Thermal stress weathering is an important mechanism in deserts, where there is a large diurnal temperature range, hot in the day and cold at night. [14] As a result, thermal stress weathering is sometimes called insolation weathering, but this is misleading. Thermal stress weathering can be caused by any large change of temperature, and not ...
An accelerated weathering tester, a type of environmental chamber. It exposes materials to alternating cycles of UV light and moisture at elevated temperatures (at T≈60 °C for example), simulating the effects of sunlight, and dew and rain. This is used to test the yellowing of coatings (such as white paints).
This means that people may be ingesting between 3,000 and 4,000 microparticles of plastic from tap water per year. [98] The analysis found particles of more than 2.5 microns in size, which is 2500 times bigger than a nanometer. It is currently unclear if this contamination is affecting human health, but if the water is also found to contain ...

For example, chalk is made up partly of the microscopic calcium carbonate skeletons of marine plankton, the deposition of which induced chemical processes to deposit further calcium carbonate. Similarly, the formation of coal begins with the deposition of organic material, mainly from plants, in anaerobic conditions.
Examples include: sunrise, weather, ... Decomposition – by which organic substances are broken down into a much simpler form of matter; ... Weathering phenomena
