Question

2. Give geographical reasons:
(a) The local time is decided by the noon
time. ​

Answer 1

 a ): As soon as the sun starts moving up in the sky after sunrise, the length of our shadow reduces. Normally, the length of the shadow is shortest at noon. As the sun moves towards the horizon in the afternoon, the length of our shadow increases again by evening. The noon time is the same at any given longitude across the earth, i.e. from the North Pole to the South Pole. The time of a place as decided by the location of the sun in the sky, is known as its local time.

Answer 2

Explanation:

Local time of a particular place refers to the time determined under the basis of the sun's apparent movement ...when the sun is exactly over the head ,it is noon at that place .the length of the shadow is shortest at noon..the local time of each longitude differs from other..thus noon occurs at different times in different longitudes...
