Central Lake District is occupied by a glaciated massif of mountains and ridges intersected by wide, steep-sided 'U' shaped valleys often occupied by ribbon lakes. The southern Lake District fringes are typified by limestone ridges flanked by wooded slopes and lake-filled valleys. On the mountain fringes the fells give way to more muted scenery; low hills and valleys often filled by drumlin ...

Lake freighter - Wikipedia

Lake freighters, or lakers, are bulk carrier vessels that ply the Great Lakes of North America. These vessels are traditionally called boats, although classified as ships.. Since the late 19th century, lakers have carried bulk cargoes of materials such as limestone, iron ore, grain, coal, or salt from the mines and fields of the upper Great Lakes to the populous industrial areas farther east.

5/16/2008 · The limestone is made up of Calcium Carbonate, CaCO3. When the acid rain falls into the lake it reacts with the CaCO3 that dissolves into the lake and creates CO2 gas. This reaction neutralized the effects of the acid rain. Granite is made up of SiO2, and other minerals that would not react and neutralize the acid rain.

What happens when acid reacts with limestone? | Questions ...

6/15/2008 · Limestone is mostly made up of the mineral calcium carbonate (CaCO3). This is not very soluble, so rocks don't dissolve very quickly. But if you add an acid, you add hydrogen ions (H+), which will react with the carbonate to form hydrogen carbonate HCO3- ions, which are very soluble in water, and the limestone will dissolve. Or, if there is more acid, two hydrogen ions will

Limestone - Encyclopedia

They are readily dissolved by carbonated waters and acid solutions, and their place may then be occupied by deposits of a different kind. The silification of oolites and coral rocks and their replacement by iron ores above mentioned are examples of this process. Many extensive hematite deposits are in this way formed in limestone districts.

Limestone and Acid Rain

The presence of limestone and other calcium carbonate rock in lakes and streams helps to maintain a constant pH because the minerals react with the excess acid. However, acid rain eventually can overcome the buffering capacity of the surface water.
