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.).
The image below shows the different parts of a volcano. Definitions. Magma-Molten rock beneath Earth's surface. 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.
- When magma reaches the surface it is called lava (pronounced 'larver'). If the level of lava in the crater overflows the rim, it will begin to flow down the sides of the volcano. Different types of lava are more runny than others. and the most runny types can flow down the volcano at over 30 miles per hour. composite volcano is also commonly called a stratovolcano. These volcanoes usually form in subduction zones. Stratovolcanoes form on the continental side of a subduction zone where the melting oceanic crust forms pools of molten rock in a magma chamber.
