GEOLOGY

Detailed explanation-1: -The rotation of the earth causes day and night. As the earth is spherical in shape, only one half of it is illuminated by the sun at a time. The other half remains dark. The illuminated portion of the earth experiences day and the other part of the earth experiences night.

Detailed explanation-2: -Rotation causes a deflection of ocean and air currents. The earth rotates much faster than the winds or currents move. This causes a large g deflection in the direction that winds move and ultimately results in rotation around low pressure cells and high pressure cells.

Detailed explanation-3: -Earth’s rotation is slowing slightly with time; thus, a day was shorter in the past. This is due to the tidal effects the Moon has on Earth’s rotation. Atomic clocks show that a modern day is longer by about 1.7 milliseconds than a century ago, slowly increasing the rate at which UTC is adjusted by leap seconds.

Detailed explanation-4: -Day and Night. Dawn and Dusk. Differences in time zones. Deflection of the current of the Wind and Ocean. Apparent Sunrise and Sunset. Daily rising and falling of the tides. 20-Jan-2023
