Day and Hours

A day can last 21 hours! Night and day happen because Earth is spinning as it circles the Sun. At the height of summer, places near the North Pole are so tilted towards the Sun that it is light almost all day long. In Stockholm, Sweden, Midsummer's Eve lasts 21 hours because the Sun disappeared below the horizon for only three hours.

Why There's Day and Night

At the North Pole, the Sun never disappears below the horizon at Midsummer's Day.

Decidous tresses lose their leaves in autumn, but evergreens keep their leaves all year round.

Forest change colour in the autumn. Autumn comes between summer and winter. Trees prepare for the cold winter months ahead by losing their leaves. First, though, they suck back precious green chlorophyll, or dye, in their leaves, making them turn glorious shades of red, orange and brown.

You don't believe it! When the Sun shines all day in the far north, there is a 24-hour night in the far south.
