These magma plumes rise to the surface and form chains of volcanoes. Composite volcano magma contains more silica, SiO 2, than that of a shield volcano and is therefore stickier (more viscous). This stickiness plugs up the volcano, causing pressure to build-up. The result is an explosive, dangerous eruption.omposite volcano magma contains more silica, SiO 2, than that of a shield volcano and is therefore stickier (more viscous).
A prime number is a whole number greater than 1 that can only be divided equally by itself and 1. In other words, prime numbers have only themselves and 1 as factors. Any number may be made by multiplying two or more other numbers together. The numbers you multiply together are called factors of the final number. For prime numbers, their only factors are themselves and 1. Letâs take a look at the numbers 1 through 10 as examples: 1  1: not a prime number by definition. 2  2: can only be divided by 2 and 1, so 2 is prime.
