Answer:
The apparent motion of the sun, caused by the rotation of the Earth about its axis, changes the angle at which the direct component of light will strike the Earth. From a fixed location on Earth, the sun appears to move throughout the sky.

Answer:
During the year the earth moves around the sun. As a result, the sun appears to move around the sky once with respect to the stars as seen from Earth.
Earth takes about 365 and a quarter days to travel once around the sun. Since the earth moves around the sun and we are resident on the earth, it means that the sun appears to shift in the sky about 1 degree per day. This number is calculated by taking the total degrees in a circle (360 deg, since the earth moves 360 degrees around the sun) and dividing that amount by the total number of days in a year (365.2422). The result is 360 deg / 365.2422 days to equal about 1 degree per day.
The plane of the earth's orbit is called the ecliptic. Since the earth orbits the sun, the sun is also on the ecliptic. As a result, the sun appears to us to move around the sky on the ecliptic.
Please note that the ecliptic is not the same thing as the earth's extended equator, the celestial equator. The earth's axis (and hence also the celestial equator) is actually tilted by 23.5 degrees with respect to the plane of the earth's orbit, or the ecliptic.
