Detailed explanation-1: -As Earth rotates in and out of daylight, an object’s shadow changes in length and direction over the course of a day. From Earth’s surface, the Sun appears to move across the sky from east to west. As the position of the Sun in the sky changes, the direction of incoming rays affects the shadow that an object casts.
Detailed explanation-2: -Because the Earth is rotating, the sun’s light shines on objects from different directions as the day goes on. This causes the sizes and shapes of shadows to change.
Detailed explanation-3: -Correct answer: The Earth’s rotation causes the shadows to change throughout the day. The rotation of the Earth also causes day and night. The Earth’s revolution causes slight changes in the length of these things because of its location in orbit.
