Basalt is a type of volcanic rock that is formed from the solidification of molten lava. It is an igneous rock, meaning it is formed through the cooling and solidification of magma or lava. Basalt is one of the most common rock types on Earth, and it can be found in various locations around the world, both on land and under the ocean floor.

In general, basalt is more affordable than granite. This is because basalt is more abundant than granite. It is also easier to extract and process. However, the cost of granite can be cheaper than basalt if it is extracted and processed in certain locations. It is also worth noting that the cost of each rock will vary depending on the purpose.

Measurement of Acid Neutralizing Capacity . Introduction . Acid neutralizing capacity (ANC) is a measure of the ability of water to neutralize acid inputs. Lakes with high ANC (such as Cayuga Lake) can maintain a neutral pH even with some acid rain input whereas lakes with an ANC less than the acid input will not maintain a neutral pH.

Acid Rain: There are several definitions of what makes an acid: the Arrhenius definition, in which acids are compounds that react with water to create hydronium ions, the Br{eq}o {/eq}nsted-Lowry definiton, by which an acid is a proton donor, and the definition, in which an acid is a compound or ion capable of of receiving two electrons.

Lakes in limestone regions have a higher acid-neutralizing capacity. Limestone is more susceptible to acid than granite, and lakes in limestone regions are therefore more acidic. Lakes in granite areas tend to have lower pH values than lakes in limestone regions. Lakes in limestone regions contain Ca2+ ions, which neutralize excess acid.
