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.
(a) A prime 'p' is either relatively prime to a number 'n' or divided it. (b) A product is divisible by a prime 'p' only when 'p' divides one of the factors. Yes all prime numbers are odd, but only even prime number is 2. Since every other even number can be divide by a 2. Prime numbers are a special category of natural numbers or positive integers which are exactly divisible by 1 and the number itself. So, a prime number has exactly two divisors. Prime number is a number which is greater than 1 and which can be efficiently divided by 1 and by itself not by any other number. It is also a whole number. prime number composite. Theorem: Every compositely number could be factored into prime factors and each of these is unique in nature.
