The most common procedure is to apply a ferrous sulphate based moss killer to kill the moss, wait a couple of weeks and then rake the moss out. The reasoning is that you can spread the moss to other parts of your lawn if it is alive thus causing an even bigger problem.he most common procedure is to apply a ferrous sulphate based moss killer to kill the moss, wait a couple of weeks and then rake the moss out.

Most Abundant Metal in the Earthâs Crust. Aluminium â Itâs the most abundant metal in the Earthâs crust, yet it entirely escaped our notice until 1825. You might say it was hidden in plain sight. Aluminium is a highly reactive metal, meaning it readily undergoes chemical reactions with other elements and compounds to form different substances. As a result, nearly all of the naturally occurring aluminium atoms on Earth ended up tucked away in the molecules of more than 270 different minerals, including gemstones like emeralds and rubies.
Answer: The most abundant element in the universe is hydrogen, which makes up about 3/4 of all matter! Helium makes up most of the remaining 25%. Oxygen is the third most abundant element in the universe. All of the other elements are relatively rare. The chemical composition of the earth is quite a bit different from that of the universe. The most abundant element in the earth's crust is oxygen, making up 46.6% of the earth's mass. Silicon is the second most abundant element (27.7%), followed by aluminum (8.1%), iron (5.0%), calcium (3.6%), sodium (2.8%), potassium (2.6%). and magnesium (2.1%). These eight elements account for approximately 98.5% of the total mass of the earth's crust.
