Effects of the Earth’s rotation are:

• The rotation of the Earth causes the day and the night. The part of the Earth facing the Sun experiences day while the part which does not face the Sun experiences night.
• The speed of the Earth’s rotation has affected the shape of the Earth. Because of the speed of rotation, a centrifugal force is created which leads to the flattening of the Earth at the poles and a bulging at the center.
• The Earth’s rotation affects the movement of water in the oceans. The tides are deflected due to the rotation.
• The speed of rotation also affects the movement of the wind. Due to rotation, winds and ocean currents deflect to the right in the Northern Hemisphere and to the left in the Southern Hemisphere.
• It causes differences in time at various places on the Earth. The difference in time of each longitude is 4 minutes.
