They are the Corona, the Visible Surface, the Solar and the Chromosphere. The sun is a huge hot ball of gases which are mostly hydrogen and helium. It has an innermost part, the core, in which light and heat energy are produced. The temperature in the core is about 15 million debgrees Celsius. The energy produced in the core travels to the surface in two ways. First, it travels in the form of radiant energy through the radiation zone. This zone has a temperature of 2.5 million degrees Celsius. From this zone. the energy travels by convection through the convection zone. Here, the gases undergo violent motions and carry most of the sun's energy to the surface of the sun. The photosphere, which is over 500 kilometers thick, is the apparent yellow surface of the sun. However, the sun is purely gaseous, so the photosphere is just the visible area of the sun's atmosphere. The temperature here is about 5500 degrees Celsius. Light is given off from the photosphere. The photosphere contains millions of granules. These are small patches of gases that look bright. A granule lasts for only a few minutes and then fades away. Other graanules take the places of those which have faded. The combined motion of all the granules makes the photosphere appear to be boiling. Extending about ten thousand kilometers from the photosphere is the chromosphere.
The chromosphere looks red because of glowing hydrogen gas. The top of the chromosphere contains spicules. These spicules are gas columns believed to be continuations of the violent motions of granules in the photosphere. Spicules can shoot about 16 000 kilometers into the corona. The outermost portion of the sun's atmosphere is the corona. It is estimated to have a height of more than a million kilometers. The corona is visible only when there is a total eclipse of the sun. When the sun's disk is darkened by the moon's shadow, the corona is seen as a faint light. At the corona's temperature of 1 million degrees Celsius, the particles of gas begin to escape the sun's gravity and flow outward into space. This flow of gas particles is called the solar wind. At a speed of 500 km/s, the solar wind takes a few days to reach Earth. Radiation, on the other hand, travels from the photosphere at the speed of light (3.0 x 10 to the fifth power km/s) and reaches Earth in eight minutes. The words with BOLD are the sun's parts namely: * core * photosphere * chromosphere * corona
The different parts of the Solar System attract one another through gravity. Since the Sun has most of the mass of the Solar System, other objects are mainly attracted to the Sun.
Earth revolves,so we can see different parts of the night Sky as it orbits the sun
As the moon travels around the Earth, different parts of it are lighted by the sun. We see various parts of the face that are being lit by the sun. Since the sun and shadow move around the moon, we see different parts of the moon face, or phases of the moon.
The sun rotates on its axis approximately once every 27 days. This rotation period can vary slightly due to the sun's differential rotation, where different parts of the sun rotate at different speeds.
Astronomers have inferred that the Sun rotates by observing the motion of sunspots across its surface. This phenomenon, known as differential rotation, causes different parts of the Sun to move at different speeds, indicating that the Sun rotates. Additionally, observations of the Doppler shifts in the light emitted by different regions of the Sun also provide evidence of its rotation.

It changes by the sun's reflection on different parts of the moon

it is because the sun is facing on the side of the earth and as it rotates, the side that gets the sun switches
Angles the sun hits us at different angles

Unlike Earth and other solid objects, the entire Sun doesn't rotate at the same rate of gas and plasma, different parts of the Sun spin at different rates.

As the earth rotates, different parts of the earth face the sun, that's day. The parts rotated away from the sun don't get any light, so it's night there. So when the earth spins, it faces different directions, away from the sun and facing the sun.
The location of the sun..location location location. lol
Because they are at different parts of the world and they are farther or closer to the sun at different times.
The sun looks like it rises and sets is because the Earth is constantly rotating, making the sun's light hit different parts of the earth at different times.
