the earth is spherical in shape, so the rays of the sun cant touch every part of it at the same time, this y earth rotates and revolves round the sun, such that not only a particular section of the earth surface will enjoy sunlight, in such pattern all part of earth surface would enjoy sunlight, and moonlight( moonlight is the moons reflection of sunrays)

Because the earth is revolving

Are u trying to debunk flat earth theory??

Obviously, it shows that earth isn't flat

Bkayyy:
It is because of Corona and racism.

Something wey dey Integrated Science and Geography

ednut1:
dem no teach you geography in secondary school Time is 11.57am in canada now and its afternoon. Nigeria is about 6pm and its dark or getting dark. So why should we have same time

aNah Everybody read geography

edoairways:
Secondly,do you have an idea why we have longer day shorter night

This now leads to EQUINOX and SOLSTICE

no mind am jawe! make e go back school go learn am no be by force to bring thread come here

very good ansa.Wetin consign Arts with science?

For your information is not all students that offer geography in secondary schools. So you need to learn how to respond to people's questions or post politely.

you geh time sha

Op it's because of the rotation of the earth ,if the earth rotates you country away from the sun then it become evening or night ,the other part that faces the sun becomes day.
Simple geography.

Hey guys,

Can we throw more light on this topic.

Why do countries all over the world have different time zone?

For instance, the difference between Nigeria and UK time is just like 2 hours.

Nigerian and Canada time is like 6 to 7 hours difference. So the question is what is the rationale behind this time perspective?

clearly you didnt go to school, you are the people Afe babalola was talking about.

MalaikaEH:
Okay, OP, let me teach you in primary school tone and voice.

My instructional material is a flashlight (touch) and a spherical globe containing map of the world. For easier understanding, take the materials to a dark room where the only source of light is the touch light.

Now, the touch represents the sun and should be kept on a chair at one corner of the room. The sun is the only source of light in the whole universe. The moon and stars merely reflect rays of light from the sun. The sun does not move at all. It is stationary and shines constantly without stopping. So, in this dark room, keep the touch light shining at one place towards the globe without offing it.

Back to the globe, make it stand constantly on the south pole with Australia near it, while the North Pole is constantly upside with Siberia, Alaska and Northern Russia close to it.

Now, set the globe in such a way that the light is shining directly on the map of Nigeria on the globe. In real world, that happens around 12pm in Nigeria. Other countries on the same line (latitude) with Nigeria, such as Italy, Libya, Tunisia, Niger, Germany, etc have their 12pm at the same time. So, it is said that they are on the same time zone.

At this same time, countries and areas directly behind Nigeria on the other side of the globe will have their 12am (i.e. Mid night) because the light from the touch (sun) can not reach them.

The earth rotates anti-clockwise on its axis (meaning that it turns round and round slowly on the South Pole side). So, we turn our globe so that the touch light now shines directly on the map of Ghana, Mali, UK, Spain, etc . In reality, it takes the earth complete 1 hour to make this turn. So, the time zone around the world would have changed by 1 hour. Time in Nigeria becomes 1pm when Ghana has 12pm, At this same time, Senegal would be having 11am. The earth and time continue to move until Nigeria will reach behind the light, which is night. At 12am (mid night) in Nigeria, some countries facing the sun will have their mid day. It takes 24 hours for the earth to rotate completely on its axis. That is what we call one day.

Also, the earth revolves around the sun. That means it continues moving, apart From rotating, until it has gone round the sun. This takes 365 and one quarter days to complete. That is one year.

I hope you all understand today's lesson.

Apt.

I believe if you did Geography in school op, you would have known why.
This is entirely a study on it own, don't come and ask why we have day and night later.

Its the special work of God.

na why moon dey disappear I won know. Where e dey go ... & y crescent & full moon dey form. wetin dey block am??

Because the earth is revolving

Rotation of the earth causes day and Night(24 hours) while Revolution takes 365 1/4 days to complete a Cycle

tunene66:


There is no time difference between Nigeria and UK hour between the last Sunday in March and the last Sunday in October each year. That is called the British Summer Time .
All other times of the year the UK time is one hour behind that of Nigeria.

Why the time difference.
Basically the earth is not flat, it is spherical and it rotates everyday on its axis, meaning that sunlight does not reach each place on earth the same time and in the same intensity. So when it is day in some places, at the same time in other places it is night.

U still didn't answer the questions of why we have different time...

Here, maps give a more easier representation.

Keep in mind there is no accurate way to display a sphere on a flat surface, so there are going to be distortions.

Priapus69:
The Earth is a sphere that rotates around its axis while the sun is stagnant.

Everything in the universe is in constant motion....so the sun is not stagnant

the planet earth rotates slowly over a 24 hour period. as it's doing this parts of the planet are exposed to sunlight which is called day while other parts of the planet are left in darkness which we call night. the time zones indicate the different periods that the earth has rotated.

Canada is 6-7 hours behind because our part of the world rotates and sees the sun before they do. with the uk the time is the same or one hour difference depending on the time of the year. plus because nigeria and uk are relatively in the same area of the earth when it rotates to meet the sun the time zone will roughly be the same.

you will notice also that countries like australia, china, japan are several time zones ahead of us that is because their part of the planet is furthest from us so they would get sunshine before we do. hope this helps

Na wah oo. This one too na question?

Have you heard of Longitude and Latitude before?


Countries in same longitude will be on same time zone(this is bar political and economic reason, simply geographic), while countries in same latitude have similar climate(this is not always the case though).


As for the earth being spherical and rotates leading to day and night, I think many on this thread have done justice to that.

Mbataku96:
This one is simple naa, the sun does not shine everywhere at the same time, so time is not the same everywhere.
That's why we all are 15 minutes in a different time zone.

.olodo
U mean to say 15degree reps one hour

hinograce:
I think receiving sun light doesn’t make the time difference. Someone should explain how some area have 3months of daylight ie no night for months in say Canada. In my opinion day time and night time doesn’t affect the time zone. The question is why are there different times in different locations of the earth at the same instance? I am curious like the op

Exactly though.. I remember at a time I was in Yola Adamawa state, by 5am it's complete day as everyone would be seeing clearly and by 6pm everywhere is dark!!! Whereas my folks down south are always suprised if I tell them this when they called.. If the sun/day determines the time then Lagos should not be using the same time with Yola!!

BigDawsNet:



Earth rotates, different parts of Earth accept sunlight or darkness, giving us day and night. As your location on Earth rotates into sunlight, you see the sun rise. ... As this occur... It will make us have different time zones.

Another olodo..
The only thing rotation of the earth causes is day night...answer the question for d different time zones

All of u talking about rotation of the earth seem to forget their geography..awon olodo..
Just answer the question based on longitude n time...and leave day n time out of it....

Do you mean the brightlight of the sun is constant,regardless of time?!
