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.).

Category: Volcanoes grow by intrusion and extrusion. An intrusion is magma that moves up into a volcano without erupting. Like a balloon, this causes the volcano grows on the inside. An extrusion is an eruption of material that causes the volcano to grow on the outside.Volcanoes are constructed this way mainly of two materials: lava and ash. Another kind of volcano is called either a stratovolcano or composite-volcano. Mt. St. Helens, Pinatubo, and Fuji are all stratovolcanoes.olcanoes are constructed this way mainly of two materials: lava and ash.
