Why do we have seasons?

The tilt of the Earth’s axis

When the Southern Hemisphere is receiving the most concentrated sunlight, what season is it in the

Northern Hemisphere?

Winter

What is a rotation and how long does it take the Earth to make 1

complete rotation?

Earth spinning on its axis (causes day and night)

1 rotation = 24 hours (1 day)

Draw a picture illustrating all 4 seasons with the sun

in the middle

What season is illustrated in the picture

below?

Summer

What is a revolution and how long is 1 Earth

revolution?

Revolution = Earth moving around the sun

1 Revolution = 1 year (365 days)

What could we change to decrease the length of day?

Increase the speed of the Earth’s rotation

If the Northern Hemisphere is getting indirect sunlight and the days are shorter, what season is it in the southern

Hemisphere?

Summer
