

    Soil is a major component of the Earth's ecosystem.The world's ecosystems are impacted in far-reaching ways by the processes carried out in the soil, with effects ranging from ozone depletion and global warming to rainforest destruction and water pollution.
