What effect does temperature have on the characteristics of magma?
The temperature of the magma will affect its viscosity depending on its chemistry. Some minerals crystallize at higher temperatures than others, meaning that portions of the magma may have already solidified. At lower temperatures, the majority of the constituent minerals will have crystallized and solidified, leaving the magma highly viscous.

Answer : option a) 84explanation :

considering the question as per the attachment

here we can see that the radon nuclide has 222 as the atomic mass number and 86 as the atomic number.

when it undergoes nuclear fission it gives polonium which has atomic mass number as 218 and atomic number will be 84 along with a helium nucleus which has 4 atomic mass number and 2 as its atomic number.

222 = 218 + 4 (atomic mass number)

86 = ? + 2; therefore ? = 86-2 = 84.

the atomic mass number of polonium will be 84.

The answer is true a geyser can reach up to 205 degrees fahrenheit
