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.).

Parasitic Cone-A small cone-shaped volcano formed by an accumulation of volcanic debris.Sill-A flat piece of rock formed when magma hardens in a crack in a volcano.Vent-An opening in Earth's surface through which volcanic materials escape.Flank-The side of a volcano.hroat-Entrance of a volcano. The part of the conduit that ejects lava and volcanic ash. Ash-Fragments of lava or rock smaller than 2 mm in size that are blasted into the air by volcanic explosions.
Volcanic eruptions. When a volcano erupts three types of material come to the surface: lava, small pieces of rock or ash, and gas. Magma that spreads out of a volcano slowly is called lava. It can reach temperatures of up to 1,200Â° C and glows red to white when it flows.In most cases, lava mixes with steam and gas.hen a volcano erupts hot gases and liquid rock come up to the surface from inside the earth. The material sometimes slides down mountains as lava or is hurled into the air as ash or small rocks. Volcanoes often destroy the land around them completely.
