1 and 2 only

1 and 3 only

1, 2 and 3

3 only

Explanation:

The earth rotates on its axis taking approximately 24 hours to complete one rotation. It has some important environmental consequences:
i. Rotation creates a diurnal cycle of light and darkness, temperature, and humidity changes.
ii. Rotation requires the creation of standardized time zones. There are 24, one for each hour of the earth's rotation.
iii. Rotation causes the tides - the twice daily rise and fall of sea level. Tides are complicated because they are the result of both the gravity of the moon and the gravity of the sun. Sometimes the sun and the moon are lined up with the earth, but most of the time they are not. Tides are highest when the earth, sun and moon are in a straight line.
