If the country is in same time zone does it means that sun rises at the same time at all location?

Answer 1

The eastern side of the time zone would receive sunrise an hour before the western side would. Lines of latitude are 15 degrees apart (1 hour), which evenly divides the Earth into 24 equal sized strips, making each time zone "an hour difference."

To simulate this, take a globe and divide it into 24 equal sections (preferably using time lines). Turn the lights off and shine a flashlight on the globe from a far enough distance to shine light on the whole globe. Slowly spin the globe, noticing how the light falls on it.
