Which of the following best describes the relationship between gas and volcanic eruptions?
A
The more gas magma contains, the more explosive a volcanic eruption will be.
B
The presence
of
gas
in
magma decreases the likelihood of a volcanic eruption.
C
As gas builds up in magma, volcanic eruptions occur once in the magma chamber
and once above ground.
D
Gas found in magma determines only the intensity of eruptions involving
composite volcanoes and not shield volcanoes.

answer is: nuclear fusion produces elements that are heavier than helium.

nuclei combine to form a heavier nucleus, releasing energy.  

for example, fusion of hydrogen atoms at the sun.  

this fusion nuclear reaction is in the inner core of the sun and hydrogen (atomic number 1) is conveted into helium (atomic number 2).  

the inner core is the central region of the sun and all solar energy is produced in the core by nuclear fusion.  

50.23 i believe is correct but don't quote me on that.
