Why does the distance between the earth and the sun change during the year?

Because Earth does not orbit the Sun in a perfect circle. If you were to look at the Earth's orbit, it would look like an oval. This is called an elliptical orbit. When the Earth is closer to the Sun (called perihelion), it goes faster than when it is farther (aphelion).
Also, the orbit of the planets will cause a slight wobble in the sun, so the Sun actually moves in accordance to the planets, however this is a very small wobble, and the proper answer to your question would be in the first paragraph.
This is a very small amount of info, and I would suggest you research more. =)

Why does the distance between earth and the sun differ during the year?
Simply because the Earth's path around the sun is not a circle. Earth's orbit is an ellipse - meaning its distance from the sun varies according to the time of year.
When the distance between the earth and the sun is minimum?
The distance between the earth and the sun is about 150 million km .
We know that Earth's orbit is a because the distance between Earth and the Sun changes during the year?
An ellipse. All orbits are ellipses; there are no natural circular orbits.
Is equal to the distance between the sun and the earth?
One "Astronomical Unit" is (more or less) the average distance between the Sun and Earth.
What is the Average distance of the earth from the sun during its orbit is?
150G meters is the average distance of the earth form the sun.
What between earth and the sun changes during the year?
distance
What is the distance between Earth from the sun during aphelion?
152,098,232 kilometers.
Why the distance of the earth and the sun changing constantly during its revolution?
The Earth's orbit around the Sun is elliptical, not a perfect circle. This means that the distance between the Sun and Earth is constantly altering during the orbit of the Earth.
Distance between the earth and the sun is the gretest during?
... the first week of July.
How does the distance between the earth and the moon change every year?
The moon gets closer and further to the earth during it's orbit, throughout the month. It is also slowly moving away from the earth by a few cm every year.
The distance between earth sun is the greastest during?
Aphelion, which generally occurs in July.
Can changes in distance between the Earth and the Sun explain seasons?
Not really, the change in distance produces a small effect compared to the differences between summer and winter caused by the tilt of the Earth's axis.
Which of these does not contribute to the changing of seasons A distance between the Earth and Moon B distance between Earth and Sun C distance between Earth and Venus D alignment of the Universe?
distance between the earth and the sun.
Why does the shape of the tidal bulge change during the course of the month?
As the orbits of the Moon about the Earth and the Earth around the Sun are not circular, the distance to each of these bodies varies. Since the strength of gravitational attraction is determined, in part, by the distance between the objects, as the distances change so too does the strength of the tide-raising forces.
Why does the distance between the earth and moon change?
It varies, since the moons orbit around earth is not perfectly circular and central.
What is the distance between the earth and sun in 2008?
The same as other years. The distance doesn't change much from one year to another.
What is the distance between the earth and the sun during the course of the year currently?
about 8 light minutes
