The sun generates energy from a process called nuclear fusion. During nuclear fusion the high pressure and temperature in the sun’s core cause nuclei to separate from their electrons. Hydrogen nuclei fuse to form one helium atom. … Yet this amount of energy is enormous.
What is the connection between sunspots and solar radiation sent to Earth quizlet?
The effects of sunspots is to increase energy output from the suns surface and in turn the amount received by the earth. The amount of energy released by the sun varies by 0.1% each cycle.
How is energy produced in the sun core?
The sun generates energy in its core in a process called nuclear fusion. During nuclear fusion the sun’s extremely high pressure and hot temperature cause hydrogen atoms to come apart and their nuclei (the central cores of the atoms) to fuse or combine. Four hydrogen nuclei fuse to become one helium atom.
How does energy makes its way from the nuclear core of the sun to its atmosphere?
Energy is created in the core of the Sun by nuclear fusion which releases energy that moves by radiation through the radiative zone. After that this energy moves through the convection zone by rising of hot gas and sinking of cool gas.
Which of the following correctly describes how the Sun produces energy?
Which of the following correctly describes how the Sun produces energy? Four hydrogen atoms fuse into one helium atom. he Sun and other stars are powered by nuclear fusion.
Why is it usually impossible to see the Sun’s corona?
The corona is the outermost part of the Sun’s atmosphere. The corona is usually hidden by the bright light of the Sun’s surface. That makes it difficult to see without using special instruments. … During a total solar eclipse the moon passes between Earth and the Sun.
Where does the energy that the sun emits come from?
Solar energy is created by nuclear fusion that takes place in the sun. Fusion occurs when protons of hydrogen atoms violently collide in the sun’s core and fuse to create a helium atom. This process known as a PP (proton-proton) chain reaction emits an enormous amount of energy.
How and where does the sun make the energy we see quizlet?
Energy is made through the process of nuclear fusion. This is when two hydrogen nuclei join to make helium. This occurs in the sun’s core where there is very high pressure and temperature.
Where is the sun’s energy produced quizlet?
The sun’s energy is produced in its central region by the fusion of hydrogen nuclei into helium nuclei. What two forces in the sun interact to produce a stable structure? The sun remains stable because the inward pull of gravity balances the outward push of thermal pressure from nuclear fusion.
What type of energy is the sun quizlet?
Solar energy is the energy from the sun. Solar energy is a renewable (unable to be extinguished) energy resource. You just studied 12 terms!
How does the energy produced in the sun’s core reach the sun’s outer surface?
Energy moves through the sun in two main ways: by radiation and by convection. As energy moves outward from the sun’s core it first enters the radiation zone. … Energy from the radiation zone passes into the convection zone the outer layer of the sun’s interior.
How does the sun produce its energy quizlet?
the sun produces energy by the nuclear fusion of hydrogen into helium in its core.
How does the sun produce energy that heats our planet quizlet?
How does the Sun produce the energy that heats our planet? The core of the Sun has radioactive atoms that give off energy as they decay. Gas inside the Sun heats up when compressed giving off large amounts of energy. Heat trapped by magnetic fields in the Sun is released as energy.
Why is it usually impossible to see the sun’s corona from Earth quizlet?
Photosphere. Why is it usually impossible to see the sun’s corona from Earth? Because the glare from the photsphere blocks out the light from the corona. … The sunspots are cooler in temperature and therefor give off less light.
What type of energy is light from the sun quizlet?
Most of the energy from the sun travels to Earth in the form of visible light and infrared radiation. A small amount arrives as ultraviolet radiation. has wavelengths that are longer than red light. It is not visible but can be felt as heat.
How does the sun produce light?
The Sun produces light by a nuclear reaction called fusion. As atoms of hydrogen combine to form helium they produce vast amounts of heat and light. Sunlight appears white but it contains a mixture of all the colours of the rainbow: red orange yellow green blue indigo and violet.
Does the sun have infinite energy?
The sun in powered by nuclear fusion of hydrogen to helium. There is plenty of hydrogen remaining to keep the sun going for billions of years. So solar energy is not infinite but it will last for billions of years.
What color star is hottest?
Blue starsWhite stars are hotter than red and yellow. Blue stars are the hottest stars of all. Stars are not really star-shaped. They are round like our sun.
What happens in the core of the sun quizlet?
What happens in the center of the Sun? Nuclear fusion occurs – A process in which particles of an element collide and form a heavier element such as the fusion of hydrogen into helium that occurs at the Sun’s core.
What does the sun emit?
Our Sun emits light at progressively shorter wavelengths too: the ultraviolet X-ray and even gamma-ray parts of the spectrum. But most of the Sun’s light is in the infrared visible and ultraviolet parts of the electromagnetic spectrum. See also what capital lies directly on the prime meridian
Which layer of the Sun emits the sunlight we see on Earth?
The photosphere
The photosphere is the visible surface of the Sun (Figure 24.18). This is the region of the Sun that emits sunlight. It’s also one of the coolest layers of the Sun—only about 6700°C.
Why do all stars solar system planets and the Sun rise in the eastern sky and set in the western sky?
No this is not sensible because stars appear to rise and set as a result of Earth spinning on its axis so all stars have to rise in the eastern sky and set in the western sky. … This is sensible because stars move around Earth so some can move in one direction while others can move in the opposite direction.
Is the sun an energy source?
One of the most important sources of energy is the sun. The energy of the sun is the original source of most of the energy found on earth. We get solar heat energy from the sun and sunlight can also be used to produce electricity from solar (photovoltaic) cells. See also what is ecosystem diversity
