What if There Were No Seasons?
What causes the seasons to change? Seasons
are caused by a 23.5 degree tilt of the Earth’s
axis during its revolution.
The tilt is a slant of the Earth’s axis, a 23.5
The axis is the imaginary line that extends
from the North Pole to the South Pole and is
the center of the Earth’s rotation.
The Earth revolves around the sun. A
revolution is when one object moves around
another. It takes the Earth 365.25 days to
The Earth also rotates or spins on its axis.
The rotation of the Earth causes day and night.
With the 23.5 ̊tilt, one hemisphere tilted more
towards the sun than the other. If you live in
North America, which is in the northern
hemisphere, during the summer the northern
hemisphere is tilted towards the sun and
receives more direct sunlight.
A hemisphere is half of a sphere and Earth is
divided into the northern and southern
What would happen if the Earth didn’t tilt? We
wouldn’t have any seasons. It would be a
pretty different world that we live in. Our crops
wouldn’t grow correctly. If we didn’t have
Our Earth would also get colder and colder the
further you get from the equator. We couldn’t
live in some of the locations we currently live
in. If we had to live closer to the equator, we
wouldn’t have as much space to live, and our
populations would be lower. They would have
And what would life be like closer to the
equator? It would be even hotter and more
humid than it is now. Studies have shown that
we might have more diseases because disease
thrives in warmer climates.
All life on earth would be completely different
