4. Based on your observations, describe how the length of day is affected by latitude in the summer and in the winter. In your explanation, explain which latitudes are affected most by the seasonal change and which latitudes are affected least.

The latitudes that are located at east direction of the Prime Meridian will affect the most during summer time and those latitudes that are towards west direction, will be least affected.

Explanation:

Latitude is the angle produced at the centre of the earth by a line joining a place with the centre to the north and south of the equator and the imaginary line that connects the places of the same latitude is called a parallel of latitude.

As someone go towards east of prime meridian it can be seen that the time is gradually increasing as the sun rises in the east earlier.This is due to the rotation of earth from west to east.

And if someone moves towars west of the prime meridian, the time will decrease as the sun rises later in that area.
