What's The Time Around The World

Question 1

Rotation:

Where does the earth rotate

On its axis around the sun

Question 2

Rotation:

As the earth rotates one half of the earth is what while the other is what

As it rotates, one half of it is lit (daytime), whereas the other half is in darkness (night)

Question 3

Rotation:

How long does it take for the earth to complete 1 full rotation

Answer 3

It takes the earth 24 hours to complete 1 full rotation, giving us 24 hours in one day

Question 4

Rotation:

What would happen if clocks were set at the same time across the world

Answer 4

It could be 9pm and daylight in some places

Question 5

Time zones:

To avoid the problem of it being daylight at 9pm in some places what did countries develop

Answer 5

To avoid this problem, countries developed their own local time. The world is now divided up into a number of time zones

Question 6

Time zones:

The time zones are broadly parallel to what and why

Answer 6

The time zones are broadly parallel to lines of longitude. This is because the earth rotates on its axis west to east

Question 7

Time zones:

Explain how time zones work

Answer 7

Each time zone is 15° of longitude in width. Time changes 1 hour forward or backwards depending on whether the time zone is east or west of Greenwich meridian
