Does the sun give energy to earth through fission fusion beta decay or alpha decay?

The source of the energy produced by the sun which gives energy to the earth is fusion.
In stars like the sun, the net effect of fusion is that four protons fuse into one alpha particle, with the release of two positrons, two neutrinos (which changes two of the protons into neutrons), and energy, but several individual reactions are involved, depending on the mass of the star. For stars the size of the sun or smaller, the proton-proton chain dominates.

All the above
What happens when an element decays through alpha decay and spontaneous fission?
In alpha decay decay two neutrons and two protons are released from the nucleus and an alpha particle (an Helium nucleus) is released: the atom's nucleus changes in to that of a nucleus two place earlier in the periodic table (Proton number falls by 2, Nucleon number falls by 4) In spontaneous fission a heavy, unstable nucleus autonomously disintegrates and falls in to two smaller nuclei (daughter nuclei) of a similar mass and a few (depending on the nature of the fission) neutrons are released with high kinetic energy.
What kind of rays does uranium 235 and plutonium 239 release?
Plutonium 239 emit: alpha, gamma, spontaneous fission neutrons Uranium 235 emit: alpha, gamma, spontaneous fission neutrons
Is the helium nucleus a byproduct of fission?
Yes, but only if the nuclear disintegration is alpha decay. Alpha decay is only one mode of radioactive decay, and in alpha decay, a helium-4 nucleus (the alpha particle) will appear. Beta decay (two types) and spontaneous fission are also modes of radioactive decay, and different particles appear in those events. Links are provided below to Related questions that will help you sort this out.
What kind of energy will release when nuclei of atoms combine or split?
Fission, the splitting of atoms, and fusion, the combination of atoms, both produce generally the same kinds of energy. Some of the energy comes off as heat. The heated objects are the atoms involved and the alpha or beta particles emitted. The heat in this case can also be viewed as kinetic energy, indicating the speed of the particles. So this energy can be regarded as kinetic or thermal - at the sizes of object we are dealing with here, there is not much difference. Some of the energy is emitted as gamma rays, which are highly energetic photons. This is electromagnetic energy.
What is the origin of nuclear energy?
There are two major types of nuclear energy, fusion and fission. Fusion comes from hydrogen nuclei sticking together in the hearts of stars, which liberates energy. Fission energy comes from the splitting of heavy nuclei. A third type of nuclear energy comes from the slow decay of unstable isotopes, most generally through the release of alpha or beta particles. Both of these are the result of a transmutation of the isotope. Fissionable isotopes are produced naturally in supernova.
How does nuclear fusion occurs?
Nuclear fission occurs when an atom is too massive sustain it's therefore lets of radiation which is split into 3 sections alpha, beta and gamma. Alpha radiation consists of a neutral helium atom, beta is either a Positron or an electron and gamma is merely a huge amount of energy.
What kind of energy is given off from nuclear fusion reaction and from a nuclear fission reaction?
Besides heat and light ? Pure radiation (gamma rays) and particles: alpha, beta, and neutrons (and neutrinos - we think {none actually detected yet except from the sun}).
How are isotopes are formed?
Isotopes are formed either naturally through radioactive decay of elements or artificially through element irradiation by particles as neutrons, protons, electrons, or alpha particles in accelerators or nuclear reactors through nuclear fission or nuclear fusion reactions in nuclear reactors.supernovasparticle acceleratorsnuclear reactorsnuclear explosionsradioactive decay

What kind of radiation is emitted in the following nuclear reaction?

What was used by Rutherford in his experiment that is made of two protons and two neutrons?
Alpha particles. They are identical to ionized nuclei of helium, but have much greater energy (velocity). They are produced in the alpha process of radioactive decay, and in a type of nuclear fission called ternary (three-product) fission.
What happens when an element decays through alpha decay and spontaneous fission?
In alpha decay decay two neutrons and two protons are released from the nucleus and an alpha particle (an Helium nucleus) is released: the atom's nucleus changes in to that of a nucleus two place earlier in the periodic table (Proton number falls by 2, Nucleon number falls by 4) In spontaneous fission a heavy, unstable nucleus autonomously disintegrates and falls in to two smaller nuclei (daughter nuclei) of a similar mass and a few (depending on the nature of the fission) neutrons are released with high kinetic energy.
What type of nuclear radiation is a high energy light?
It is radiation which has had some energy converted into it, most probably after a nuclear fission/fusion reaction when a lot of energy is released, so some of that energy goes into the radiation.
What do you understand by the term radioactive?
It refers to elements that undergo nuclear fission and, in the process, emit atomic particles (alpha and beta particles) and energy (gamma rays).
Why is alpha decay generally found occurring in atoms with large nuclei while beta decay is usually associated with much lighter nuclei?
I believe it has to do with fusion and fission, as all radioactive isotopes want to be as stable as possible.
What are the risks associated with the use of nuclear energy?
The major risk is the only bi products which are capable of radiating harmful radiations such as gamma rays and emitting alpha and beta particles. Otherwise it will be a great boon for the humanity to produce electrical power in a cheaper way. In case of nuclear fusion such a problem does not exist but the pity is that for initiation we need the nuclear fission to produce the high temperature needed for fusion reaction to get started.
