Stars shine because they are extremely hot (which is why fire gives off light — because it is hot). The source of their energy is nuclear reactions going on deep inside the stars. In most stars, like our sun, hydrogen is being converted into helium, a process which gives off energy that heats the star.
What is responsible for making stars shine quizlet?, Stars shine because hydrogen fusion takes place inside their core which creates energy.
Furthermore, What is responsible for making stars shine protons the sun the moon photons?, The simple answer is that deep inside the core of the Sun, enough protons can collide into each other with enough speed that they stick together to form a helium nucleus and generate a tremendous amount of energy at the same time. This process is called nuclear fusion.
Finally, What process causes stars to glow?, In stars, nuclear fusion usually turns hydrogen atoms into helium ones. This fusion process creates huge amounts of radiation, light, and energy in the core of the star. … Eventually, that light reaches your eyes in the form of sunlight or shining stars.
Frequently Asked Question:
What are stars made up of and why do they shine?
Stars are made of very hot gas. This gas is mostly hydrogen and helium, which are the two lightest elements. Stars shine by burning hydrogen into helium in their cores, and later in their lives create heavier elements.
What are stars made up of?
Stars are huge celestial bodies made mostly of hydrogen and helium that produce light and heat from the churning nuclear forges inside their cores. Aside from our sun, the dots of light we see in the sky are all light-years from Earth.
Why do stars shine only at night?
Stars are present in the sky at both day and night. … During the day, the light of the Sun makes our sky so bright that we cannot see the much dimmer stars. At night, in the absence of the Sun, the sky becomes dark and the light of the stars can be seen. That is why, we are able to see the stars clearly only at night.
Do stars shine on their own?
The stars make their own light. The Moon, planets, asteroids, natural satellites, and comets shine by light reflected from the Sun.
Do stars get their light from the sun?
Stars make their own light, just like our sun (the sun is a star — the closest star to Earth). … They reflect the light of the sun in the same way our moon reflects sunlight.
What causes a star to glow?
But why do stars shine at all? … The intense pressure and temperature at the core of a star allow nuclear fusion reactions to take place. This is where atoms of hydrogen are fused into atoms of helium (through several stages). This reaction releases an enormous amount of energy in the form of gamma rays.
What reactions generate heat and light in stars?
This process is called nuclear fusion. Every second, a star like our Sun converts 4 million tons of its material into heat and light through the process of nuclear fusion. Our Sun has provided an essentially constant amount of heat and light to Earth for about 4.5 billion years.
What are stars made up of and why do they shine?
Stars are made of very hot gas. This gas is mostly hydrogen and helium, which are the two lightest elements. Stars shine by burning hydrogen into helium in their cores, and later in their lives create heavier elements.
What is the source of a star’s energy?
For the Sun and other normal main-sequence stars, the source of energy lies in the conversion of hydrogen to helium. The nuclear reaction thought to occur in the Sun is called the proton-proton cycle.
What is responsible for making the stars shine?
Stars shine because hydrogen fusion takes place inside their core which creates energy. When the temp reaches above 10 million K, hydrogen atoms are able to overcome the electromagnetic force, that repels like charges, and let the strong nuclear force, which binds protons and neutrons in a nuclei, take effect.
What is responsible for making stars shine Question 2 options protons the sun the moon photons?
The light energy emitted at the core of stars is carried by photons. Thus, we can say that photons is responsible for making stars shine.
What makes the sun and stars shine?
Stars shine because they are extremely hot (which is why fire gives off light — because it is hot). The source of their energy is nuclear reactions going on deep inside the stars. In most stars, like our sun, hydrogen is being converted into helium, a process which gives off energy that heats the star.
Do photons make stars shine?
Over time, electromagnetic energy particles called photons make their way to the surface and launch into space as solar wind. Eventually, that light reaches your eyes in the form of sunlight or shining stars.
What is responsible for making stars shine?
Stars shine because they are extremely hot (which is why fire gives off light — because it is hot). The source of their energy is nuclear reactions going on deep inside the stars. In most stars, like our sun, hydrogen is being converted into helium, a process which gives off energy that heats the star.
What causes a star to shine brightly quizlet?
The process by which nuclei of small atoms combine to form a new, more massive nucleus; this process releases energy. The light waves from a star appear to have longer wavelengths as the star moves away from Earth. … The gas is so hot, it causes nuclear fusion, and nuclear fusion causes stars to shine.
How does a star get its energy to glow quizlet?
Huge sphere of glowing gas mostly made up of hydrogen and they produce energy through the process of nuclear fusion. The process of nuclear fusion gives off light and heat. … You just studied 17 terms!
What are stars made from quizlet?
Stars are made of mostly hydrogen gas, but may include other elements (such as helium, or calcium). Elements in a star absorb different wavelengths of light, which emit different colors.
