Vonnegut choose AgI crystals because there is nearly the same distance between molecules in the crystal lattice for both ice and AgI, which makes AgI the optimum material to nucleate ice. Usually, progress is made by a series of small improvements on past practices, as a result of bumbling and guesswork.

Vonnegut not only discovered the ice-nucleating properties of AgI, but he also invented a practical way of generating tiny AgI particles to serve as nuclei for ice crystals.

Vonnegut dissolved a mixture of AgI and another iodide in acetone, sprayed the solution through a nozzle to make droplets, then burned the droplets. More than fifty years later, Vonnegut's method continues to be the common way to seed clouds.

Human Knowledge: Foundations and Limits

Release of AgI into an existing supercooled cloud i. The ice crystals nucleated by the AgI will grow and local water droplets will shrink. The latent heat released by converting water vapor or liquid water to ice will increase vertical air motion inside the cloud and aid the convective growth of the cloud.

Raindrops or snowflakes will grow larger by falling through a taller cloud. Also, moist air from evaporated moisture in the soil will be sucked into the base of the cloud by convection i.

Depending on the temperature and humidity below the cloud, the snow may change to rain, or even evaporate, before reaching the ground. AgI is the most common ice nucleus used in cloud seeding, but it is not the only material used. These new droplets fall and either collide or coalesce with other droplets, to form rain drops.

Seeding clouds with either a water spray or hygroscopic materials requires dumping a large mass e. Such use of hygroscopic materials are condensation nuclei, not ice nuclei. While the physics differs in cloud seeding with ice nuclei and with condensation nuclei, both seeding methods have the same legal issues.

There were at least three earlier scientific attempts to modify weather: Emory Leon Chaffee at Harvard University dispensed charged sand from an airplane duringto attempt to modify weather.The IELTS writing task 2 sample answer below has examiner comments and is band score 9.

Department of Environmental Quality - The Water Resources Division (WRD) protects and monitors Michigan's waters by establishing water quality standards, assessing the health of aquatic communities, issuing permits to regulate, discharge and overseeing aquatic invasive species concerns and significant water withdrawals.

The WRD also . The environment The known unknowns of plastic pollution. So far, it seems less bad than other kinds of pollution (about which less fuss is made).

The table below presents an abbreviated geologic time scale, with times and events germane to this essay. Please refer to a complete geologic time scale when this one seems inadequate. By Claire Le Guern Last updated in March Introduction. The world population is living, working, vacationing, increasingly conglomerating along the coasts, and standing on the front row of the greatest, most unprecedented, plastic waste tide ever faced. Essay No. Pollution. The word pollution has been derived from the Latin word pollution, which means to make dirty. Pollution is the process of making the environment land water and air dirty by adding harmful substances to it.

Sep 06,  · Dams are a major source of hydroelectric energy, such as the Hoover Dam on the Colorado River (pictured).

While they collect the vast raw energy provided by water currents, they also create environmental hazards such as silt buildup. Published: Mon, 5 Dec Environmental ethics is the ethical relationship between people and the environment in which we live.
