because the earth rotates on its axis
Its so easy cause the earth rotates on its axis, which cause this appearance to change in the day and night.
the earth rotates giving the illusion of the sun moving across the sky
The sun is always in the sky. But, as the earth rotates, some of the time (at night) your part of the earth is facing away from the so you think it is not in the sky.
The sky gets dark because the earth orbits the sun and rotates, so when the earth is not facing the sun, it gets dark.
The moon rotates on it's axis during the same time it takes the moon to go around the earth.
Stars appear to move across the Earth's sky each night due to the rotation of the Earth on its axis. As the Earth rotates from west to east, different stars become visible in the sky. This apparent motion is known as the diurnal motion of stars.
the earth rotates giving the impression of the sun moving across the sky
The Sun appears to move in the sky because we are on the Earth, which rotates once every 24 hours.
The same reason you have to look up to see the moon when you're standing on earth. From earth, the moon appears to move across the sky, but on the moon, the earth stays in the same spot at all times. This is because the near side of the moon is always pointing to earth while the earth rotates, which gives the moon the appearance of movement across the sky.
This is a simple one to answer. The Earth rotates and as it rotates, the stars seem to move across the sky.
