The exact hour of sunset varies with the time of year and the location of the observer. It does not occur for long periods of time at the north and south extremes of the planet due to the axial tilt.
In general sunset occurs when the curve of the Earth occults the viewers straight line observation of the sun from his viewing location.
The rotation of the earth is what causes the sun to appear to set
Assuming you mean "why": if the Sun appears to set, that is the result of Earth's rotation.
No, the sun does not technically set into the sea. The Earth revolves around the sun which makes the sun appear to set into the sea especially when you are watching a sunset at the beach.
Because the Earth rotates on its axis, constantly spinning.
The earth rotates in a clock wise motion thus making the sun rise in the east and set in the west.
The Sun is at the centre of our solar system. the Earth not only orbits the Sun - but also spins on its axis. The spinning of the earth presents a different area of the planet's surface towards the Sun - making the sun appear to rise and set.
The Sun doesn't really rise and set; the Sun sits there in the center of our solar system, unmoving. It is the Earth spinning - and us with it - that makes the Sun appear to rise in the East and set in the west.
The sun appears larger from the Earth. The reason is that the Earth is closer to the sun.
The rotation and revolution of earth are responsible for it, but sometimes there is lunar eclipse.
No, it is due to the rotation of the Earth.
sun is the closest star to earth .
Stars appear different from the sun because the sun is closer to the earth and the other stars are further away from the earth so that's why the appear differently when you look at them in the sky!!!!!
