The Sun provides all of the energy we need. Without that energy, life on Earth would not exist.

Why can elements be produced in the sun but not in the earth atmosphere?
Over time, the fusion reactions can form as the reactions that form nuclei of slightly heavier elements, such as carbon, nitrogen, and oxygen. Thank you = )
What is the difference between the suns nuclear reactions and man made ones?
The sun's nuclear reactions are based on fusion of atoms (hydrogen atoms are fused together to form helium or lithium mainly) whereas earth-bound nuclear reactions are based on fission (uranium atoms are smashed apart to form (often radioactive) fragments and energy) There has been research on earth-bound nuclear fusion for many years (JET project in the UK) and ITER, but there is still a long way to go before we can mimic the sun!
Primary source of the suns energy is?
The primary source of the suns energy is nuclear fusion of hydrogen. Nuclear fusion occurs in the core of the Earth.
Solar energy is produced by?
Nuclear fusion in sun. Solar Cells on Earth.
The phenomena occurring on the surface of the sun?
the surface of the sun is a phenomena for the earth surface from the sun
On Earth what's being investigated to contain fusion reactions?
magnetic confinement inertial confinement
Compare the role of nuclear fusion in the formation of Earth's naturally occurring elements and in the creation of synthetic elements in the laboratory?
Creation of synthetic elements in the laboratory is not based on nuclear fusion.
What does Nuclear Fusion have to do with stars?
The stars produce their heat from nuclear fusion reactions. Work on earth to produce controllable nuclear fusion is concentrating on one particular reaction, between deuterium and tritium, because it is the easiest to get going (though hard enough!). Stars operate with other reactions but all of the nuclear fusion type. You can read more in Wikipedia 'Nuclear fusion'
Is nuclear fusion only theoretical?
No, it is occurring in all stars including our sun, and we would not exist otherwise. On Earth it is still experimental

What is the difference between the nuclear reactions taking place in the sun and the nuclear reactions taking place in a nuclear reactor?
The sun's nuclear reactions are fusion reactions at extremely high temperatures and pressures, while the nuclear reactor's nuclear reactions are fission reactions at typical temperatures and pressures for earth.
What is the explanation for the process of nuclear fusion?
Fusion reactions occur under immense pressures, such as those found in the centre of the sun. To artificially produce fusion reactions here on earth, we either use MCF (magnetic confinement fusion) or ICF (inertial confinement fusion) to create the pressure and temperature necessary for small elements to fuse together, releasing energy.
Why is it more difficult to start a fusion reaction than fission?
Fission reactions start naturally if the proportion of U-235 is high enough; there is evidence this has happened in places in Africa in the distant past of Earth's history. Fusion reactions require more heat and pressure than we really know how to provide so as to keep a reaction going.
How long does it take for heat of the Sun fusion reactions to reach the sun's surface?
From the surface of the sun the heat radiations take 8 minutes to reach the surface of hte earth.
