Zebra mussels are located primarily in areas in the eastern united states rather than in the western united states because This animal was introduced to the eastern United States and is now widespread across the continent.
Zebra mussels are small freshwater mussels. The species was originally native to lakes in southern Russia and Ukraine, but was mistakenly introduced to many other regions and has become an invasive species in many countries around the world.
Zebra mussels have few natural enemies in North America. Some species of fish (catfish, sunfish, freshwater drums, etc.) and ducks are known to eat them, but these species do not provide effective control.
Sticks to all hard surfaces including native mussels, turtles, and crustacean shells. They destroyed boat engines, polluted beaches, and damaged boat ramps and docks in the Midwest. Zebra mussel droppings can also cause taste and odor problems in drinking water sources.

Chemical composition is the primary term used for the classification of silicates, carbonates, sulfates, and oxides.
On the basis of their chemical compositions, scientists classify minerals. Native Elements, Sulfides, Sulfates, Halides, Oxides, Carbonates, Phosphates, Silicates, and Organic Minerals were the first nine mineral classes classified in the Dana Classification System.
The arrangement, kind, and ratio of atoms in chemical substance molecules are referred to as chemical composition. When chemicals are added to or removed from a substance, when the ratio of substances changes, or when other chemical changes take place in chemicals, the composition of the substance changes.

Impervious surfaces are entirely man-made and, except from exposed natural rock cropping, constitute an artificial component of most ecosystems. Basically, water cannot soak naturally into the ground in constructed regions with large amounts of impermeable surfaces; instead, it rushes over the landscape, bringing pollution and biological contaminants into our rivers, harming fish, wildlife, and people. All hard surfaces, including paved roads, parking lots, roofs, and even densely compacted soils like sports fields, are referred to as "impervious surfaces." Residential roofs, public buildings, parking lots, commercial buildings, and bedrock near the soil's surface are a few examples of impermeable surfaces. Impervious surfaces are generally understood to include heavily compacted soils, concrete, asphalt, roofs, and other construction materials.
