Detailed explanation-1: -The Earth’s orbit makes a circle around the sun. At the same time the Earth orbits around the sun, it also spins. In science, we call that rotating on its axis. Since the Earth orbits the sun AND rotates on its axis at the same time we experience seasons, day and night, and changing shadows throughout the day.
Detailed explanation-2: -Earth rotates because Sun attracts the earth and thus pulls earth towards it secondly due to earths revolution around sun it tends to go away from sun in direction of the tangent hence a rotational force (torque) acts on earth and it tends to rotate.
Detailed explanation-3: -But it appears to rise and set because of the Earth’s rotation on its axis. It makes one complete turn every 24 hours. It turns toward the east. As the Earth rotates toward the east, it looks like the sun is moving west.
