What is it called when the sun goes down over the horizon?

Answer 1

The same reason the scenery appears to go by when you're on a train looking out the window. You are in motion but your brain on some level thinks it's still, so it interprets what you see as if that were the case.

Answer 2

The sun appears to come up in the morning owing to the rotation of the earth. Because the earth spins on its axis, an observer on the earth's surface might notice alternating periods of dark and light every 24 hours because the portion of space visible to them changes due to this rotation; however, the sun itself is actually staying pretty much in the same place. Another factor to consider is that an observer is usually on the earth's surface, which creates a horizon, or a line of sight tangential to the planet's spheroidal shape, below which celestial objects would not be visible because the earth itself is opaque. At dawn the earth's rotation brings the sun over the limb of that horizon and the obsever notices the sun appearing to rise. The opposite happens at sunset, rotation obscures the sun again below the horizon on the opposite side.

Answer 3

The Sun doesn't really rise, it just looks like it does from our point of view. But when the Earth rotates, the sun gradually comes into view therefore making it look like it's the one moving.

Answer 4

because that's life! if the sun were not to rise every morning, life would not exist. but the sun itself does not rise, it stays in the same spot as it's always been. the earth circles around the sun while spinning on its axis all the time, so whichever part of earth is facing the sun means it's daylight in that time zone. when that zone begins to turn away from the sun, it begins to get dark out and stays night until that zone spins toward the sun again. thus, the sun 'rises' every morning when the area you live in is turning in the sun's direction.

Answer 5

The sun doesn't really rise and set.Earth is rotating every second and it faces the sun for hours and then rotates away from the sun and then faces the sun. It rotates every second that's why there's morning,midday, and evening.

Answer 6

The sun does not technically rise. Words like sunrise and sunset have carried over from a time when we believed that the Earth was at the center of the universe and that the sun revolved around it. However, it is actually the motion of the Earth that makes the sun appear to rise and set. The Earth rotates on its axis at a speed of approximately 1,000 MPH at the equator, making one complete rotation roughly every 24 hours. Thus, as one hemisphere of the earth rotates to face the sun, it appears to rise, and when that hemisphere rotates to face away from the sun, it appears to set.

Answer 7

It is not the sun comes up and in mornin. Morning,evening,north,south,east,west,poles etc are all we subtitued . they are all named by us for our convinience. We assumed that when sun risses it is morning.okay.

Answer 8

First, it is important to realize that it is the Earth that is moving, not the sun. The Earth is always rotating making it seem as if the sun is moving across the sky. When the Earth turns enough that the observer cannot see the sun any longer it is night time. When the Earth makes a complete rotation the sun comes back into sight, seeming to rise up from behind the horizon.

Answer 9

sunset
Sets. Hence, the term "sunset."

Answer 10

When the upper edge of the sun appears over the horizon, that is the sunrise.
