Lead, in the form of lead oxide, PbO, is added to glass to stabilize the matrix and improve the working characteristics of the glass. As a flux, PbO lowers the melting point considerably, and it also decreases the viscosity of the material. Additionally, lead oxide changes (increases) the refractive index of the glass.

It is petrol (gasoline) that has not had its apparent octane level enhanced by tetra ethyl lead (TEL) to reduce knocking in automotive fuel. This was a common practice in the past but now this improvement to petrol burning characteristics is achieved by the addition of other additive packages (MMT, oxygenates including MTBE, TAME, and ETBE) and modified formulations. Some aviation fuels still contain lead (100 octane avgas for piston-engine aircraft).
White lead is lead carbonate. The name "white lead" is also used to describe a lead-containing white paint that was often used as a primer coat on metal. In this context, "red lead" was the red-colored lead-containing primer. White lead is a pigment composed of Lead carbonate and Lead hydroxide. It is used as a rust preventive and it used to be used in house paint until it was recognized that exposure to the old powdering paint and chips created a lead poisoning hazard to people.
Most paint companies had stopped using lead in their paint at that time, however, never assume that paint is lead free. Use a lead paint test to determine if lead if present prior to sanding or scraping.
Atomically, no. Mercury's atomic weight is 200.59 whereas Lead's atomic weight is 207.2. So basically, if you had the exact same amount of Lead and Mercury, lead is heavier.
Sedimentation and erosion will lead to a downward path and deepening bed of streams as one characteristic. In early stream erosion, the erosive activity is primarily vertical.
Sediment is often deposited as the tide rises and falls. As the incoming and outgoing water crosses the beach or banks, sediments are deposited.
the south's staple crops tended to exhaust the soil and lead to erosion
yes the burning of the veld can lead to soil erosion cause of the removal of the sufficient material
Tornadoes can cause some erosion of soil and destroy trees, which can lead to further erosion.
No, The crop rotation is to avoide soil erosion.
Flooding and erosion.
Erosion and deposition can lead to the formation of sedimentary rock.

It can lead to rapid soil erosion.
