The first thing to understand is what your disability rating represents. In short, the VA takes each individual injury or illness into consideration and gives it a numerical disability rating. Each rating is represented by a percentage divisible by 10 (ex: 10%, 20%, 30%, 40%, etc.).

1 Volcanoes are big holes that let out hot gasses, ash and magma from deep inside the Earth. 2  Many volcanoes are mountains, made up of layers of lava and ash. 3  Many volcanoes have several vents â a main one, and secondary ones that branch off the main vent. The largest active volcano is Mauna Loa. 2  Most volcanoes can be found in countries that have coastlines on the Pacific Ocean â this is called the Ring of Fire. 3  Gas, ash and magma can come out of volcanoes. 4  When magma flows out of a volcano, itâs called lava.
