The average heat flow from the earth''s surface is 87mW/m 2 – that is, 1/10,000th of the energy received from the sun, meaning the earth emits a total of 47 terawatts, the equivalent of several
The source of the sun''s heat and light energy is nuclear fusion, which is a process that happens within the sun''s core (proton-proton fusion). What is the main source of energy on Earth? The main source of energy on Earth is solar energy.
The source of the sun''s energy is: A. nuclear fusion B. nuclear fission C. crude oil Your solution''s ready to go! Our expert help has broken down your problem into an easy-to-learn solution you can count on.
Nothing could live on the Sun, but its energy is vital for most life on Earth. The temperature in the Sun''s core is about 27 million degrees Fahrenheit (15 million degrees Celsius) – hot enough to sustain nuclear fusion. This creates outward pressure that supports the star''s gigantic mass, keeping it from collapsing.
Neither chemical burning nor gravitational contraction can account for the total amount of energy radiated by the Sun during all this time. Solar energy is produced by interactions of particles—that is, protons, neutrons, electrons, positrons, and neutrinos. Specifically, the source of the Sun''s energy is the fusion of hydrogen to form helium.
The energy we receive from the Sun provides light and heat, drives our planet''s winds and ocean currents, helps crops grow, and more. Throughout history, humans have used technology to harness the Sun''s energy as a source of
The Sun''s Energy Source. Dr. Iddo Magen. September 21, 2016. 10 min. there remains another five billion years for it to spread its light and heat. Nuclear Fusion. which also occurs in many other stars in addition to the sun. Nuclear fusion is a process that requires energy to initiate and does not occur spontaneously, however the
The Sun is fueled by a process known as fusion: four hydrogen atoms undergo a series of collisions and eventually fuse together to form one helium atom. Such reactions—which occur in the Sun 100 million quadrillion quadrillion times each second—release a significant quantity of energy as predicted by E=mc 2. The mass of one helium atom is
THE SUN: A NUCLEAR POWERHOUSE Chapter 16 The Sun: A Nuclear Powerhouse 563 Scientists could then disprove this as the source of the Sun''s energy. Gravitational Contraction as a Source of Energy Proposing an alternative explanation, British physicist Lord Kelvin and German scientist Hermann von Scientists soon realized that the
Once the Sun''s energy reaches Earth, it is intercepted first by the atmosphere. A small part of the Sun''s energy is directly absorbed, particularly by certain gases such as ozone and water vapor. Some of the Sun''s energy is reflected back to space by clouds and Earth''s surface. Most of the radiation, however, is absorbed by Earth''s
This process releases energy to the star since, as Aston showed, four hydrogen atoms are heavier than one helium atom. The same set of nuclear reactions that supply the energy of the sun''s radiation also produce neutrinos that can be searched for in the laboratory. This figure is a cross section of the sun.

From our vantage point on Earth, the Sun may appear like an unchanging source of light and heat in the sky. But the Sun is a dynamic star, constantly changing and sending energy out into space. The core is the hottest part of the Sun. Nuclear reactions here – where hydrogen is fused to form helium – power the Sun''s heat and light

Neutrinos produced in the center of the sun have been detected in five experiments. Their detection shows directly that the source of the energy that the sun radiates is the fusion of hydrogen nuclei in the solar interior. The nineteenth century debate between theoretical physicists, geologists, and biologists has been settled empirically.
Inside the Sun, this process begins with protons (which is simply a lone hydrogen nucleus) and through a series of steps, these protons fuse together and are turned into helium. This fusion process occurs inside the core of the Sun, and the transformation results in a release of energy that keeps the sun hot.
The source of the sun''s heat is nuclear fusion, which is option a in your question. Nuclear fusion is a reaction in which two lighter atomic nuclei join together to form a heavier nucleus, releasing a large amount of energy in the process, as depicted in Figure 16.5. The core of the Sun converts approximately 10³8 protons per second into
