Why do stars appear higher in the sky than its actual position?

This is called refraction and it is due to the bending of the ray of light from the star as it enters the atmosphere which has a changing refractive index at different heights.
This effect occurs at all heights (angles) but is more noticeable close to the horizon and it alters the time of sunrise and sunset by a few minutes.

What causes the stars in the sky to appear to be moving?
The Earth's rotation. The relation between the Earth (or a person on the Earth) and the position of the stars makes it appear that the stars are in a different position as the night progresses.
Are the stars visible 7 pm still visible at 11 pm in their original position why do you see so?
Yes, relative to more distant stars, their position will not have changed. See should be changed to stay in the question.
What is the actual amount of light a star gives off?
It is actually absolute magnitude, opposed to apparent magnitude which is how much light stars appear to give off.
Why do stars and the sun appear different?
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!!!!!
How did stars appear?
Stars in the sky appear at night time. If it is cloudy outside, stars will not be able to be seen by the naked eye. The moon also appears at night time.
What causes the stars in the sky to appear to be moving?
The Earth's rotation. The relation between the Earth (or a person on the Earth) and the position of the stars makes it appear that the stars are in a different position as the night progresses.
What time do stars come out at night?
Stars start to appear as the sun sets. The actual time will depend on the location throughout the world.
Why do the stars appear to rotate around Polaris?
It's an illusion caused by the actual rotation of the earth.
Why do some stars appear bigger and brighter than others?
A stars brightness depends on two factors; its distance from us and its actual brightness (absolute magnitude). The actual brightness of a star depends on various factors, such as its mass, its temperature and its age.Consider two stars of the same actual brightness (absolute magnitude) - if one of them is much closer, then is will be brighter than the further one. It will appear brighter, even though it would be the same side by side - it can be said to be apparently brighter (higher apparent magnitude) due to its distance.A:They appear bigger and brighter because they really are bigger and brighter, but even if they are not bigger and brighter it could be because they are closer.

When esimating the distance of the stars from earth astronomers use the fact that nearby stars shift in position as observed from earth which is called?
Nearby stars appear to change their position against the distant background in an annual cycle, because of the Earth's changing position 'across' its orbit. This apparent shift is called the star's "parallax".
Why do stars appear to shift position as you observe them one month and then again on the same date the next month?
the earth is rotating and revolving, so they are appear in different places
It cause stars to move apparently in one night?
The rotation of the Earth makes the stars appear to move in a circle, as viewed from the observer's position. The stars are always there, it is just that we can't see them during daylight.
What is higher for closer stars A absolute magnitude B red shift C parallax D blue shift?
The answer would be C) Parallax.The Absolute Magnitude of a star is the star's actual brightness, and is therefore not dependent upon the position of the observer.Red Shift and Blue Shift are consequences of a stars speed relative to the observer. Again this is independent of the stars proximity to the observer.Parallax, is the apparent change in position based upon the motion of the observer, and is directly proportional to the proximity of the object. Just as, when driving on the road distant trees or buildings don't appear to zoom past you as quickly as a pedestrian on the side of the road, so it is with stars. The closer they are the larger the parallax is as the Earth orbits the Sun, for example.
Why do stars appear distant if you supposedly only see the light that they emit?
All sight its based on the light that objects either emit, reflect, or refract. The stars are little different in this regard. We judge distance using a number of different cues, a number of which indicate that the stars are far away.More distant objects will tend to appear smaller. The stars appear small.Any object that blocks a portion of the sky will block the stars from view, so we know the stars are more distant than those objects.When we move, objects we are looking at appear to change position relative to us. The farther away they are, the smaller the change. No matter how much we move there is no apparent change in the position of the stars, meaning they must be very far away.Indeed, the stars are much farther away than they appear to be as we are not able to perceive such distances directly.

Yes, relative to more distant stars, their position will not have changed. See should be changed to stay in the question.
What would happen to the position of the north star if you found it every hour?
It would not change. Other stars will appear to have moved, but it won't.
