How long does it take for energy from the Sun’s core to reach the top of the convective zone?
Although I've left all of the messy mathematics out, I calculated that while traveling at the speed of light, that photon would take about 264 years for a photon to travel from the core of the Sun to the Convection Zone.
How long does it take energy released in the core to make it out of the radiative zone?
It takes over 170 thousand years for the energy released in the core of the Sun to get out of the radiation zone!
How long does it take for energy to leave the Sun?
So, if you think photons only travel 0.1 millimeters between crashes, it will take more than half a million years for the photon to escape the sun. If you think it's about a centimeter, then it will take about 5,000 years for the photon to get outside the sun.
How long does it take the energy to reach Earth?
The short answer is that it takes sunlight an average of 8 minutes and 20 seconds to travel from the Sun to the Earth.
How is energy transported from the core to the surface of the Sun by radiation and by convection?
Explanation. Energy is transferred through electromagnetic radiation in the radiation zone. In this process, the particles repeatedly absorb and re-emit the waves until they reach the outermost part of the radiative zone. On the other hand, the energy is transferred through convection currents in the convection zone.
How long does it take for light from the center of the Sun to reach Earth?
The Sun is 93 million miles away, so sunlight takes 8 and 1/3 minutes to get to us.
How energy is generated in the core?
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. In its core, the sun fuses about 620 million metric tons of hydrogen every second.
What happens to light as it travels from the core of the Sun to the surface?
At core, the energy is released in the form of Gamma Rays. At the core, protons and helium nuclei are so thick that an emitted gamma ray can't get very far before it is absorbed. If you imagine that a gamma ray is emitted right at the center of the sun then it will start out heading right for the surface.
What happens in the core of the Sun?
The core of the Sun is home to billions and billions of atoms of hydrogen, the lightest element in the universe. The immense pressure and heat pushes these atoms so close to one another that they squish together to create new, heavier atoms. This is called nuclear fusion.
How long does it take to travel to the Sun?
At this speed, how many days would it take to travel to the sun from Earth, located at a distance of 149 million kilometers? Answer: Time = Distance/speed so Time = 149,000,000 km/ 28,000 = 5321 hours or 222 days.
How does energy travel through the Sun?
Radiation is the transfer of heat energy through space by electromagnetic radiation. Most of the electromagnetic radiation that comes to the earth from the sun is invisible. Only a small portion comes as visible light. Light is made of waves of different frequencies.
How does the energy from the core reach the surface of the Earth?
Summary. Heat from the Earth's core and radiation from the Sun is transferred to the surface of the Earth by conduction. Contact of the atmosphere with these warm surfaces transfers thermal energy, which then heats up the rest of the air through convection.
How the energy from the core is carried through the Earth’s surface?
Energy is transferred between the Earth's surface and the atmosphere in a variety of ways, including radiation, conduction, and convection. Conduction is one of the three main ways that heat energy moves from place to place. The other two ways heat moves around are radiation and convection.

What happens at the core of the Sun?
The core of the Sun is home to billions and billions of atoms of hydrogen, the lightest element in the universe. The immense pressure and heat pushes these atoms so close to one another that they squish together to create new, heavier atoms. This is called nuclear fusion.
How does energy in the solar core reach Earth?
The Sun's energy gets to the Earth through radiation, which you can prove just by standing outside and letting the sun's rays warm your face on a sunny day. Every object around you is continually radiating, unless its temperature is at absolute zero, at which point its molecules completely stop moving.
How long does it take light to travel from the surface of the Sun to Earth?
The Sun is 93 million miles away, so sunlight takes 8 and 1/3 minutes to get to us. Not much changes about the Sun in so short a time, but it still means that when you look at the Sun, you see it as it was 8 minutes ago.
How long is the core of the Sun?
86,000 – 110,000 miles The core of the Sun is considered to extend from the center to about 0.2 to 0.25 of solar radius (140,000 – 170,000 kilometres (86,000 – 110,000 miles)).
How many miles is the core of the Sun?
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. Temperatures top 27 million °F (15 million °C) and it's about 86,000 miles (138,000 kilometers) thick. The density of the Sun's core is about 150 grams per cubic centimeter (g/cm³).
How many seconds does it take for sunlight to reach the surface of the Earth?
Light travels at a speed of 299,792 kilometers per second; 186,287 miles per second. It takes 499.0 seconds for light to travel from the Sun to the Earth, a distance called 1 Astronomical Unit.
How many light minutes away is the Sun?
In light-years, the Sun is 0.00001581 light-years away, while in light minutes, the Sun is 8.20 light minutes away, or 500 light-seconds away from Earth.
How much energy is transferred from the sun to the surface?
About 23 percent of incoming solar energy is absorbed in the atmosphere by water vapor, dust, and ozone, and 48 percent passes through the atmosphere and is absorbed by the surface. Thus, about 71 percent of the total incoming solar energy is absorbed by the Earth system.

How does the energy produced by the Sun’s core reach the surface?
The Core. The Sun's core is the central region where nuclear reactions consume hydrogen to form helium. These reactions release the energy that ultimately leaves the surface as visible light.
How is energy transported to the surface of the Sun?
Radiation is the transfer of energy by electromagnetic waves (light). Only convection and radiation transfer are important in the Sun and the opacity determines which method is used. When the temperature is high and all the atoms are stripped of their electrons, the opacity is low and radiation transfer is dominant.
Why does it take 8 minutes for sunlight to reach Earth?
The Sun is 93 million miles away, so sunlight takes 8 and 1/3 minutes to get to us. Not much changes about the Sun in so short a time, but it still means that when you look at the Sun, you see it as it was 8 minutes ago.
How long does it take light to travel?
The speed of light traveling through a vacuum is exactly 299,792,458 meters (983,571,056 feet) per second. That's about 186,282 miles per second — a universal constant known in equations as "c," or light speed.
How long does it take light from the Sun to reach Earth?

How long would it take to travel to the Sun?
At this speed, how many days would it take to travel to the sun from Earth, located at a distance of 149 million kilometers? Answer: Time = Distance/speed so Time = 149,000,000 km/ 28,000 = 5321 hours or 222 days. Problem 2 – The planet Neptune is located 4.5 billion kilometers from Earth.
How long will it take to reach the Sun?
It would take 169,090 hours to fly there at 550 miles per hour. It would take 7,045 days to fly there at 550 miles per hour. It would take 19.3 years to fly there.
