It is the same virus that causes chickenpox. Most people were infected with this virus (as chickenpox) when they were children. The body never completely gets rid of the virus, and the virus remains inactive in certain nerve cells in the body. Later in life, often triggered by stress or illness, the virus can become active again, causing shingles. Symptoms of shingles may include a rash (usually on only one side of the body) and burning or tingling pain. Usually, the rash forms blisters that may break and ooze. If this happens, you may be able to spread the shingles virus to people who have never had chickenpox. Shingles pain can be very severe.
Igneous Rock. Molten material within the Earth is called magma. In simple terms magma can be thought of as molten rock. When magma cools, it solidifies to form rock which is called igneous rock. That is deceptively simple, since the solidification process can be very complex.
Magma can be formed from the subduction and melting of cold, dense, wet oceanic crust at some convergent plate margins. The moisture in the rock assists in the melting of the â¦ crust and the rock surrounding it. Magma is also formed at hot spots in the mantle where hot material undergoes decompression melting as it rises. Decompression melting also occurs at the mid-ocean ridges where new oceanic crust is formed from rising mantle rock. + 28 others found this useful. Liberty Salter.
